1. Install tomcat

Official website to download

https://tomcat.apache.org/

Download tomcat 8
Select Distributions- Binary> Core-> tar.gz
the Apache-Tomcat-8.5.53.tar.gz

After the download is good

root$ cp apache-tomcat-8.5.53.tar.gz /opt/
root$ cd /opt
root$ tar xf apache-tomcat-8.5.53.tar.gz
root$ rm apache-tomcat-8.5.53.tar.gz
root$ cd apache-tomcat-8.5.53/bin
root$ ./catalina.sh run

After running a successful start to see the following information Description

23-Mar-2020 17:27:43.021 信息 [main] org.apache.catalina.startup.Catalina.start

Server startup in 3181 ms

2.tomcat application deployment

root$ cd /opt/apache-tomcat-8.5.53/webapps/
root$ cp docs/appdev/sample/sample.war ./
root$ cd ../bin/
root$ ./shutdown.sh
root$ ./catalina.sh run

// server ip address:: We can go to http: 8080 visit, the remote can be http: // localhost 8080

If the remote access error, it may be a firewall, the firewall access to port 8080 open

firewall-cmd --zone=public --add-port=8080/tcp --permanent
systemctl restart firewalld

3. Install Nginx

yum install nginx -y

Before starting nginx, apache must ensure that the service is turned off, otherwise nginx will fail to start, because apache and nginx default port 80

systemctl stop httpd
systemctl start ngnix

We can at http: // localhost access

Nginx configuration to achieve reverse proxy and load balancing

4. The same project started two tomcat

Then copy tomcat, and modify the port number, etc., to boot

cd /opt
cp -r apache-tomcat-8.5.53 apache-tomcat-8.5.53-copy2

Modify apache-tomcat-8.5.53-copy2 / conf / server.xml, modify the port number three

The Foreign port to 8081, and to ensure the external port apache-tomcat-8.5.53 does not conflict,

<Connector port="8081" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />

The 8005 change 8006

<Server port="8006" shutdown="SHUTDOWN">
<Listener className="org.apache.catalina.startup.VersionLoggerListener" />


<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />

<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
<Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />

The 8009 change 8010
