How to install the Tomcat 7 environment in CentOS

Install JDK

Download the JDK on the Oracle Java SEDownload page.

(1) Check "Accept License Agreement 」

(2) click jdk-8u91-linux-x64.rpm 」

If the system is 64-bit, select x64, and if the system is 32-bit, select i586.

(3) upload the downloaded file to the server over FTP.

(4) install JDK

# Rpm-ivh./jdk-8u91-linux-x64.rpm
Install Tomcat

In Apache Tomcat-Welcome! Download Tomcat from the Downloads page.

# Wget http://ftp.kddilabs.jp/infosystems/apache/tomcat/tomcat-7/v7.0.70/bin/apache-tomcat-7.0.70.tar.gz
# Tar zxvf./apache-tomcat-7.0.70.tar.gz-C/usr/local/

(2) add a tomcat user

# Useradd-m-d/home/tomcat
# Chown-R tomcat: Maid/usr/local/apache-tomcat-7.0.70/

(3) the apache-tomcat-7.0.7 directory is too long. Make a soft link to/usr/local/tomcat and modify the user

# Ln-s/usr/local/apache-tomcat-7.0.70/usr/local/tomcat
# Chown-h tomcat./usr/local/tomcat

(4) Start tomcat

# Sudo-u tomcat/usr/local/tomcat/bin/startup. sh

(5) enter http: // IP address: 8080/

Run the following command to stop Tomcat.

# Sudo-u tomcat/usr/local/tomcat/bin/shutdown. sh

Create a Tomcat startup/Stop script

(1) create the/etc/init. d/tomcat file.

The code is as follows:

Copy code

#! /Bin/bash # Chkconfig: 2345 10 90 # Description: tomcat service # Source function library. ./Etc/init. d/functions CATALINA_HOME = "/usr/local/tomcat" CATALINA_PID = "/usr/local/tomcat/catalina. pid" TOMCAT_USER = "tomcat" NAME = "tomcat" RETVAL =$? Case "$1" in Start) If [-f "/var/lock/subsys/$ {NAME}"]; then Echo "Tomcat is already running" Exit 1 Fi Echo "Starting Tomcat" Sudo-u $ {TOMCAT_USER }$ {CATALINA_HOME}/bin/catalina. sh start Touch/var/lock/subsys/tomcat ;; Stop) If [! -F "/var/lock/subsys/$ {NAME}"]; then Echo "Tomcat is already stopping" Exit 1 Fi Echo "Stopping Tomcat" Sudo-u $ {TOMCAT_USER }$ {CATALINA_HOME}/bin/catalina. sh stop-force Rm-f/var/lock/subsys/tomcat ;; Restart) $0 stop Sleep 10 $0 start ;; Status) If [-f "$ {CATALINA_PID}"]; then Read kpid <$ {CATALINA_PID} If [-d "/proc/$ {kpid}"]; then Echo "$ {NAME} (pid $ {kpid}) is running ..." Else Echo "$ {NAME} is not running, but PID file exists" Fi Else Echo "$ {NAME} is stopped" Fi ;; *) Echo "Usage: $0 {start | stop | restart | status }" Exit 1 ;; Esac Exit $ {RETVAL}

Startup. sh and shutdown. sh are not used here. You can use catalina. sh to start and stop tomcat directly.

(2) grant the execution permission to the script

# Chmod + x/etc/init. d/tomcat

(3) configure automatic start upon startup

# Chkconfig -- add tomcat
# Chkconfig -- list | grep tomcat
# Chkconfig tomcat on

Apache and Tomcat

Listen on port 80 of Apache and use Apache ProxyPass to enable Tomcat.

# Vi/etc/httpd/conf/httpd. conf
ProxyPass/tomcat/ajp: // localhost: 8009/
ProxyPass/examples/ajp: // localhost: 8009/examples/

Restart httpd to access Tomcat through port 80.
