五、CentOS7.0+ nginx实现停止、启动、重启

systemctl stop nginx.service 
systemctl start nginx.service
systemctl restart nginx.service
systemctl status nginx.service

开机自启：

systemctl enable nginx.service

取消开机自启：

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;

 #设定负载均衡的服务器列表
 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：

user www www;
worker_processes 2;
error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
pid logs/nginx.pid;
events {
 use epoll;
 worker_connections 2048;
}
http {
 include 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 logs/access.log main;
 sendfile on;
 # tcp_nopush on;
 keepalive_timeout 65;
 # gzip压缩功能设置
 gzip on;
 gzip_min_length 1k;
 gzip_buffers 4 16k;
 gzip_http_version 1.0;
 gzip_comp_level 6;
 gzip_types text/html text/plain text/css text/javascript application/json application/javascript application/x-javascript application/xml;
 gzip_vary on;
 
 # http_proxy 设置

 proxy_buffers 4 32k;
 proxy_busy_buffers_size k;
 proxy_temp_file_write_size k;
 proxy_temp_path /usr/local/nginx/proxy_temp 1 2;
