添加 nginx源

nginx的镜像仓库地址:http://nginx.org/packages/

1.将nginx放到yum repro库中

rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

• 1

2.查看包的信息

yum info nginx

• 1

3.安装 nginx

yum install nginx

• 1

4.启动nginx
我这个是在docker的环境里面，直接使用nginx就完成了启动

#直接启动nginx
nginx

#物理机
service nginx start

5.查看nginx版本

nginx -v

6.查看nginx首页信息

 curl localhost

nginx常用操作

启动:

$ /usr/sbin/nginx或任意路径下运行service nginx start(centos7是systemctl start nginx.service )

#也可以直接输入nginx
nginx
#在service 中
service nginx start

重启：

nginx -s reload

停止：

nginx -s stop

测试配置文件是否正常：

nginx –t

nginx配置文件default.conf

#编辑nginx的配置文件
 vi /etc/nginx/conf.d/default.conf

配置负载均衡服务器：

vi /etc/nginx/nginx.conf

#Nginx创建进程所用用户和用户组  
    #user  nobody;  
    user  test  test;  
    #进程数，一般等于CPU数量  
    worker_processes  4;  


    #错误日志，定义到warn级别比较合适  
    #error_log  logs/error.log;  
    error_log  logs/error.log  warn;  


    #指定pid存放文件  
    pid        logs/nginx.pid;  

    events {  
        #使用网络IO模型linux建议epoll，FreeBSD建议采用kqueue  
        use epoll;  

        #允许最大连接数  
        worker_connections  1024;  
    }  

    http {  
        include       mime.types;  
        default_type  application/octet-stream;  

        #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '  
        #                  '$status $body_bytes_sent "$http_referer" '  
        #                  '"$http_user_agent" "$http_x_forwarded_for"';  

        #关闭日志能够减少IO，但是建议开启error_log warn级别  
        #access_log  logs/access.log  main;  

        sendfile        on;  
        #tcp_nopush     on;

        keepalive_timeout  30;
