安装php

下载地址：https://www.php.net/ ，这里用的是7.1.10版本。

• 先下载依赖包

  yum -y install \
  libjpeg \
  libjpeg-devel \
  libpng libpng-devel \
  freetype freetype-devel \
  libxml2 \
  libxml2-devel \
  zlib zlib-devel \
  curl curl-devel \
  openssl openssl-devel
  

• 将下载包解压然后进入文件夹中执行

  [root@server php-7.1.10]# pwd
  /opt/php-7.1.10
  ./configure \
  --prefix=/usr/local/php \  //PHP文件路径
  --with-mysql-sock=/usr/local/mysql/mysql.sock \ //对接mysql通讯文件
  --with-mysqli \     //with支持的各项功能
  --with-zlib \
  --with-curl \
  --with-gd \
  --with-jpeg-dir \
  --with-png-dir \
  --with-freetype-dir \
  --with-openssl \
  --enable-fpm \				//开启fpm模块
  --enable-mbstring \			//开启多字段模块
  --enable-xml \				//开启扩展性标记语言模块
  --enable-session \ 			//开启会话
  --enable-ftp \				//开启文本传输协议
  --enable-pdo \				//开启函数库
  --enable-tokenizer \		//开启令牌解释器
  --enable-zip				//开启zip压缩
  

• 编译

  make && make install
  

• 将php核心配置文件复制到php/lib下面

  [root@server php-7.1.10]# cp php.ini-development /usr/local/php/lib/php.ini
  

  修改核心配置文件内容

  vim /usr/local/php/lib/php.ini
  939 date.timezone = Asia/Shanghai 	//设置时区
  1170 mysqli.default_socket = /usr/local/mysql/mysql.sock   		//设置mysql通讯文件的对接
  

• 验证安装的模块

  [root@server etc]# /usr/local/php/bin/php -m

• 优化fpm模块，将进程配置文件和扩展配置文件进行拷贝

  cd /usr/local/php/etc/
  cp php-fpm.conf.default php-fpm.conf
  cd /usr/local/php/etc/php-fpm.d/
  cp www.conf.default www.conf
  

• 配置进程配置文件，开启pid

• 

• 启动php-fpm -c，查看是否启动和进程号

  [root@server etc]# /usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini
  [root@server etc]# netstat -antp | grep 9000
  tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      29883/php-fpm: mast 
  [root@server etc]# ps aux | grep -c "php-fpm"
  4

  进入nginx配置文件中修改，将注释去掉，实现nginx与php对接

•  65         location ~ \.php$ {
   66             root           html;
   67             fastcgi_pass   127.0.0.1:9000;
   68             fastcgi_index  index.php;
   69             fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
   70             include        fastcgi_params;
   71         }
  
  

  编写一个php主页

• vim /usr/local/nginx/html/index.php
  <?php
  phpinfo();
  ?>

  访问页面

• 测试一下数据库是否工作正常，先进入数据库给用户提权

  mysql -uroot -p123
  mysql> create database bbs;
  Query OK, 1 row affected (0.00 sec)
  
  mysql> grant all on bbs.* to 'bbsuser'@'%' identified by 'admin123';
  Query OK, 0 rows affected, 1 warning (0.01 sec)
  
  mysql> grant all on bbs.* to 'bbsuser'@'localhost' identified by 'admin123';
  Query OK, 0 rows affected, 1 warning (0.00 sec)
  
  mysql> flush privileges;
  Query OK, 0 rows affected (0.00 sec)

• 重新编写php主页

  <?php
  $link=mysqli_connect('12.0.0.8','bbsuser','admin123');
  if($link) echo "<h1>Success</h1>";
  else echo "Fail";
  ?>

  

• 对接成功
