CentOS系統下安裝Tomcat7環境教程

安裝JDK

在Oracle Java SEDownload頁面下載JDK。

(1) 勾選「Accept License Agreement」

(2) 點擊「jdk-8u91-linux-x64.rpm」

系統為64位時選擇x64，32位時選擇i586。

(3) 把下載的檔案用FTP上傳到伺服器。

(4) 安裝JDK

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

在Apache Tomcat – Welcome!的Downloads頁面下載Tomcat。

# 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) 添加tomcat使用者

# useradd -m -d /home/tomcat tomcat
# chown -R tomcat:tomcat /usr/local/apache-tomcat-7.0.70/

(3) apache-tomcat-7.0.7目錄太長，做個軟連結到/usr/local/tomcat,並修改使用者

# ln -s /usr/local/apache-tomcat-7.0.70 /usr/local/tomcat
# chown -h tomcat. /usr/local/tomcat

(4) 啟動tomcat

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

(5) 輸入http://IP地址:8080/

停止Tomcat時，執行如下命令。

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

建立Tomcat啟動/停止指令碼

(1) 建立/etc/init.d/tomcat檔案。

代碼如下

複製代碼

#!/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}

在這裡不實用startup.sh和shutdown.sh，直接用catalina.sh進行tomcat啟動及停止。

(2) 指令碼賦予執行許可權

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

(3) 配置開機自動啟動

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

Apache和Tomcat

在Apache的80連接埠監聽，然後用Apache ProxyPass啟用Tomcat。

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

之後重啟httpd就可以用80連接埠訪問Tomcat。
