2 安装PHP 5.2.14（FastCGI模式）

1）编译安装PHP 5.2.14所需的支持库：

?

2）编译安装MySQL 5.5.3-m3

?

1 2 3 4 5 6 7 8 9

/usr/sbin/groupadd mysql /usr/sbin/useradd -g mysql -s  /sbin/nologin mysql tar zxvf mysql-5.5.3-m3. tar .gz cd mysql-5.5.3-m3/ . /configure --prefix= /usr/local/mysql/ -- enable -assembler --with-extra-charsets=complex -- enable -thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server -- enable - local -infile --with-plugins=partition,innobase,myisammrg make &&  make install chmod +w  /usr/local/mysql chown -R mysql:mysql  /usr/local/mysql cd ../

附：以下为附加步骤，如果你想在这台服务器上运行 MySQL数据库，则执行以下几步。如果你只是希望让PHP支持MySQL扩展库，能够连接其他服务器上的MySQL数据库，那么，以下两步无需执行。

①、创建MySQL数据库存放目录

?

1 2 3 4

mkdir -p  /var/mysql/data/ mkdir -p  /var/mysql/binlog/ mkdir -p  /var/mysql/relaylog/ chown -R mysql:mysql  /var/mysql/

②、以mysql用户帐号的身份建立数据表：

?

1 2	/usr/local/mysql/bin/mysql_install_db --basedir= /usr/local/mysql --datadir= /var/mysql/data --user=mysql /usr/local/mysql/bin/mysql_install_db --basedir= /usr/local/mysql --datadir= /var/mysql/data --user=mysql

③、创建my.cnf配置文件：

?

1	vi /var/mysql/my .cnf

启动MySQL：

?

1	/usr/local/mysql/bin/mysqld_safe --user=root

输入以下 SQL语句，创建一个具有 root权限的用户（admin）和密码（12345678）：

?

1 2 3

GRANT ALL PRIVILEGES ON *.* TO  'admin' @ 'localhost' IDENTIFIED BY  '12345678' ; GRANT ALL PRIVILEGES ON *.* TO  'admin' @ '127.0.0.1' IDENTIFIED BY  '12345678' ; GRANT ALL PRIVILEGES ON *.* TO  'root' @ '%' IDENTIFIED BY  'root' ;

MYSQL启动脚本

?

1	vi /var/mysql/mysql

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43

#!/bin/sh   mysql_port=3306 mysql_username= "root" mysql_password= "root"   function_start_mysql() {      printf "Starting MySQL...\n"      /usr/local/mysql/bin/mysqld_safe --defaults- file = /var/mysql/my .cnf 2>&1 >  /var/mysql/binlog/start .log &   }   function_stop_mysql() {      printf "Stoping MySQL...\n"      /usr/local/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S  /tmp/mysql .sock  shutdown }   function_restart_mysql() {      printf "Restarting MySQL...\n"      function_stop_mysql      sleep 5      function_start_mysql }   function_kill_mysql() {      kill -9 $( ps -ef & #124; grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')      kill -9 $( ps -ef & #124; grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}') }   if [  "$1" =  "start" ];  then      function_start_mysql elif [  "$1" =  "stop" ];  then      function_stop_mysql elif [  "$1" =  "restart" ];  then function_restart_mysql elif [  "$1" =  "kill" ];  then function_kill_mysql else      printf "Usage: /var/mysql/mysql {start|stop|restart|kill}\n" fi

php安装

4）编译安装PHP5扩展模块

?

1 2 3 4 5 6 7

tar zxvf memcache-2.2.5.tgz cd memcache-2.2.5/ /usr/local/php/bin/phpize . /configure --with-php-config= /usr/local/php/bin/php-config make make install cd ../

1、安装Nginx所需的pcre库：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

tar zxvf pcre-8.10. tar .gz cd pcre-8.10/ . /configure make &&  make install cd ../     tar jxvf eaccelerator-0.9.6.1. tar .bz2 cd eaccelerator-0.9.6.1/ /usr/local/php/bin/phpize . /configure -- enable -eaccelerator=shared --with-php-config= /usr/local/php/bin/php-config make make install cd ../   tar zxvf PDO_MYSQL-1.0.2.tgz cd PDO_MYSQL-1.0.2/ /usr/local/php/bin/phpize . /configure --with-php-config= /usr/local/php/bin/php-config --with-pdo-mysql= /usr/local/mysql make make install cd ../   tar zxvf ImageMagick. tar .gz cd ImageMagick-6.5.1-2/ . /configure make make install cd ../   tar zxvf imagick-2.3.0.tgz cd imagick-2.3.0/ /usr/local/php/bin/phpize . /configure --with-php-config= /usr/local/php/bin/php-config make make install cd ../

5）修改php.ini文件

手工修改：查找/usr/local/php/etc/php.ini中的extension_dir = "./" 　 
修改为extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/" 
并在此行后增加以下几行，然后保存：

?

1 2 3

extension =  "memcache.so" extension =  "pdo_mysql.so" extension =  "imagick.so"

再查找output_buffering = Off 修改为output_buffering = On 　　 
再查找; cgi.fix_pathinfo=0 　　修改为cgi.fix_pathinfo=0， 
防止Nginx文件类型错误解析漏洞。 
注：若嫌手工修改麻烦，可执行以下shell命令，自动完成对php. ini文件的修改： 

?

