CentOS下安装Tomcat7

1.检查java版本信息

#java -version
java version "1.7.0_65"
OpenJDK Runtime Environment (rhel-2.5.1.2.el6_5-x86_64 u65-b17)
OpenJDK -Bit Server VM (build 24.65-b04, mixed mode)

如果没有则安装，则安装jdk

1.1、(以下方式强烈不建议，因为有时候会缺少jar包，导致tomcat启动不成功)：

yum -y install java-1.7.-openjdk

1.2、强烈建议安装oracle的jdk包，此处安装jdk7,到如下网站下载：http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk7-downloads-1880260.html

下载：jdk-7u79-linux-x64.tar.gz到/tmp
解压：tar xzf jdk-7u79-linux-x64.tar.gz
移动：mv jdk1..0_79 /usr/local/java

添加环境变量 vim /etc/profile  ,在文件末尾添加：

export JAVA_HOME=/usr/local/java
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

立马生效：source /etc/profile

2. 下载并解压缩tomcat

# cd /tmp
# wget http://apache.fayea.com/tomcat/tomcat-7/v7.0.72/bin/apache-tomcat-7.0.72.tar.gz

# tar xzf apache-tomcat-7.0.72.tar.gz
# mv apache-tomcat-7.0.72 /usr/local/tomcat7

3. 启动tomcat

# cd /usr/local/tomcat7
# ./bin/startup.sh
如果以上命令不行，则进入bin文件夹运行 sh startup.sh

[输出样例]

Using CATALINA_BASE:   /usr/local/tomcat7
Using CATALINA_HOME:   /usr/local/tomcat7
Using CATALINA_TMPDIR: /usr/local/tomcat7/temp
Using JRE_HOME:        /usr/local/java
Using CLASSPATH:       /usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar
Tomcat started.

4. 访问http://ip:8080

5. 设置用户账户（可暂时忽略）

<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user username="tomcat" password="tomcat" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/>

6. 重启tomcat服务,进入/usr/local/tomcat7目录

 # ./bin/shutdown.sh
 # ./bin/startup.sh

如果以上命令不行，则进入bin文件夹运行 sh shutdown.sh 或者 sh startup.sh
