tomcat依赖jdk软件包，所以先配置jdk.
配置完成后 将下载好的tomcat 解压至/usr/local
tar -xvf apache-tomcat-7.0.70.tar.gz -C /usr/local
配置环境变量
编辑 vim /etc/profile.d/tomcat.sh
添加两行：
export CATALINA_HOME=/usr/local/apache-tomcat-7.0.70 export PATH=$PATH:$CATALINA_HOME/bin
让系统读一下配置文件
source /etc/profile.d/tomcat.sh
之后测试一下是否安装成功：
catalina.sh version
启动命令为：
catalina.sh start
启动后 可以使用
jps
命令来查看

要注意的是 /etc/hosts文件中，127.0.0.1 这一行 有没有问题 ，否则 导致启动失败，例如日志中下面的报错
最后 导致 进程关闭