1 2 3 4

sed -i  's#extension_dir = "./"#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /usr/local/php/etc/php .ini sed -i  's#output_buffering = Off#output_buffering = On#' /usr/local/php/etc/php .ini sed -i  "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/php/etc/php .ini sed -i  "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/php/etc/php .ini

7）创建www用户和组，以及供book.zhiyin.com和www.zhiyin.com两个虚拟主机使用的目录：

?

1 2 3 4 5 6 7 8 9 10

/usr/sbin/groupadd www /usr/sbin/useradd -g www www mkdir -p  /var/webroot/log chmod +w  /var/webroot/log chown -R www:www  /var/webroot/log mkdir -p  /var/webroot/web chmod +w  /var/webroot/web chown -R www:www  /var/webroot/web   chown -R admin:ftpgroup  /var/webroot/web

8） 创建Nginx日志目录

?

1 2 3

mkdir -p  /var/log/nginx chmod +w  /var/log/nginx chown -R www:www  /var/log/nginx

4） 创建Nginx配置文件

①在/usr/local/nginx/conf/目录中创建nginx.conf文件：

?

1 2	rm -f  /usr/local/nginx/conf/nginx .conf vi /usr/local/nginx/conf/nginx .conf

输入以下内容：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161

②、在/usr/local/nginx/conf/目录中创建fcgi.conf文件：

?

1	vi /usr/local/nginx/conf/fcgi .conf

　输入以下内容：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

#fastcgi_param  GATEWAY_INTERFACE  CGI/1.1; #fastcgi_param  SERVER_SOFTWARE    nginx;   fastcgi_param  QUERY_STRING       $query_string; fastcgi_param  REQUEST_METHOD     $request_method; fastcgi_param  CONTENT_TYPE       $content_type; fastcgi_param  CONTENT_LENGTH     $content_length;   fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name; fastcgi_param  SCRIPT_NAME        $fastcgi_script_name; fastcgi_param  REQUEST_URI        $request_uri; fastcgi_param  DOCUMENT_URI       $document_uri; fastcgi_param  DOCUMENT_ROOT      $document_root; fastcgi_param  SERVER_PROTOCOL    $server_protocol;   fastcgi_param  REMOTE_ADDR        $remote_addr; fastcgi_param  REMOTE_PORT        $remote_port; fastcgi_param  SERVER_ADDR        $server_addr; fastcgi_param  SERVER_PORT        $server_port; fastcgi_param  SERVER_NAME        $server_name;   # PHP only, required if PHP was built with --enable-force-cgi-redirect fastcgi_param  REDIRECT_STATUS    200;

5）启动Nginx

?

1 2	ulimit -SHn 65535 /usr/local/nginx/sbin/nginx

4 配置开机自动启动Nginx + PHP

?

1	vi /etc/rc . local

在末尾增加以下内容：

?

1 2 3 4

ulimit -SHn 65535 /usr/local/php/sbin/php-fpm start /usr/local/nginx/sbin/nginx /var/mysql/mysql start

5 在不停止Nginx服务的情况下平滑变更Nginx配置

1）修改

/usr/local/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：

?

1	/usr/local/nginx/sbin/nginx -t

如果屏幕显示以下两行信息，说明配置文件正确：

the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully

2） 平滑重启：

①、对于Nginx 0.8.x版本，现在平滑重启Nginx配置非常简单，执行以下命令即可：

?

1	/usr/local/nginx/sbin/nginx -s reload

②、对于Nginx 0.8.x之前的版本，平滑重启稍微麻烦一些，按照以下步骤进行即可。输入以下命令查看Nginx主进程号：

?

1	ps -ef |  grep "nginx: master process" |  grep - v "grep" |  awk -F  ' ' '{print $2}'

屏幕显示的即为Nginx主进程号，例如： 　　6302 这时，执行以下命令即可使修改过的Nginx配置文件生效：

?

1	kill -HUP 6302

或者无需这么麻烦，找到Nginx的Pid文件：

?

1	kill -HUP ` cat /usr/local/nginx/nginx .pid`

6 优化Linux内核参数 (此处内容不推荐使用)

?

1	vi /etc/sysctl .conf

在末尾增加以下内容：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

# Add net.ipv4.tcp_max_syn_backlog = 65536 net.core.netdev_max_backlog =  32768 net.core.somaxconn = 32768   net.core.wmem_default = 8388608 net.core.rmem_default = 8388608 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216   net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_syn_retries = 2   net.ipv4.tcp_tw_recycle = 1 #net.ipv4.tcp_tw_len = 1 net.ipv4.tcp_tw_reuse = 1   net.ipv4.tcp_mem = 94500000 915000000 927000000 net.ipv4.tcp_max_orphans = 3276800   #net.ipv4.tcp_fin_timeout = 30 #net.ipv4.tcp_keepalive_time = 120 net.ipv4.ip_local_port_range = 1024  65535

使配置立即生效：

 

 

?

1	/sbin/sysctl -p

引用来自“mark35”的答案

之所以YUM安装的PHP会有那么多 --disable参数，那是为了你以后单独安装部件考虑的。你可以通过 YUM install php-??? 来安装需要部件，比如

?

1	yum  install php-mysql php-gd

相当于只安装了PHP核心，扩展包按需安装

 

可是我执行了

?

1	yum  install php-mysql
