nginx安装及启动

1.用yum源安装，首先配置yum源 在“/etc/yum.repo.d/”下创建yum源文件

例如：cd /etc/yum.repo.d/nginx.repo

  [nginx-stable]

name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

2.查看yum源包

　　yum info nginx 查看nginx安装包源信息版本等

　　yum install nginx  安装yum源安装包

　　安装完成后用"nginx -h" 查看nginx应用的命令

[root@192 ~]# nginx -h
nginx version: nginx/1.16.1
Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:
  -?,-h         : this help
  -v            : show version and exit
  -V            : show version and configure options then exit
  -t            : test configuration and exit
  -T            : test configuration, dump it and exit
  -q            : suppress non-error messages during configuration testing
  -s signal     : send signal to a master process: stop, quit, reopen, reload
  -p prefix     : set prefix path (default: /etc/nginx/)
  -c filename   : set configuration file (default: /etc/nginx/nginx.conf)
  -g directives : set global directives out of configuration file

3.用"nginx"命令启动nginx服务

   启动服务后用命令ss -ntlp查看端口和服务的情况

[root@192 ~]# ss -ntlp

4.再开通防火墙和80端口即可

 firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload

5用其他主机访问IP地址即可
