Deploy multiple Tomcat servers on Linux
1. Upload the downloaded tomcat installation package to linux
Use the decompression command to decompress the file to the specified directory: tar -zxvf apache-tomcat-9.0.13.tar.gz -C /usr/local/
2. Modify multiple tomcat instance names
3. Modify the /etc/profile file and add two tomcat path configurations at the end of the file
`CATALINA_BASE=/usr/local/tomcat8080/apache-tomcat-9.0.65
CATALINA_HOME=/usr/local/tomcat8080/apache-tomcat-9.0.65
TOMCAT_HOME=/usr/local/tomcat8080/apache-tomcat-9.0.65
export CATALINA_BASE CATALINA_HOME TOMCAT_HOME
CATALINA2_BASE=/usr/local/tomcat8081
CATALINA2_HOME=/usr/local/tomcat8081
TOMCAT2_HOME=/usr/local/tomcat8081
export CATALINA_One_BASE CATALINA_One_HOME TOMCAT_One_HOME`
After modifying the file, enter the command: source /etc/profile to refresh the configuration, otherwise it will not take effect
4. Enter the bin directory of the second Tomcat to modify the catalina.sh file.
The first Tomcat needs no changes
The second Tomcat replaces CATALINA_BASE and CATALINA_HOME in catalina.sh in batches with the information corresponding to the second tomcat configured in /etc/profile
Switch directory: cd /usr/local/tomcat8081/bin
Modify the file: vim catalina.sh
Batch replacement:
%s/CATALINA_BASE/CATALINA2_BASE/g
%s/CATALINA_HOME/CATALINA2_HOME/g
5. Modify the port number in server.xml under the conf directory of tomcat:
Note: The first one doesn't need to modify anything except your own needs
Modify the information of the second tomcat:
change the closed port 8005 to 8006 and
the service port 8080 to 8081
6. At this point, the configuration has been completed. In the /bin directory of each tomcat, we start the two tomcats in turn, enter Command: ps -ef |grep tomcat View process
Two tomcats can also be accessed successfully in the browser
