1.安装nginx

yum install yum-priorities -y
wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm
yum install nginx

systemctl start nginx.service #启动nginx
systemctl stop nginx.service #停止
systemctl restart nginx.service #重启
systemctl enable nginx.service #设置开机启动

2.更改nginx端口号（根据自己需求）

cd /etc/nginx/conf.d/
vim default.conf
把listen 80改成listen 81

systemctl restart nginx.service #重启nginx

3.访问http://ip:81即可看到nginx首页

4.下一步安装 php-fpm

yum install php-fpm

systemctl start php-fpm.service #启动php-fpm
systemctl enable php-fpm.service #设置开机启动

5.更改nginx配置文件识别php

 vi /etc/nginx/conf.d/default.conf，把之前的#给去掉就可以了，顺手改一下fastcgi_param

location ~ \.php$ {
    root           html;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/$fastcgi_script_name;
    include        fastcgi_params;
}

6.

在 /usr/share/nginx/html中新建一个test.php  <?php echo 123;?>

访问http://ip:81/test.php即可看到nginx中的php页面

7.负载配置

[python] view plain copy

upstream site{
        server 172.16.170.138;
        server 172.16.170.139;
}
server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
        proxy_pass http://site;
    }
