首先下载压缩包
wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.78/bin/apache-tomcat-7.0.78.zip
如果centos7是最小版安装的话，还需要安装配置java环境
可参考http://www.cnblogs.com/biaopei/p/7730484.html
解压
unzip apache-tomcat-7.0.78.zip
[root@bogon src]# ls
apache-tomcat-7.0.78 kernels linux-3.10.1.tar.gz upload
apache-tomcat-7.0.78.zip linux-2.6.1 linux-3.4.16 utility
debug linux-3.10.1 readme
[root@bogon src]# cd apache-tomcat-7.0.78/
[root@bogon apache-tomcat-7.0.78]# ls
bin lib logs RELEASE-NOTES temp work
conf LICENSE NOTICE RUNNING.txt webapps
[root@bogon apache-tomcat-7.0.78]# cd bin
[root@bogon bin]# ls
bootstrap.jar daemon.sh startup.sh
catalina.bat digest.bat tomcat-juli.jar
catalina.sh digest.sh tomcat-native.tar.gz
catalina-tasks.xml setclasspath.bat tool-wrapper.bat
commons-daemon.jar setclasspath.sh tool-wrapper.sh
commons-daemon-native.tar.gz shutdown.bat version.bat
configtest.bat shutdown.sh version.sh
configtest.sh startup.bat
[root@bogon bin]#
需要给该目录下的三个文件执行权限chmod 755
这三个文件你分别是catalina.sh shutdown.sh startup.sh
开启tomcat需要执行./startup.sh
关闭tomcat需要执行./shudown.sh
浏览器打开localhost:8080进行访问
啥，不能访问，喜欢简单粗暴的就直接关闭防火墙，绅士一点就让防火墙通过8080端口吧,即执行以下命令
iptables -I INPUT -p tcp –dport=8080 -j ACCEPT
给个成功效果图 
不出意外的话，tomcat虽然可以正常访问，但是，我们无法进入图形化管理后台，这个还需要另外配置
[root@localhost ~]# cd apache-tomcat-9.0.2/conf/
[root@localhost conf]# ls
Catalina catalina.policy catalina.properties context.xml jaspic-providers.xml jaspic-providers.xsd logging.properties server.xml tomcat-users.xml tomcat-users.xsd web.xml
配置tomcat-users.xml文件，在该文件末尾增加以下内容
<role rolename=”manager-gui”/>
<user username=”tomcat” password=”123456″ roles=”manager-gui”/>
除此之外还需要配置
[root@localhost META-INF]# pwd
/root/apache-tomcat-9.0.2/webapps/manager/META-INF
[root@localhost META-INF]# ls
context.xml
[root@localhost META-INF]# cat context.xml
<?xml version=”1.0″ encoding=”UTF-8″?>

最后重启，就可以进入tomcat的server status了，用户名为tomcat，密码123456
tomcat网站目录位于apache-tomcat-9.0.2/webapps/ROOT目录下
