SUCCESS!
4.tomcat安裝
4.1安裝Tomcat並且給第一個Tomcat創建測試網頁
[root@qy-lnmt ~]# yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel
[root@qy-lnmt ~]# java -version
openjdk version "1.8.0_201"
[root@qy-lnmt src]# ls
apache-tomcat-9.0.16.tar.gz kernels
[root@qy-lnmt src]# tar xf apache-tomcat-9.0.16.tar.gz -C /usr/local/
[root@qy-lnmt src]# cd /usr/local/
[root@qy-lnmt local]# ln -s apache-tomcat-9.0.16/ tomcat
[root@qy-lnmt ~]# vi index.jsp
[root@qy-lnmt ~]# cat index.jsp
<html>
<head>
<title>test page</title>
</head>
<body>
<%
out.println("xfssb");
%>
</body>
</html>
[root@qy-lnmt ~]# mkdir /usr/local/tomcat/webapps/test
[root@qy-lnmt ~]# cp index.jsp /usr/local/tomcat/webapps/test/
[root@qy-lnmt ~]# /usr/local/tomcat/bin/catalina.sh start
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@qy-lnmt ~]# ps -ef|grep tomcat

[root@qy-lnmt src]# cp -a apache-tomcat-9.0.16 /usr/local/apache-tomcat2
[root@qy-lnmt src]# ln -s /usr/local/apache-tomcat2/ /usr/local/tomcat/2
[root@qy-lnmt ~]# cd /usr/local/apache-tomcat2/conf/
[root@qy-lnmt conf]# pwd
/usr/local/apache-tomcat2/conf
[root@qy-lnmt conf]# vim server.xml
22行<Server port="8006" shutdown="SHUTDOWN"> 第一個端口
69行 <Connector port="8081" protocol="HTTP/1.1" 第二個端口

71 redirectPort="8443" />
115 <!-- Define an AJP 1.3 Connector on port 8010 --> 第三個端口
116 <Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />
先進入頁面驗證tomcat是否安裝成功
4.2給第二個Tomcat創建測試網頁
在/usr/local/apache-tomcat2/webapps/目錄下新建test目錄
[root@qy-lnmt ~]# cd /usr/local/apache-tomcat2/webapps/test/
[root@qy-lnmt test]# vim index.jsp
[root@qy-lnmt test]# cat index.jsp
<html>
<head>
<title>test page</title>
</head>
<body>
<%
out.println(" dmv ");
%>
</body>
[root@qy-lnmt webapps]# /usr/local/apache-tomcat2/bin/startup.sh
Using CATALINA_BASE: /usr/local/apache-tomcat2
Using CATALINA_HOME: /usr/local/apache-tomcat2
Using CATALINA_TMPDIR: /usr/local/apache-tomcat2/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/apache-tomcat2/bin/bootstrap.jar:/usr/local/apache-tomcat2/bin/tomcat-juli.jar
Tomcat started.
[root@qy-lnmt ~]# ss -antl

4.3 三臺服務整合，修改nginx配置文件，配置負載均衡和反向代理
[root@qy-lnmt ~]# vim /usr/local/nginx/conf/nginx.conf
27 sendfile on;
28 #tcp_nopush on;
29
30 #keepalive_timeout 0;
31 keepalive_timeout 65;
32
33 #gzip on;
34 upstream web.com { \\增加以下四行
35 server 192.168.69.134:8080;
36 server 192.168.69.134:8081;
37 }
38
39 server {
40 listen 80;
43 #charset koi8-r;
44
45 #access_log logs/host.access.log main;
46 增加以下三行
47 location ~* \.(jsp|do)$ {
48 proxy_pass http://web.com;
49 }
50 location / {
51 root html;
52 index index.html index.htm;
53 }
驗證負載均衡是否成功
重啓nginx
第一次
第二次網頁測試
