• 安裝前先檢查jdk是否安裝，如果沒有安裝，則先安裝jdk

[root@tomcat home]# java -version
java 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)

• 從官網中下載tar.gz,並解壓到/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的配置檔案，增加host，實現web檔案的熱部署。

[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的目錄，用於存放maven編譯的war包

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

• 開放防火牆監聽埠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  
 

啟動tomcat

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

檢視啟動日誌

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

• 用maven打包一個xxx.war專案,然後放在/home目錄下，複製到/data/tomcat/webapps_xxx下並重命名為ROOT.war

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

如果此時在檢視tomcat日誌，則可以看到剛部署的xxx.war已經自動開始部署，無需重啟tomcat

• 關於tomcat的一些技巧及基本配置
  1、配置tomcat開機啟動
  在etc/rc.local中新增，tomcatstart.sh是新建的tomcat啟動檔案

[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中新建一個tomcatstart.sh檔案

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

內容如下：

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

修改執行許可權

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

至此開機啟動已完成

2、在centos中增加快捷訪問路徑

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

# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi
export tomcat='/usr/local/tomcat'

[root@tomcat tomcat] source ~/.bashrc

驗證快捷路徑是否生效：

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

此時則證明成功新增快捷路徑
