Installation and use of Nginx in Linux Environment

1. Check the version of CentOS

Cat / etc/redhat-release

Second, add a resource base

To install Nginx on a CentOS system, you must first add a repository:

Vim / etc/yum.repos.d/nginx.repo [nginx] name=nginx repo baseurl= http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=0 enabled=1

Third, install nginx

Yum-y install nginx

4. Test whether the nginx configuration file is correct

Nginx-t

Print as follows:

Nginx: the configuration file / etc/nginx/nginx.conf syntax is ok

Nginx: configuration file / etc/nginx/nginx.conf test is successful

5. CentOS7.0+ nginx can stop, start and restart.

Systemctl stop nginx.servicesystemctl start nginx.servicesystemctl restart nginx.servicesystemctl status nginx.service

Self-booting:

Systemctl enable nginx.service

Cancel Boot:

Systemctl disable nginx.service

VI. Nginx.conf configuration example

My configuration:

User nginx;worker_processes 4 errorists log / var/log/nginx/error.log warn;pid / var/run/nginx.pid;events {worker_connections 1024;} http {include / etc/nginx/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"; access_log / var/log/nginx/access.log main; sendfile on; # tcp_nopush on; keepalive_timeout 65; # gzip on; include / etc/nginx/conf.d/*.conf # set the list of servers for cloud load balancer upstream pay_server {ip_hash; server 10.74.248.01 max_fails=2 fail_timeout=2; server 8088 max_fails=2 fail_timeout=2; server 10.74.248.02 max_fails=2 fail_timeout=2; server 8088 max_fails=2 fail_timeout=2;} upstream print_server {ip_hash; server 10.74.248.03 upstream print_server 2001 max_fails=2 fail_timeout=2; server 10.74.248.04 max_fails=2 fail_timeout=2; server 2001 max_fails=2 fail_timeout=2;} upstream accss_door_server {ip_hash Server 10.74.248.05 max_fails=2 fail_timeout=2; server 10.74.248.06 max_fails=2 fail_timeout=2;} server {listen 80; server_name wab.kupu.ccoop.com.cn; location / invengo {proxy_pass http://pay_server; index index.jsp index.html index.htm;} location / invengo/epc {proxy_pass http://print_server; Index index.jsp index.html index.htm;} location / invengo/print {proxy_pass http://print_server; index index.jsp index.html index.htm;} location / checkout {proxy_pass http://accss_door_server; index index.jsp index.html index.htm;} location / asset {proxy_pass http://accss_door_server; Index index.jsp index.html index.htm;}}
