一、查看linux系统版本

cat /etc/redhat-release

二、安装Nginx

 1.添加Nginx到yun源

sudo rpm -Uvh nginx.org/packages/ce… 2.安装Nginx

sudo yum install -y nginx

3.启动Nginx

sudo systemctl start nginx.service

4.访问使用本机IP地址在浏览器访问，如果出现如下界面表示安装成功

5.开机启动Nginx

sudo systemctl enable nginx.service 三、Nginx配置

  1.nginx网站默认存放目录路径

/usr/share/nginx/html 2.网站默认站点配置路径

/etc/nginx/conf.d/default.conf 3.自定义Nginx站点配置文件存放目录

     3.1 新建我自己存放nginx配置文件目录

         /home/jysoft/nginx/conf.d

     3.2 在3.1目录下新建default.conf文件，用与存放自己配置文件,配置文件内容如下

server { listen 80; server_name 112.112.112.112; proxy_redirect off; client_max_body_size 30m; client_body_buffer_size 128k; proxy_connect_timeout 1200; proxy_send_timeout 1200; proxy_read_timeout 1200; proxy_buffer_size 4k; proxy_buffers 32 4k; proxy_busy_buffers_size 64k; proxy_set_header Host $host:$ server_port; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For$ proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Scheme $scheme;

 location /tm10080/ {
       proxy_pass    http://127.0.0.1:10080/tm10080/;
       proxy_redirect default ;
    }

} 4. 加载自定义nginx配置文件

   4.1    vi /etc/nginx/nginx.conf

            include     /home/jysoft/nginx/conf.d/*.conf;

4.2 退出保存

  按 esc 键      再   :wq      即可保存退出

4.3 检验nginx配置文件中有没有错误

   nginx -t

四、关闭Linux内SELinux（不关闭nginx代理不能正常生效）

vi /etc/selinux/config

将SELINUX=enforcing改为SELINUX=disabled

重启机器即可，重启命令如下

shutdown -r now 五、卸载Nginx

1.首先输入命令 ps -ef | grep nginx检查一下nginx服务是否在运行。

[root@localhost /]# ps -ef |grep nginx root 3163 2643 0 14:08 tty1 00:00:00 man nginx root 5427 1 0 14:50 ? 00:00:00 nginx: master process nginx nginx 5428 5427 0 14:50 ? 00:00:00 nginx: worker process root 5532 2746 0 14:52 pts/0 00:00:00 grep --color=auto nginx 2.停止Nginx服务

[root@localhost /]# /usr/sbin/nginx -s stop [root@localhost /]# netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1/systemd
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1261/sshd
tcp6 0 0 :::111 :::* LISTEN 1/systemd
tcp6 0 0 :::22 :::* LISTEN 1261/sshd 3.查找、删除Nginx相关文件

查看Nginx相关文件：whereis nginx

[root@localhost /]# whereis nginx nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man8/nginx.8.gz /usr/share/man/man3/nginx.3pm.gz find查找相关文件

[root@localhost /]# find / -name nginx /usr/lib64/perl5/vendor_perl/auto/nginx /usr/lib64/nginx /usr/share/nginx /usr/sbin/nginx /etc/logrotate.d/nginx /etc/nginx /var/lib/nginx /var/log/nginx 依次删除find查找到的所有目录：rm -rf /usr/sbin/nginx

4.再使用yum清理

[root@localhost /]# yum remove nginx 依赖关系解决
