3.yum安装mysql

点击查看代码

[root@localhost nginx]#  tee /etc/yum.repos.d/mysql.repo <<EOF      //官方源
> [mysql57-community]
> name=MySQL 5.7 Community Server
> baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/

4.编译安装php

点击查看代码

`1、安装环境依赖包`
[root@localhost ~]#  yum -y install gd \    //安装依赖环境
> libjpeg libjpeg-devel \
> libpng libpng-devel \
> freetype freetype-devel \
> libxml2 libxml2-devel \
> zlib zlib-devel \
> curl curl-devel \
> openssl openssl-devel


`2、编译安装`
[root@localhost ~]#  cd /opt
[root@localhost opt]#  rz

[root@localhost opt]#  ls
Discuz_X3.4_SC_UTF8.zip  nginx-1.22.0  nginx-1.22.0.tar.gz  php-7.1.10.tar.bz2  rh
[root@localhost opt]#  tar xf php-7.1.10.tar.bz2   //解压
[root@localhost opt]#  ls
Discuz_X3.4_SC_UTF8.zip  nginx-1.22.0  nginx-1.22.0.tar.gz  php-7.1.10  php-7.1.10.tar.bz2  rh

[root@localhost opt]#  cd php-7.1.10/
[root@localhost php-7.1.10]#  ./configure \
> --prefix=/usr/local/php \
> --with-mysql-sock=/usr/local/mysql/mysql.sock \
> --with-mysqli \
> --with-zlib \
> --with-curl \

> --enable-zip
[root@localhost php-7.1.10]#  make -j2 && make install


`3、路径优化`
[root@localhost php-7.1.10]#  ln -s /usr/local/php/bin/* /usr/local/bin/ 
[root@localhost php-7.1.10]#  ln -s /usr/local/php/sbin/* /usr/local/sbin/

`4、调整PHP配置文件`
php有三个配置文件： 
php.ini		主配置文件  
php-fpm.conf	进程服务配置文件 
www.conf          扩展配置文件


修改主配置文件
[root@localhost php-7.1.10]#  cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini
[root@localhost php-7.1.10]#  vim /usr/local/php/lib/php.ini  
 939 date.timezone = Asia/Shanghai                       //修改时区
1170 mysqli.default_socket = /var/lib/mysql/mysql.sock   //指明mysql文件位置

修改进程服务配置文件
[root@localhost php-7.1.10]#  cd /usr/local/php/etc/
[root@localhost etc]#  ls
pear.conf  php-fpm.conf.default  php-fpm.d
[root@localhost etc]#  cp  php-fpm.conf.default php-fpm.conf
[root@localhost etc]#  vim php-fpm.conf
 17 pid = run/php-fpm.pid    //去掉";"注释

修改扩展配置文件
[root@localhost etc]#  cd /usr/local/php/etc/php-fpm.d/
[root@localhost php-fpm.d]#  ls
www.conf.default
[root@localhost php-fpm.d]#  cp www.conf.default www.conf
[root@localhost php-fpm.d]#  ls
www.conf  www.conf.default

`5、启动php-fpm`
[root@localhost php-fpm.d]#  cd /opt/php-7.1.10/sapi/fpm
[root@localhost fpm]#  cp php-fpm.service /usr/lib/systemd/system/php-fpm.service
[root@localhost fpm]#  systemctl daemon-reload 
[root@localhost fpm]#  systemctl start php-fpm.service 

[root@localhost fpm]#  ss -natp |grep 9000
LISTEN     0      128    127.0.0.1:9000                     *:*                   users:(("php-fpm",pid=15127,fd=0),("php-fpm",pid=15126,fd=0),("php-fpm",pid=15125,fd=6))

5.配置nginx支持php解析
修改主配置文件

点击查看代码

[root@localhost fpm]#  vim /usr/local/nginx/conf/nginx.conf
 
 45             index  index.html index.htm index.php;
 .................
 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;    //注意路径！
 70             include        fastcgi_params;
 71         }
 
[root@localhost fpm]#  nginx -s reload

验证php测试页

点击查看代码

[root@localhost fpm]#  cd /usr/local/nginx/html/
[root@localhost html]#  ls
50x.html  index.html

[root@localhost html]#  vim index.php   //编辑一个测试页面
<?php
phpinfo();
?>
[root@localhost html]#  nginx -s reload

浏览器中输入192.168.204.40/index.php进行验证

验证数据库工作是否正常

点击查看代码

[root@localhost html]#  mysql -u root -p"abc123"

CREATE DATABASE bbs;
GRANT all ON bbs.* TO 'bbsuser'@'%' IDENTIFIED BY 'admin123';
GRANT all ON bbs.* TO 'bbsuser'@'localhost' IDENTIFIED BY 'admin123';
flush privileges;

修改测试页内容

点击查看代码

[root@localhost html]#  vim /usr/local/nginx/html/index.php

<?php
$link=mysqli_connect('192.168.204.40','bbsuser','admin123');   //注意ip地址
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>

[root@localhost html]#  nginx -s reload

浏览器中输入192.168.204.40/index.php进行验证
