在阿里云Ubuntu14.04找不到php7版本的apt安装包，所以，只能利用源码来安装，中间遇到不少坑，在和mysql、Nginx配置时又出现了问题，所以，这里记录下来。
一、apt安装mysql
1、获取包
1、之前系统安装了mysql5.5版本，这里我们直接卸载,如果之前没安装过的可以跳过该步骤。
# 首先删除mysql:
sudo apt-get remove mysql-*
# 然后清理残留的数据
dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P2、更新包：
apt update3、查找可安装的mysql版本
apt-cache search mysql打印：
...
mysql-server-5.6 - MySQL database server binaries and system database setup
mysql-server-core-5.6 - MySQL database server binaries
mysql-source-5.5 - MySQL source
mysql-source-5.6 - MySQL source
mysql-testsuite - MySQL testsuite
mysql-testsuite-5.5 - MySQL testsuite
mysql-testsuite-5.6 - MySQL 5.6 testsuite可以看到我们的包资源有 mysql-server-5.6 版本。
4、安装
apt-get install mysql-server-5.6在安装的过程中会需要输入数据库密码，直接输入即可。
5、检查mysql是否运行
安装成功后，使用如下命令查看是否正常运行：
sudo service mysql status可以看到mysql已经安装成功在运行了：
root@iZ:/tmp# sudo service mysql status
mysql start/running, process 8482、修改配置
6、更改配置
先进入到mysql服务：
#用户名为root,密码假设是123456
mysql -uroot -p123456更改root访问的IP权限,否则外网连接会被拒绝的。
> use mysql;
> update user set host='%' where user = 'root' and host = '::1'7、修改MySQL监听IP
默认情况下MySQL监听的是127.0.0.1，也就是本机，所以只有本机能够连接上，因此需要将MySQL改成监听远程主机IP或者所有IP。
打开配置文件 /etc/mysql/my.cnf, 找到 bind-address，如果监听固定远程IP，则改成远程主机IP，若监听所有IP，则改成0.0.0.0或者注释bind-address，我们这里直接注释掉，修改完成后重启。
#bind-address = 127.0.0.1重启mysql
service mysql restart8、完整的 my.cnf 配置内容：/etc/mysql/my.cnf
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html
# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...

# * InnoDB
#
# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
# Read the manual for more InnoDB related options. There are many!
#
# * Security Features
#
# Read the manual, too, if you want chroot!
# chroot = /var/lib/mysql/
#
# For generating SSL certificates I recommend the OpenSSL GUI "tinyca".

可以看到，我们新增了几个参数到该配置文件：
#5.6兼容5.7出现的mb4索引超过限制问题
innodb_large_prefix = ON
innodb_file_format = BARRACUDA
# 最大连接数10000，默认数很小
max_connections = 10000好了到目前为止，我们已经使用apt成功安装了mysql5.6。
二、源码编译安装php7.0
1、下载源码
源码包我们放在/var/software目录下：
root@i:/var/software# wget http://am1.php.net/distributions/php-7.0.0.tar.gz2、解压安装
1、解压
cd /var/software
tar -zxvf php-7.0.0.tar.gz
cd php-7.0.02、编译
root@i:/var/software/php7.0# ./configure --prefix=/usr/local/php7.0 --with-config-file-path=/usr/local/php7.0 --enable-mbstring --enable-ftp --with-gd --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-pear --enable-sockets --enable-zip --enable-fpm --enable-xml --enable-sockets --with-gd --with-zlib --with-iconv --enable-zip --enable-pcntl --enable-cli --with-openssl --with-curl --prefix表示php安装到哪个路径，如果不写系统会默认放到一个路径，我们也安装php必须用的扩展pdo_mysql,openssl,curl等等。
我们将 php7 安装到 /usr/local/php7.0 目录下。
3、编译安装：
make && make install4、测试：
我们安装的目录在：/usr/local/php7.0,该目录下有这几个文件夹。
drwxr-xr-x 2 root root 4096 Nov 28 23:22 bin
drwxr-xr-x 3 root root 4096 Nov 29 09:40 etc
drwxr-xr-x 3 root root 4096 Nov 28 23:17 include
drwxr-xr-x 3 root root 4096 Nov 28 23:17 lib
drwxr-xr-x 4 root root 4096 Nov 28 23:17 php
drwxr-xr-x 2 root root 4096 Nov 28 23:22 sbin
drwxr-xr-x 4 root root 4096 Nov 28 23:17 var
进入到安装目录后，然后通过命令./bin/php -m查看扩展：
# cd /usr/local/php7.0
# ./bin/php -m
[PHP Modules]
Core
ctype
date
dom
fileinfo
filter
hash
iconv
json
libxml
pcre
PDO3、简化PHP执行命令
我们可以看到，如果要执行php脚本，需要根据php完整路径来执行/usr/local/php7.0/bin/php -m,这样会很繁琐，非常麻烦，如果设置一个别名，后边直接跟一个脚本就非常简单，比如这样：php -m，是不是非常简洁？
修改执行命令需要将执行的命令添加到配置文件 /root/.bashrc中：
vim /root/.bashrc# 新增php快捷命令
alias php=/usr/local/php7.0/bin/php重新加载：
source /root/.bashrc这样，我们就可以直接使用 php 来执行命令了，即查看php版本：
root@i:/usr/local/php7.0# php -v
PHP 7.0.0 (cli) (built: Nov 28 2019 23:16:55) ( NTS )
Copyright (c) 1997-2015 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2015 Zend Technologies
4、php-fpm配置
为php-fpm命令建立软链接，加入到环境变量中
ln -s /usr/local/php7.0/sbin/php-fpm /usr/local/sbin/php-fpm复制php配置文件目录下的 php-fpm.conf.default，并重命名为 php-fpm.conf
cp /usr/local/php7.0/etc/php-fpm.conf.default /usr/local/php7.0/etc/php-fpm.conf编辑 php-fpm.d/www.conf，设置 php-fpm 模块使用 www-data 用户和 www-data 用户组的身份运行,监听者也是www-data。
user=www-data
group = www-data
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
listen=/usr/local/php7.0/var/run/php7.0-fpm.sock这里有一个大坑，搞了好久好整明白，默认是监听 listen=127.0.0.1:9000，在Nginx fastcgi_pass 我们使用的是socket监听的，所以，这里需要改为socket监听模式：
listen=/usr/local/php7.0/var/run/php7.0-fpm.sock这个路径 /usr/local/php7.0/ 是我们的php安装路径，如果使用其他路径，会找不到 php7.0-fpm.sock 文件的，所以，这里必须是你的PHP安装路径，另外，php7.0-fpm.sock 默认是不存在的，在运行时才会产生。
root@i:/usr/local/php7.0/var/run# ls -l

www.conf完整配置：
