This article mainly explains the "install tomcat under centos7 and use systemd to achieve tomcat multi-instance configuration method", the content of the article is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "install tomcat under centos7 and use systemd to achieve tomcat multi-instance configuration method"!

In this article, we share the method of installing tomcat in Centos, and then using systemd to achieve multiple instances of tomcat, which can be carefully referenced by friends who need it.

System environment: CentOS 7 x86x64

1. Install jdk

Rpm-ivh jdk-8u60-linux-x64.rpm

2. Create ordinary users

Getent group tomcat | | groupadd-r tomcat

Getent passwd tomcat | | useradd-r-d / opt-s / bin/nologin tomcat

3. Download tomcat 7

Cd / opt

Wget http://mirrors.ustc.edu.cn/apache/tomcat/tomcat-7/v7.0.64/bin/apache-tomcat-7.0.64.tar.gz

Tar zxvf apache-tomcat-7.0.64.tar.gz

Mv apache-tomcat-7.0.64 tomcat01

Chown-R tomcat:tomcat tomcat01

Tar zxvf apache-tomcat-7.0.64.tar.gz

Mv apache-tomcat-7.0.64 tomcat02

Chown-R tomcat:tomcat tomcat02

Two instances listening to port 8080 at the same time will inevitably lead to conflict, so it must be modified.

Sed-I's Universe 8080max 8081Compact g'/ opt/tomcat01/conf/server.xml

Sed-I's Universe 8005 / opt/tomcat01/conf/server.xml 8001gamma

Sed-I's Universe 8080max 8082Compact g'/ opt/tomcat02/conf/server.xml

Sed-I's Universe 8005 / opt/tomcat02/conf/server.xml 8005 / 8002

AJP is usually not used, it is closed here.

The default working mode of tomcat under Linux is bio, and the performance is very low. It is recommended to use apr or nio.

This is changed to nio, that is, non-blocking IO, and the performance is better.

Sed-i.bak 's copyright HTTP hand 1.1 milliorg.apache.coyote.http11.Http11NioProtocoloration'/ opt/tomcat01/conf/server.xml

Sed-i.bak 's copyright HTTP hand 1.1 milliorg.apache.coyote.http11.Http11NioProtocoloration'/ opt/tomcat02/conf/server.xml

4. Create a startup file

Cd / usr/lib/systemd/system

Cat > tomcat01.service
