| 主機 | 操作系統 | IP地址 | 所需軟件 |
|---|---|---|---|
| Nginx Server | CentOS7 | 192.168.109.7 | nginx-1.12.0.tar.gz |
| Tomcat Server1 | CentOS7 | 192.168.109.22 | apache-tomcat-9.0.16.tar.gz、jdk-8u201-linux-x64.rpm |
| Tomcat Server2 | CentOS7 | 192.168.109.23 | apache-tomcat-9.0.16.tar.gz、jdk-8u201-linux-x64.rpm |
#!/bin/bash #腳本說明：編譯安裝nginx服務 #注意：使用前請將nginx-1.12.0.tar.gz放入/opt目錄下 #關閉防火墻 systemctl stop firewalld systemctl disable firewalld setenforce 0 #安裝所需開發包和編譯環境、編譯器 yum -y install pcre-devel zlib-devel openssl-devel gcc gcc-c++ make #創建程序用戶，便于準確控制訪問 useradd -M -s /sbin/nologin nginx #解壓安裝包 cd /opt tar zxvf nginx-1.12.0.tar.gz -C /opt/ #編譯安裝nginx；指定安裝路徑、指定用戶名、組名、啟用模塊以支持統計狀態 cd /opt/nginx-1.12.0/ ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-file-aio --with-http_gzip_static_module --with-http_flv_module --with-http_ssl_module make && make install #軟鏈接便于系統識別nginx操作命令 ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/ #添加nginx系統服務 echo '[Unit] Description=nginx After=network.target [Service] Type=forking PIDFile=/usr/local/nginx/logs/nginx.pid ExecStart=/usr/local/nginx/sbin/nginx ExecrReload=/bin/kill -s HUP $MAINPID ExecrStop=/bin/kill -s QUIT $MAINPID PrivateTmp=true [Install] WantedBy=multi-user.target' > /lib/systemd/system/nginx.service #賦權及開啟服務、開啟開機自啟 chmod 754 /lib/systemd/system/nginx.service systemctl restart nginx.service systemctl enable nginx.service
2、部署兩臺 Tomcat 應用服務器
#!/bin/bash #安裝Tomcat服務 #關閉防火墻 systemctl stop firewalld systemctl disable firewalld setenforce 0 #安裝JDK cd /opt rpm -ivh jdk-8u201-linux-x64.rpm #設置JDK環境變量 echo 'export JAVA_HOME=/usr/java/jdk1.8.0_201-amd64 export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar export PATH=$JAVA_HOME/bin:$PATH' > /etc/profile.d/java.sh source /etc/profile #安裝并啟動Tomcat cd /opt tar zxvf apache-tomcat-9.0.16.tar.gz mv apache-tomcat-9.0.16 /usr/local/tomcat /usr/local/tomcat/bin/startup.sh
3、動靜分離配置
請看tomcat
1）Tomcat1 server 配置
mkdir /usr/local/tomcat/webapps/test
#配置動態頁面
vim /usr/local/tomcat/webapps/test/index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<title>JSP test1 page</title>
</head>
<body>
<% out.println("動態頁面 1:www.test1.com");%>
</body>
</html>
#修改配置文件 vim /usr/local/tomcat/conf/server.xml <Host name="192" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> <Context docBase="/usr/local/tomcat/webapps/test" path="" reloadable="true" /> </Host> /usr/local/tomcat/bin/shutdown.sh /usr/local/tomcat/bin/startup.sh
2）Tomcat2 server 配置
mkdir /usr/local/tomcat/webapps/test
vim /usr/local/tomcat/webapps/test/index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<title>JSP test2 page</title>
</head>
<body>
<% out.println("動態頁面 1:www.test2.com");%>
</body>
</html>
#修改配置文件 vim /usr/local/tomcat/conf/server.xml <Host name="192" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> <Context docBase="/usr/local/tomcat/webapps/test" path="" reloadable="true" /> </Host> /usr/local/tomcat/bin/shutdown.sh /usr/local/tomcat/bin/startup.sh
3）Nginx server 配置
#準備靜態頁面和靜態圖片 echo '<html><body><h1>this is static</h1></body></html>' > /usr/local/nginx/html/index.html mkdir /usr/local/nginx/html/long cd /usr/local/nginx/html/long
vim /usr/local/nginx/conf/nginx.conf
......
http {
......
#gzip on;
upstream tomcat_server {
server 192.168.109.22:8080 weight=1;
server 192.168.109.23:8080 weight=1;
}
server {
listen 80;
server_name www.long.com;
#charset koi8-r;
#access_log logs/host.access.log main;
#配置Nginx處理動態頁面請求，將 .jsp 文件請求轉發到Tomcat 服務器處理
location ~ .*\.jsp$ {
proxy_pass http://tomcat_server;
proxy_set_header HOST $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
#配置Nginx處理靜態圖片請求
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|css)$ {
root /usr/local/nginx/html/img/;
expires 10d;
}
location / {
root html;
index index.html index.htm;
}
systemctl restart nginx.service
4、訪問測試
測試靜態頁面效果
瀏覽器訪問 http://192.168.109.7/
瀏覽器訪問 http://192.168.109.7/long.jpg
測試負載均衡效果，不斷刷新瀏覽器測試
瀏覽器訪問 http://192.168.109.7/test/index.jsp
到此這篇關于Nginx+Tomcat實現負載均衡、動靜分離的原理解析的文章就介紹到這了,更多相關Nginx負載均衡、動靜分離內容請搜索腳本之家以前的文章或繼續瀏覽下面的相關文章希望大家以后多多支持腳本之家！
