CentOS6.x 下 LNMP环境搭建三、安装 PHP

CentOS6.x 下 LNMP环境搭建（准备篇）

CentOS6.x 下LNMP环境搭建（一、安装 MySQL）

CentOS6.x 下LNMP环境搭建（二、安装 Nginx）

CentOS6.x 下LNMP环境搭建（三、安装 PHP）

3.1. 检查 MySQL、Nginx是否正常

# netstat -tlunp

3.2. 检查安装 PHP 所需的 lib 库

# rpm -qa zlib-devel libxm2-devel libjpeg-turbo-devel libpng-devel gd-devel libcurl-devel libxslt-devel freetype-devel
zlib-devel-1.2.3-29.el6.x86_64
# yum -y install zlib-devel libxm2-devel libjpeg-turbo-devel libpng-devel gd-devel libcurl-devel libxslt-devel freetype-devel

注：默认 yum 源没有 libiconv-devel 这个包，需要按照下面的步骤单独编译安装

# cd /root/src
# wget http://ftp.gnu.org/gnu/libiconv/libiconv-1.14.tar.gz
# tar -zxvf libiconv-1.14.tar.gz && cd libiconv-1.14
# ./configure --prefix=/usr/local/libiconv
# make && make install

安装其它额外库
# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
# yum -y install libmcrypt-devel mhash mcrypt

3.3. 安装

# cd /root/src
# tar zxvf php-5.5.36.tar.gz && cd php-5.5.36
# ./configure \
--prefix=/lnmp/server/php5.5.36 \
--with-config-file-path=/lnmp/server/php5.5.36/etc \
--enable-inline-optimization \
--disable-debug \
--disable-rpath \
--enable-shared \
--enable-fpm \
--with-fpm-user=www \
--with-fpm-group=www \
--with-mysql=mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--enable-exif \
--with-gd \
--enable-gd-native-ttf \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--with-gettext \
--with-iconv-dir=/usr/local/libiconv \
--enable-mbstring \
--with-mcrypt \
--with-mhash \
--with-openssl \
--enable-bcmath \
--enable-pcntl \
--enable-shmop \
--enable-sysvsem \
--enable-soap \
--with-libxml-dir \
--enable-sockets \
--with-curl \
--enable-ftp \
--with-zlib-dir \
--enable-zip \
--with-pear

# ln -s /lnmp/server/php5.5.36/ /lnmp/server/php
# ll php.ini*
-rw-r--r-- 1 1001 1001 69236 5月 25 17:36 php.ini-development  <------- 开发模式，更多开启日志、调试信息
-rw-r--r-- 1 1001 1001 69266 5月 25 17:36 php.ini-production  <------- 生产模式
# cp php.ini-production /lnmp/server/php/etc/php.ini

3.4. 配置 PHP 服务（php-fpm 方式）

# cd /lnmp/server/php/etc/
# ls
pear.conf php-fpm.conf.default
# cp php-fpm.conf.default php-fpm.conf
# /lnmp/server/php/sbin/php-fpm   <------- 启动 php-fmp 服务
# ps -ef|grep php-fpm  <------- 查看 php-fpm 启动进程
root    2270   1 0 00:39 ?    00:00:00 php-fpm: master process (/lnmp/server/php5.5.36/etc/php-fpm.conf)
www    2271  2270 0 00:39 ?    00:00:00 php-fpm: pool www
www    2272  2270 0 00:39 ?    00:00:00 php-fpm: pool www
root    2274  2227 0 00:39 pts/0  00:00:00 grep php-fpm
# lsof -i :9000   <------- 查看 php-fpm 默认端口
COMMAND PID USER  FD  TYPE DEVICE SIZE/OFF NODE NAME
php-fpm 2270 root  7u IPv4 12844   0t0 TCP localhost:cslistener (LISTEN)
php-fpm 2271 www  0u IPv4 12844   0t0 TCP localhost:cslistener (LISTEN)
php-fpm 2272 www  0u IPv4 12844   0t0 TCP localhost:cslistener (LISTEN)

设置 php-fpm 启动脚本
# vim /etc/init.d/php-fpm
 复制 php-fpm.sh 中的内容 进去
# chmod 755 /etc/init.d/php-fpm
# service php-fpm start|stop|restart|reload|configtest

3.5. 配置 Nginx 支持 PHP 程序请求访问

server {
  listen    80;
  server_name localhost;
  root  /lnmp/www/;
  index index.html index.htm index.php;

  location ~ .*\.(php|php5)?$ {
    fastcgi_pass  127.0.0.1:9000;
    fastcgi_index index.php;
    include    fastcgi.conf;
  }
}
