拷贝配置文件

# cp php.ini-production /usr/local/php/etc/php.ini

编辑php.ini，找到date.timezone，将前面的注释去掉，改为date.timezone = PRC，否则php -i | grep configure查看编译参数报警告如下

PHP Warning: Unknown: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in Unknown on line 0

隐藏php版本信息

# sed -i 's/expose_php = On/expose_php = Off/' /usr/local/php/etc/php.ini

拷贝启动脚本

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

设置php-fpm开机启动

# chkconfig php-fpm on

设置php环境变量

# vim /etc/profile

在其文件末尾添加如下变量

export PATH=$PATH:/usr/local/php/bin
export PATH=$PATH:/usr/local/php/sbin

或者用以下命令添加

# sed -i '/unset -f pathmunge/a\export PATH=$PATH:/usr/local/php/bin' /etc/profile
# sed -i '/unset -f pathmunge/a\export PATH=$PATH:/usr/local/php/sbin' /etc/profile

运行如下命令使环境变量生效

# source /etc/profile
