Centos 6.9 编译安装 LAMP apache 2.4 + Mysql 5.7 + php5.6.34 + Fast-cgi + xcache
实验环境：VMware Workstation Pro 14（试用版）
系统平台：
CentOS release 6.9 (Final) 内核 2.6.32-696.el6.x86_64
Apache/2.4.29 (Unix)
PHP 5.6.34 (cli)
xcache 3.2.01. 编译安装apache 2.4
参考Centos 6.9 apahce 2.4.29编译安装
2. 二进制安装Mysql 5.7
参考CentOS 6.9 自定义单实例 二进制方式 安装mysql5.7.21
3. PHP官网下载Stable版本
http://php.net/downloads.php
# wget http://hk1.php.net/distributions/php-5.6.34.tar.bz24.安装依赖包
有个别包需要EPEL源，可提前配置好Aliyun的Yum源
注意：以下依赖包仅仅限于下面演示的编译参数，实际按需。
#yum install bzip2-devel libxml2-devel libmcrypt-devel libmcrypt curl-devel gd-devel
如果需要后期动态添加模块，还需要安装autoconf
注意：php-7.0以上版本使用--enable-mysqlnd --withmysqli=mysqlnd ，原--with-mysql不再支持
5.编译安装
编译参数
对于mysql的api方法，先了解一下：
PHP5.3以上版本，为了链接MySQL数据库，可以指定mysqlnd，这样在本机就不需要先安装MySQL或MySQL开发包。
mysqlnd从php 5.3开始可用，可以编译时绑定到它（而不用和具体的MySQL客户端库绑定形成依赖）。
从PHP 5.4开始，对于未明确指定--with-mysql的情形，mysql本地驱动将会被安装。
可以参考如下配置：
比如：
--with-mysql > 相当于该参数值为mysqlnd
--with-mysqli > 相当于该参数值为mysqlnd
--with-pdo-mysql > 相当于该参数值为mysqlnd
因为，--with-mysqli=/usr/local/mysql/bin/mysql_config 这种才是明确指定的表示方法
# tar xvf php-5.6.34.tar.bz2
# cd php-5.6.34
./configure --prefix=/usr/local/php-5.6.34 \
--with-openssl \
--enable-mysqlnd \
--with-mysql=/usr/local/mysql \
--with-mysqli \
--with-pdo-mysql \
--enable-mbstring \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir=/usr \
--enable-xml \
--enable-sockets \
--enable-fpm \
--with-mcrypt \
--with-config-file-path=/etc \
--with-config-file-scan-dir=/etc/php.d \
--with-bz2 \
--with-iconv \
--with-gd \
--with-curl \
--disable-debug \
--enable-calendar编译与安装
# make -j 8
出现Build complete. 那么，恭喜编译成功
# make install
以下这些提示，按需。
Wrote PEAR system config file at: /usr/local/php-5.6.34/etc/pear.conf
You may want to add: /usr/local/php-5.6.34/lib/php to your php.ini include_path
/app/httpd/php-5.6.34/build/shtool install -c ext/phar/phar.phar /usr/local/php-5.6.34/bin
ln -s -f phar.phar /usr/local/php-5.6.34/bin/phar
Installing PDO headers: /usr/local/php-5.6.34/include/php/ext/pdo/
创建一个软链接，方便管理版本
#cd /usr/local/
#ln -s php-5.6.34/ php6.复制php配置文件
注意，这些文件是在源码目录里
# cp php.ini-production /etc/php.ini
# cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm
# chmod +x /etc/rc.d/init.d/php-fpm
创建一个存放其他扩展配置的目录
# mkdir /etc/php.d
7.修改php-fpm启动脚本
# vim /etc/rc.d/init.d/php-fpm > 这一步不修改也行，只不过这里是为了后续切换不同版本时方便
prefix=/usr/local/php > 把这行修改为指定的编译路径8.生成php-fpm配置文件
# sed -ri.bak s#php-5.6.34#php#g /usr/local/php/etc/php-fpm.conf.default
# mv /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
# mv /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf > 不用
9.添加php-fpm为启动服务
# chkconfig --add php-fpm
# chkconfig php-fpm on
10.配置httpd支持php
# vim /etc/httpd2.4/httpd.conf
确保以下2条取消注释
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
# 如果使用的是虚拟主机形式，把下面4行添加到主机标签中
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
ProxyRequests Off
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/app/www/virtualhost/$1
其中/app/www/virtualhost指的是站点文件目录
例子：
DocumentRoot "/app/www/virtualhost"
ServerName www.hunk.tech
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
ProxyRequests Off
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/app/www/virtualhost/$1
DirectoryIndex index.php index.html
AllowOverride None
Options None
Require all granted
# service httpd restart
# service php-fpm start10.测试php
#ss -nlt
fcgi正在监听端口
State Recv-Q Send-Q Local Address:Port
LISTEN 0 128 127.0.0.1:9000
编辑一个php的测试文件
#vim /app/www/virtualhost/index.php
11.连接数据库测试
在mysql中创建一个用于连接的账户
mysql> create user test@'192.168.5.102' identified by 'password';
mysql5.7数据库下已经没有password这个字段了，password字段改成了authentication_string
并且密码策略控制着密码相关
以下为修改默认的密码策略，0=LOW，至少8个字符
mysql> set global validate_password_policy=0
测试代码如下：
# vim /app/www/virtualhost/check.php
connect_errno) {
echo "连接失败";
exit();
}
echo "连接成功";
/* close connection */
$mysqli->close();
?>
# curl www.hunk.tech/check.php
连接成功以下代码为判断mysql和mysqli扩展是否安装
The mysql extension is installed.";
} else {
echo "The mysql extension is not installed..
";
}
if (mysqliinstalled()){
echo "The mysqli extension is installed.
";
} else {
echo "The mysqli extension is not installed..
";
}
?>

安装phpize需要的依赖包
#yum install m4 autoconf解压缩xcache-3.2.0.tar.bz2
#tar xvf xcache-3.2.0.tar.gz生成xcanche编译文件
# cd xcache-3.2.0
#/usr/local/php/bin/phpize > 注意，这里指向的是php目录
