一、查看CentOS的版本
cat /etc/redhat-release
二、添加資源庫
在 CentOS 系統上安裝 Nginx ，得先去添加一個資源庫：
vim /etc/yum.repos.d/nginx.repo [nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=0 enabled=1
三、安裝nginx
yum -y install nginx
四、測試nginx配置文件是否正確
nginx -t
打印如下：
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
五、CentOS7.0+ nginx實現停止、啟動、重啟
systemctl stop nginx.service systemctl start nginx.servicesystemctl restart nginx.servicesystemctl status nginx.service
開機自啟：
systemctl enable nginx.service
取消開機自啟：
systemctl disable nginx.service
六、nginx.conf配置示例
我的配置：
user nginx;worker_processes 4;error_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; #設定負載均衡的服務器列表 upstream pay_server { ip_hash; server 10.74.248.01:8088 max_fails=2 fail_timeout=2; server 10.74.248.02:8088 max_fails=2 fail_timeout=2; } upstream print_server { ip_hash; server 10.74.248.03:2001 max_fails=2 fail_timeout=2; server 10.74.248.04:2001 max_fails=2 fail_timeout=2; } upstream accss_door_server { ip_hash; server 10.74.248.05:2002 max_fails=2 fail_timeout=2; server 10.74.248.06:2002 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; } }常用的nginx.conf配置：
