linux下安装nginx及负载配置

1.安装nginx

[python]  view plain  copy

 

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

[python]  view plain  copy

 

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

2.更改nginx端口号（根据自己需求）

[python]  view plain  copy

 

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

[python]  view plain  copy

 

1. 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

[python]  view plain  copy

 

1. yum install php-fpm  

[python]  view plain  copy

 

1. systemctl start php-fpm.service #启动php-fpm  
2. 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

[python]  view plain  copy

 

1. location ~ \.php$ {  
2.     root           html;  
3.     fastcgi_pass   127.0.0.1:9000;  
4.     fastcgi_index  index.php;  
5.     fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/$fastcgi_script_name;  
6.     include        fastcgi_params;  
7. }  

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

 

1. upstream site{  
2.         server 172.16.170.138;  
3.         server 172.16.170.139;  
4. }  
5. server {  
6.     listen       80;  
7.     server_name  localhost;  
8.   
9.     #charset koi8-r;  
10.     #access_log  /var/log/nginx/log/host.access.log  main;  
11.   
12.     location / {  
13.         root   /usr/share/nginx/html;  
14.         index  index.html index.htm;  
15.         proxy_pass http://site;  
16.     }
