centos中安装tomcat7,并实现web程序的热部署

• 安装前先检查jdk是否安装，如果没有安装，则先安装jdk

[root@tomcat home]# java -versionjava version "1.6.0_33"OpenJDK Runtime Environment (IcedTea6 1.13.5) (rhel-1.13.5.1.el6_6-x86_64)OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)

• 从官网中下载tar.gz,并解压到/usr/local/tomcat

[root@tomcat home]# wget http://mirrors.cnnic.cn/apache/tomcat/tomcat-7/v7.0.65/bin/apache-tomcat-7.0.65.tar.gz[root@tomcat home]# tar -zxvf apache-tomcat-7.0.65.tar.gz[root@tomcat home]# mv apache-tomcat-7.0.65 /usr/local/tomcat[root@tomcat home]# cd /usr/local/tomcat

• 修改tomcat的配置文件，增加host，实现web文件的热部署。

[root@tomcat tomcat]# vim conf/server.xml<Host name="192.168.0.222"  appBase="/data/tomcat/webapps_xxx"            unpackWARs="true" autoDeploy="true">                    </Host>

• 新建webapps_xxx的目录，用于存放maven编译的war包

[root@tomcat tomcat]# mkdir -p /data/tomcat/webapps_xxx

• 开放防火墙监听端口8080

[root@tomcat tomcat]/sbin/iptables -I INPUT -p tcp --dport 8080 -j ACCEPT   [root@tomcat tomcat]/etc/rc.d/init.d/iptables save  [root@tomcat tomcat]/etc/init.d/iptables restart  

启动tomcat

[root@tomcat tomcat]# ./bin/startup.sh

查看启动日志

[root@tomcat tomcat]# tail -f logs/catalina.out 

• 用maven打包一个xxx.war项目,然后放在/home目录下，复制到/data/tomcat/webapps_xxx下并重命名为ROOT.war

[root@tomcat tomcat]# mv xxx.war webapps_xxx/ROOT.war

如果此时在查看tomcat日志，则可以看到刚部署的xxx.war已经自动开始部署，无需重启tomcat

• 关于tomcat的一些技巧及基本配置
  1、配置tomcat开机启动
  在etc/rc.local中添加，tomcatstart.sh是新建的tomcat启动文件

[root@tomcat tomcat]# vim /etc/rc.local

在末尾增加：/usr/local/bin/tomcatstart.sh

#!/bin/sh## This script will be executed *after* all the other init scripts.# You can put your own initialization stuff in here if you don't# want to do the full Sys V style init stuff.touch /var/lock/subsys/local/usr/local/bin/tomcatstart.sh

在/usr/local/bin中新建一个tomcatstart.sh文件

[root@tomcat tomcat]# vim /usr/local/bin/tomcatstart.sh

内容如下：

#!/bin/bashexport TOMCAT_HOME='/usr/local/tomcat'$TOMCAT_HOME/bin/startup.sh

修改执行权限

[root@tomcat tomcat] cd /usr/local/bin[root@tomcat bin] chmod 775 tomcatstart.sh 

至此开机启动已完成

2、在centos中增加快捷访问路径

[root@tomcat tomcat] vim ~/.bashrc
导入export data=’/data/luqiao/tomcat’

# .bashrc# User specific aliases and functionsalias rm='rm -i'alias cp='cp -i'alias mv='mv -i'# Source global definitionsif [ -f /etc/bashrc ]; then        . /etc/bashrcfiexport tomcat='/usr/local/tomcat'

[root@tomcat tomcat] source ~/.bashrc

验证快捷路径是否生效：

[root@tomcat tomcat] cd /home[root@tomcat tomcat] cd $tomcat[root@tomcat tomcat] pwd/usr/local/tomcat

此时则证明成功添加快捷路径
