编译安装PHP

下载 PHP 源码包

# wget http://cn2.php.net/distributions/php-5.6.0.tar.xz
# xz -d php-5.6.0.tar.xz
# tar xf php-5.6.0.tar -C /usr/local/src/

添加 epel 源

# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

安装依赖

# yum install gcc bison bison-devel zlib-devel libmcrypt-devel mcrypt mhash-devel openssl-devel libxml2-devel libcurl-devel bzip2-devel readline-devel libedit-devel sqlite-devel

注：如果需要直接安装gd库，需要以下扩展

yum -y install gd gd2 gd-devel gd2-devel zlib freetype

注：如果你使用的 epel 7 的源，可能会没有 mcrypt mhash mhash-devel 几个包，在 http://dl.fedoraproject.org/pub/epel/6/x86_64/ 中下载，使用 yum localinstall xxx.rpm 或 rpm -Uvh xxx.rpm 手动安装即可。

创建 www 用户

# groupadd www
# useradd -g www -s /sbin/nologin -M www

编译安装

# cd /usr/local/src/php-5.6.0/

# ./configure 
--prefix=/usr/local/php56 
--with-config-file-path=/usr/local/php56/etc 
--enable-inline-optimization 
--disable-debug 
--disable-rpath 
--enable-shared 
--enable-opcache 
--enable-fpm 
--with-fpm-user=www 
--with-fpm-group=www 
--with-mysql=mysqlnd 
--with-mysqli=mysqlnd 
--with-pdo-mysql=mysqlnd 
--with-gettext 
--enable-mbstring 
--with-iconv 
--with-mcrypt 
--with-mhash 
--with-openssl 
--enable-bcmath 
--enable-soap 
--with-libxml-dir 
--enable-pcntl 
--enable-shmop 
--enable-sysvmsg 
--enable-sysvsem 
--enable-sysvshm 
--enable-sockets 
--with-curl 
--with-zlib 
--enable-zip 
--with-bz2 
--with-readline
//需要gd库扩展，需添加以下参数
-with-png-dir --with-freetype-dir --with-jpeg-dir=/usr/local/jpeg -with-zlib-dir --with-gd

配置 PHP

# cp php.ini-development /usr/local/php56/etc/php.ini

php-fpm 服务

# cp /usr/local/php56/etc/php-fpm.conf.default /usr/local/php56/etc/php-fpm.conf
# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm56
# chmod +x /etc/init.d/php-fpm56

启动 php-fpm

# service php-fpm56 start
Starting php-fpm  done

php-fpm 可用参数 start|stop|force-quit|restart|reload|status

添加 PHP 命令到环境变量

编辑 ~/.bash_profile，将：

PATH=$PATH:$HOME/bin
改为：
PATH=$PATH:$HOME/bin:/usr/local/php56/bin

使 PHP 环境变量生效：

# . ~/.bash_profile

查看看 PHP 版本

# php -v

鉴于有些老铁忘记加上gd扩展，以下附上gd单独编译扩展