路径：/usr/local/php7.0/etc/php-fpm.d/www.conf
; Start a new pool named 'www'.
; the variable $pool can we used in any directive and will be replaced by the
; pool name ('www' here)
[www]
; Per pool prefix
; It only applies on the following directives:
; - 'access.log'
; - 'slowlog'
; - 'listen' (unixsocket)
; - 'chroot'
; - 'chdir'
; - 'php_values'
; - 'php_admin_values'
; When not set, the global prefix (or /usr/local/php7.0) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
user=www-data
group = www-data
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific IPv4 address on
; a specific port;
; '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses
; (IPv6 and IPv4-mapped) on a specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
;listen = 127.0.0.1:9000
listen=/usr/local/php7.0/var/run/php7.0-fpm.sock
; Set listen(2) backlog.
; Default Value: 511 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 511
; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
; mode is set to 0660
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
; When POSIX Access Control Lists are supported you can set them using
; these options, value is a comma separated list of user/group names.
; When set, listen.owner and listen.group are ignored
;listen.acl_users =
;listen.acl_groups =
; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1
; Specify the nice(2) priority to apply to the pool processes (only if set)
; The value can vary from -19 (highest priority) to 20 (lower priority)
; Note: - It will only work if the FPM master process is launched as root
; - The pool processes will inherit the master process priority
; unless it specified otherwise
; Default Value: no set
; process.priority = -19
; Choose how the process manager will control the number of child processes.
; Possible Values:
; static - a fixed number (pm.max_children) of child processes;
; dynamic - the number of child processes are set dynamically based on the
; following directives. With this process management, there will be
; always at least 1 children.
; pm.max_children - the maximum number of children that can
; be alive at the same time.
; pm.start_servers - the number of children created on startup.
; pm.min_spare_servers - the minimum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is less than this
; number then some children will be created.
; pm.max_spare_servers - the maximum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is greater than this
; number then some children will be killed.
; ondemand - no children are created at startup. Children will be forked when
; new requests will connect. The following parameter are used:
; pm.max_children - the maximum number of children that
; can be alive at the same time.
; pm.process_idle_timeout - The number of seconds after which
; an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic
; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don't
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 15
; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 2
; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 1
; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 3
; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to 'ondemand'
; Default Value: 10s
;pm.process_idle_timeout = 10s;
; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
;pm.max_requests = 500
; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. It shows the following informations:
; pool - the name of the pool;
; process manager - static, dynamic or ondemand;
; start time - the date and time FPM has started;
; start since - number of seconds since FPM has started;
; accepted conn - the number of request accepted by the pool;
; listen queue - the number of request in the queue of pending
; connections (see backlog in listen(2));
; max listen queue - the maximum number of requests in the queue
; of pending connections since FPM has started;
; listen queue len - the size of the socket queue of pending connections;
; idle processes - the number of idle processes;
; active processes - the number of active processes;
; total processes - the number of idle + active processes;
; max active processes - the maximum number of active processes since FPM
; has started;
; max children reached - number of times, the process limit has been reached,
; when pm tries to start more children (works only for
; pm 'dynamic' and 'ondemand');
; Value are updated in real time.
