| 主機(jī) | 操作系統(tǒng) | 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 |

2、部署兩臺(tái) Tomcat 應(yīng)用服務(wù)器
#!/bin/bash #安裝Tomcat服務(wù) #關(guān)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(shè)置JDK環(huán)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(dòng)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(dòng)靜分離配置
請(qǐng)看tomcat
1）Tomcat1 server 配置
mkdir /usr/local/tomcat/webapps/test
#配置動(dòng)態(tài)頁(yè)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(dòng)態(tài)頁(yè)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(dòng)態(tài)頁(yè)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(zhǔn)備靜態(tài)頁(yè)面和靜態(tài)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(dòng)態(tài)頁(yè)面請(qǐng)求，將 .jsp 文件請(qǐng)求轉(zhuǎn)發(fā)到Tomcat 服務(wù)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 $proxy_add_x_forwarded_for;
}
#配置Nginx處理靜態(tài)圖片請(qǐng)求
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|css)$ {
root /usr/local/nginx/html/img/;
expires 10d;
}
location / {
root html;
index index.html index.htm;
}
systemctl restart nginx.service
4、訪問(wèn)測(cè)試
測(cè)試靜態(tài)頁(yè)面效果
瀏覽器訪問(wèn) http://192.168.109.7/
瀏覽器訪問(wèn) http://192.168.109.7/long.jpg
測(cè)試負(fù)載均衡效果，不斷刷新瀏覽器測(cè)試
