Steps to install Nginx in yum mode under CentOS7

Nginx is a powerful, high-performance Web and reverse proxy server with a number of excellent features. Low overhead, high concurrency, support for caching, support for forward and backward proxies, support for load balancing, support for regularization, support for rewrite, etc. So the fans are numerous. This article briefly describes the installation and deployment of yum based on CentOS 7 for your reference.

If it is a compiled installation, please refer to: Linux 6 for installation

For common configuration of Nginx, see: Overview of Nginx and daily administration

1. Configure nginx yum source 


 The demo environment 
[root@centos7-router ~]# more /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)

[root@centos7-router ~]# vim /etc/yum.repos.d/nginx.repo

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1

 Will be in the above configuration file OS Replace with rhel or centos . OSRELEASE Replace with 6 or 7 Which is the current Linux for 6 or 7 version 

 Look at the machine ip
[root@centos7-router ~]# ip addr|grep inet|grep global
inet 172.24.8.254/24 brd 172.24.8.255 scope global eno16777728
inet 192.168.1.175/24 brd 192.168.1.255 scope global dynamic eno33554960

[root@centos7-router ~]# yum install nginx -y

[root@centos7-router ~]# ss -nltp|grep nginx
LISTEN 0 128 *:80 *:* users:(("nginx",pid=65418,fd=6),("nginx",pid=65415,fd=6))

 To view nginx The version of the 
[root@centos7-router ~]# nginx -v
nginx version: nginx/1.12.2

 View or modify the configuration file 
[root@centos7-router ~]# more /etc/nginx/nginx.conf

user nginx;

access_log /var/log/nginx/access.log main;

sendfile on;
#tcp_nopush on;

#gzip on;

include /etc/nginx/conf.d/*.conf;
}

[root@centos7-router ~]# firewall-cmd --add-service=http --permanent
