Linux环境下安装Nginx及其使用

飞奔的炮台

这篇文章主要介绍了Linux环境下安装Nginx及其使用，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
一、查看centos的版本

cat /etc/redhat-release

二、添加资源库
在 centos 系统上安装 nginx ，得先去添加一个资源库：

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

三、安装nginx

yum -y install nginx

四、测试nginx配置文件是否正确

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
  client_max_body_size  10m;
  client_body_buffer_size  128k;
  proxy_connect_timeout  75;
  proxy_send_timeout  75;
  proxy_read_timeout  75;
  proxy_buffer_size  4k;
  proxy_buffers  4 32k;
  proxy_busy_buffers_size  64k;
  proxy_temp_file_write_size 64k;
  proxy_temp_path  /usr/local/nginx/proxy_temp 1 2;
 # 设定负载均衡后台服务器列表 
  upstream backend { 
     #ip_hash; 
     server  192.168.10.100:8080 max_fails=2 fail_timeout=30s ; 
     server  192.168.10.101:8080 max_fails=2 fail_timeout=30s ; 
  }
 # 很重要的虚拟主机配置
  server {
  listen  80;
  server_name itoatest.example.com;
  root  /apps/oaapp;
  charset utf-8;
  access_log logs/host.access.log main;
  #对 / 所有做负载均衡+反向代理
  location / {
    root  /apps/oaapp;
    index index.jsp index.html index.htm;
    proxy_pass  http://backend; 
    proxy_redirect off;
    # 后端的web服务器可以通过x-forwarded-for获取用户真实ip
    proxy_set_header host $host;
    proxy_set_header x-real-ip $remote_addr; 
    proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
    proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
    
  }
  #静态文件，nginx自己处理，不去backend请求tomcat
  location ~* /download/ { 
    root /apps/oa/fs; 
    
  }
  location ~ .*\.(gif|jpg|jpeg|bmp|png|ico|txt|js|css)$  
  {  
    root /apps/oaapp;  
    expires   7d; 
  }
  location /nginx_status {
    stub_status on;
    access_log off;
    allow 192.168.10.0/24;
    deny all;
  }
  location ~ ^/(web-inf)/ {  
    deny all;  
  }
  #error_page 404     /404.html;
  # redirect server error pages to the static page /50x.html
  #
  error_page  500 502 503 504 /50x.html;
  location = /50x.html {
    root  html;
  }
  }
 ## 其它虚拟主机，server 指令开始
}