; Example output:
; pool: www
; process manager: static
; start time: 01/Jul/2011:17:53:49 +0200
; start since: 62636
; accepted conn: 190460
; listen queue: 0
; max listen queue: 1
; listen queue len: 42
; idle processes: 4
; active processes: 11
; total processes: 15
; max active processes: 12
; max children reached: 0
;
; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the query string will return the corresponding
; output syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
; http://www.foo.bar/status?full
; http://www.foo.bar/status?json&full
; http://www.foo.bar/status?html&full
; http://www.foo.bar/status?xml&full
; The Full status returns for each process:
; pid - the PID of the process;
; state - the state of the process (Idle, Running, ...);
; start time - the date and time the process has started;
; start since - the number of seconds since the process has started;
; requests - the number of requests the process has served;
; request duration - the duration in µs of the requests;
; request method - the request method (GET, POST, ...);
; request URI - the request URI with the query string;
; content length - the content length of the request (only with POST);
; user - the user (PHP_AUTH_USER) (or '-' if not set);
; script - the main script called (or '-' if not set);
; last request cpu - the %cpu the last request consumed
; it's always 0 if the process is not in Idle state
; because CPU calculation is done when the request
; processing has terminated;
; last request memory - the max amount of memory the last request consumed
; it's always 0 if the process is not in Idle state
; because memory calculation is done when the request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp
; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
; php_value/php_flag - you can set classic ini defines which can
; be overwritten from PHP call 'ini_set'.
; php_admin_value/php_admin_flag - these directives won't be overwritten by
; PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.
; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr/local/php7.0)
; Default Value: nothing is defined by default except the values in php.ini and
; specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f [email protected]
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm-php.www.log
;php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M
5、php.ini文件
我们可以看到 /usr/local/php7.0 安装的目录里边没有 php.ini 配置文件，这就需要我们把源码包的 php.ini 拷贝到我们的安装目录。
拷贝：
# 进入源码包
cd /var/software/php7.0
cp php.ini-development /usr/local/php7.0/etc修改文件名 php.ini-development 为 php.ini：
cd /usr/local/php7.0/etc
mv php.ini-development php.ini这里还有一个坑，就是有时候我们改了php.ini文件后没有生效，这样的问题怎么排查呢？
可以用下边这个命令php -i | grep php.ini来看：
php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/php7.0我们可以看到，最终的执行路径在 /usr/local/php7.0 下面，正常我们是放在 /usr/local/php7.0/etc 下边，编译之后会放在 /usr/local/php7.0 下，所以我们把etc下边的移到 php7.0安装目录下面即可：
root@i:/usr/local/php7.0# mv ./etc/php.ini ./然后再查看：
root@i:/usr/local/php7.0# php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/php7.0
Loaded Configuration File => /usr/local/php7.0/php.ini修改php.ini 默认配置：
#避免暴露php调用mysql的错误信息
display_errors = Off
#开启错误日志
log_errors = On
#错误日志路径
error_log = /var/log/php7.0/php_errors.log
#设置PHP的时区
date.timezone = PRC6、安装扩展
如果扩展在源码包里边有，我们直接在源码包里边进行编译安装即可，如 openssl 扩展包：
源码扩展包：
/var/software/php-7.0.0/extroot@iZ94j7ehy5oZ:/var/software/php-7.0.0/ext# ls -l

如果我们要安装的扩展在源码安装包不存在，则需要在网上下载，然后进行安装，这里以 phpredis扩展为例：
下载：
wget https://github.com/phpredis/phpredis/archive/5.0.0.tar.gz更改名字
mv 5.0.0.tar.gz phpredis-5.0.0.tar.gz解压：
tar -zvx phpredis-5.0.0.tar.gz进入解压目录生成配置文件：
/var/software/# cd phpredis-5.0.0
/var/software/phpredis-5.0.0# /usr/local/php7.0/bin/phpize./configure --with-php-config=/usr/local/php7.0/bin/php-configmake && make install编译成功后，会在/usr/local/php7.0/lib/php/extensions/no-debug-non-zts-20151012/ 目录后，看到新生成的扩展redis.so。
然后在 php.ini 添加扩展
extension_dir="/usr/local/php7.0/lib/php/extensions/no-debug-non-zts-20151012/"
extension=redis.so我们扩展安装OK。
三、Nginx和php-fpm使用
配置Nginx和php-fpm用Sock套接字连接，这里注意路径。
nginx 的配置：
cat /etc/nginx/vhost/blog.conf完整配置：
server {
listen 80;
root /var/www/myblog/public;
index index.php index.html index.htm;
# Make site accessible from http://localhost/
server_name digtime.cn www.digtime.cn;
# ssl-20160924
# rewrite ^/(.*) https://myblog.cn/$1 permanent;
# add_header Access-Control-Allow-Origin *;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
# handle 405 error
# if ($request_method = 'OPTIONS') {
# add_header Access-Control-Allow-Origin *;
# add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,OPTIONS;
# return 204;
#}
try_files $uri $uri/ /index.php?$query_string;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
# 405 error
}
location ~ \.php$ {
try_files $uri /index.php =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/usr/local/php7.0/var/run/php7.0-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
注意：fastcgi_pass 这里使用和我们php-fpm 监听的那里的路径一样：
fastcgi_pass unix:/usr/local/php7.0/var/run/php7.0-fpm.sock;填完这些坑，我们的环境才算搭建成功。
