CentOS配置Tomcat以服务方式启动

在CentOS系统中安装Tomcat7并设置为自启动服务。

1、 软件

a)        下载apache-tomcat-7.0.27 地址： http://apache.etoak.com/tomcat/tomcat-7/v7.0.27/bin/apache-tomcat-7.0.27.tar.gz

b)        如无特殊说明，本文档操作用户为tomcat

2、 安装

a)        解压

1 # tar zxvf apache-tomcat-7.0.27.zip

b)        移动到其他目录

# mv apache-tomcat-7.0.27 /home/tomcat/tomcat

c)        启动Tomcat服务

# cd /home/tomcat/tomcat/bin

# ./startup.sh

d)        检查是否启动成功

在本机浏览器中访问URL: http://localhost:8080/

会出现Tomcat的欢迎页面

注：如果想远程通过浏览器访问，则在远程浏览器中输入http://<ip>:8080/

<ip> 可通过在本地机器上输入命令 ifconfig 查看

如果未能访问到tomcat的欢迎页面，需要查看本机的防火墙设置，是否打开了端口8080

e)        停止服务

# ./shutdown.sh

3、 可能出现的问题

a)        Java未先安装，或未正确配置JAVA_HOME系统环境变量

b)        Linux系统的防火墙8080端口未被设置为远程可访问

4、配置tomcat由tomcat用户自启动（使用jsvc）

a)        编译安装jsvc

# export CATALINA_HOME=/home/tomcat/tomcat

# cd $CATALINA_HOME/bin

# tar xvfz commons-daemon-native.tar.gz

# cd commons-daemon-1.0.8-native-src/unix

# ./configure

# make

# cp jsvc ../..

b)        编写自启动脚本：用root用户登录，创建脚本tomcat7

# vi /etc/init.d/tomcat7

添加如下脚本：

#! /bin/sh

 

# chkconfig: 35 96 04

# description: Apache-Tomcat service script.

#        2008-01-17-01

        srch_rst=$(ps -A|grep $APP_PROC|awk '{print $4}')

                echo "Usage: $0 {start|stop|restart}"

                exit 1

        ;;

esac

exit 0

注意修改APP_HOME为tomcat实际安装路径，APP_USER为启动tomcat的用户。

c)        设置tomcat自启动服务

使用如下命令给tomcat7增加执行权限

# chmod +x tomcat7

将tomcat添加到启动服务中

# chkconfig --add tomcat7

# chkconfig --level 234 tomcat7 on

可以用如下命令确认是否配置成功

# chkconfig --list tomcat7

之后就可以用service来控制tomcat的启动和停止了。

# service tomcat7 start

# service tomcat7 stop

查看/home/tomcat/tomcat/logs/catalina-daemon.out，确认没有error
