Linux环境下安装Nginx及其使用

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.servicesystemctl restart nginx.servicesystemctl 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}
