Linux下安裝Nginx

1. 下載nginx：http://nginx.org/en/download.html

2. 安裝依賴包

   yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel
   
   // 安裝過(guò)程中，要選擇：y
   yum install GeoIP gd libXpm libxslt
   
   // 安裝gcc gcc-c++
   yum -y install gcc gcc-c++ autoconf automake make
   

3. 安裝nginx

   // 解壓
   tar -zxvf nginx-1.14.0.tar.gz
   
   cd nginx-1.14.0/
   
   // 安裝到/usr/local/nginx目錄下
   ./configure --prefix=/usr/local/nginx
   
   make
   
   make install
   

nginx常用命令

• 啟動(dòng)命令：/usr/local/nginx/sbin/nginx
• 重啟命令：/usr/local/nginx/sbin/nginx -s reload
• 查看命令：ps -ef | grep nginx
• 關(guān)閉命令：kill -9 進(jìn)程號(hào)

nginx常用配置

配置文件位置：/usr/local/nginx/conf/nginx.conf

Nginx初試Tomcat不脯，部署Guns-admin

網(wǎng)上關(guān)于nginx的資料很零碎府怯，我就想整個(gè)tomcat+nginx運(yùn)行一下guns的項(xiàng)目而已，訪問(wèn)admin.idudiao.com后轉(zhuǎn)到服務(wù)器上的 http://localhost:8080/guns-admin上防楷，無(wú)果牺丙，不是重定向次數(shù)過(guò)多，就是session失效复局。
最后赘被，用了個(gè)折中的法子是整，訪問(wèn)admin.idudiao.com后轉(zhuǎn)到服務(wù)器上的 http://localhost:8080

1. 部署guns-admin項(xiàng)目，同時(shí)修改項(xiàng)目發(fā)布路徑為：''民假。 修改tomcat/conf/server.xml

   <Host name="localhost"  appBase="webapps"
           unpackWARs="true" autoDeploy="true">
   
       <!-- SingleSignOn valve, share authentication between web applications
            Documentation at: /docs/config/valve.html -->
       <!--
       <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
       -->
       
       <!--修改發(fā)布路徑-->
       <Context path="" docBase="/tomcat-8.0.53-guns/webapps/guns-admin"  debug="0" reloadable="true"/>
   
       <!-- Access log processes all example.
            Documentation at: /docs/config/valve.html
            Note: The pattern used is equivalent to using pattern="common" -->
       <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
              prefix="localhost_access_log" suffix=".txt"
              pattern="%h %l %u %t &quot;%r&quot; %s %b" />
   
     </Host>
   
   

   參考：https://blog.csdn.net/u011042133/article/details/46349593

   • path是虛擬路徑；
   • docBase是應(yīng)用程序的物理路徑龙优；
   • debug則是設(shè)定debug level, 0表示提供最少的信息羊异，9表示提供最多的信息；
   • reloadable 如果為true彤断，則tomcat會(huì)自動(dòng)檢測(cè)應(yīng)用程序的/WEB-INF/lib 和/WEB-INF/classes目錄的變化野舶，自動(dòng)裝載新的應(yīng)用程序，可以在不重起

2. 配置Nginx宰衙，修改/usr/local/nginx/conf/nginx.conf文件平道，在http{}模塊下添加：

   http {
       ...
       
       #add by dudiao at 20180815
       server {
           listen 80;
           server_name admin.idudiao.com;
           
           location / {
               proxy_pass http://localhost:8080;
               proxy_set_header Host $host;
               proxy_set_header X-Real-IP $remote_addr;
               proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           }
   
           location ~ .*\.(gif|jpg|jpeg|png|js|css)$ {
               root /tomcat-8.0.53-guns/webapps/guns-admin/;
               expires 1d;
           }
       }
       #add by dudiao end
       
       ...
   }
