Tomcat 部署：
准备部署tomcat前的一些准备工作：
groupadd tomcat -g1002
useradd tomcat-u 1002 -g 1002
passwd tomcat
tomcat123!@#
[root@rabbitmq_slave tomcat_software]#pwd
/usr/local/src/tomcat_software
[root@rabbitmq_slavetomcat_software]# ll
total 96416
-rw-r--r-- 1 rootroot 8234674 May 16 08:59apache-tomcat-7.0.47.tar.gz
-rw-r--r-- 1 rootroot 1016391 May 16 09:08apr-1.5.0.tar.gz
-rw-r--r-- 1 rootroot 874462 May 16 09:08apr-util-1.5.3.tar.gz
-rw-r--r-- 1 rootroot 2934099 May 16 09:00 apr.zip
-rw-r--r-- 1 rootroot 85414670 May 16 09:08 jdk-7u25-linux-x64.rpm
-rw-r--r-- 1 rootroot 241274 May 16 09:14tomcat-native-1.1.20-src.tar.gz
在安装Tomcat之前需要安装j2sdk(Java 2Software Development Kit)，也就是JDK。
接下来开始安装JDK并设置环境变量：
[root@rabbitmq_slave tomcat_software]# rpm -ivh jdk-7u25-linux-x64.rpm
[root@rabbitmq_slave tomcat_software]# ln -s /usr/java/jdk1.7.0_25 /usr/local/jdk
vi /etc/profile #在他文件末尾处添加下面的变量：
# java
JAVA_HOME=/usr/local/jdk
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME
export PATH
export CLASSPATH
[root@rabbitmq_slave tomcat_software]# source/etc/profile
查看jdk是否安装成功，执行以下命令：
[root@rabbitmq_slave~]# java -version
java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixedmode)
如果控制台输出jdk的版本类似如上1.7.0_25，则表明安装成功。
安装tomcat
[root@rabbitmq_slave tomcat_software]# pwd
/usr/local/src/tomcat_software
[root@rabbitmq_slave tomcat_software]# tar zxfapache-tomcat-7.0.47.tar.gz -C /usr/
[root@rabbitmq_slave tomcat_software]# cd /usr/
[root@rabbitmq_slave usr]# mv apache-tomcat-7.0.47 /usr/local/tomcat7
[root@rabbitmq_slave usr]# cd /usr/local/tomcat7/conf
[root@rabbitmq_slave conf]# pwd
/usr/local/tomcat7/conf
[root@rabbitmq_slave conf]# cat tomcat-users.xml

[root@rabbitmq_slave conf]# cd /usr/local/tomcat7/bin/
chowntomcat:tomcat /usr/local/tomcat7/ -R
[root@rabbitmq_slavebin]# su – tomcat
[tomcat@rabbitmq_slave~]$ cd /usr/local/tomcat7/bin
使用tomcat用户启动tomcat后台执行：
[tomcat@rabbitmq_slave bin]$ nohup &
启动后，网页测试，在浏览器中输入http://ip:8080。看能否显示tomcat界面,用admin用户登录试试。
