Linux 下面安装tomcat
一：停止tomcat服务，一般tomcat安装都是通过安装包的形式安装，因此，只需要将tomcat的安装文件删除掉即可。
1：找到tomcat的安装路径，停止服务
[root@li1062-188 /]# cd /usr/local [root@li1062-188 local]# ls -l total 56 drwxr-xr-x 9 root root 4096 Apr 29 03:14 apache-tomcat-7.0.69 drwxr-xr-x 2 root root 4096 Sep 23 2011 bin drwxr-xr-x 2 root root 4096 Sep 23 2011 etc drwxr-xr-x 2 root root 4096 Sep 23 2011 games drwxr-xr-x 2 root root 4096 Sep 23 2011 include drwxr-xr-x 2 root root 4096 Sep 23 2011 lib drwxr-xr-x 2 root root 4096 Sep 23 2011 lib64 drwxrwxrwx 8 501 games 4096 Apr 11 03:55 libevent-1.4.12-stable drwxr-xr-x 2 root root 4096 Sep 23 2011 libexec drwxr-xr-x 5 root root 4096 Apr 8 09:08 memcached drwxrwxr-x 7 1000 1000 4096 Apr 8 09:08 memcached-1.4.25 drwxr-xr-x 2 root root 4096 Sep 23 2011 sbin drwxr-xr-x 5 root root 4096 Mar 9 2014 share drwxr-xr-x 2 root root 4096 Sep 23 2011 src [root@li1062-188 local]# cd apache-tomcat-7.0.69/ [root@li1062-188 apache-tomcat-7.0.69]# ls -l total 116 drwxr-xr-x 2 root root 4096 Apr 29 03:31 bin drwxr-xr-x 3 root root 4096 Apr 29 06:53 conf drwxr-xr-x 2 root root 4096 Apr 29 03:14 lib -rw-r--r-- 1 root root 56846 Apr 11 07:59 LICENSE drwxr-xr-x 2 root root 4096 Apr 29 06:53 logs -rw-r--r-- 1 root root 1239 Apr 11 07:59 NOTICE -rw-r--r-- 1 root root 8965 Apr 11 07:59 RELEASE-NOTES -rw-r--r-- 1 root root 16195 Apr 11 07:59 RUNNING.txt drwxr-xr-x 2 root root 4096 Apr 29 03:14 temp drwxr-xr-x 7 root root 4096 Apr 11 07:58 webapps drwxr-xr-x 3 root root 4096 Apr 29 06:53 work [root@li1062-188 apache-tomcat-7.0.69]# cd bin [root@li1062-188 bin]# ./shutdown.sh Using CATALINA_BASE: /usr/local/apache-tomcat-7.0.69 Using CATALINA_HOME: /usr/local/apache-tomcat-7.0.69 Using CATALINA_TMPDIR: /usr/local/apache-tomcat-7.0.69/temp Using JRE_HOME: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.101.x86_64 Using CLASSPATH: /usr/local/apache-tomcat-7.0.69/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.69/bin/tomcat-juli.jar [root@li1062-188 bin]#
2：删除tomcat文件。
[root@li1062-188 local]# rm -rf apache-tomcat-7.0.69/ [root@li1062-188 local]#
3：查找对应的配置文件，在/etc/profile下面，如果有，就注释或者删除，然后，使之立即生效
[root@li1062-188 local]# echo $CATALINA_HOME [root@li1062-188 local]# source /etc/profile [root@li1062-188 local]#
二：下载对应的tomat包，并配置环境，我们想要下载tomcat7.0
1：下载tomcat7.0
[root@li1062-188 local]# yum -y list tomcat* Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.linode.com * extras: mirrors.linode.com * updates: mirrors.linode.com Available Packages tomcat6.x86_64 6.0.24-94.el6_7 updates tomcat6-admin-webapps.x86_64 6.0.24-94.el6_7 updates tomcat6-docs-webapp.x86_64 6.0.24-94.el6_7 updates tomcat6-el-2.1-api.x86_64 6.0.24-94.el6_7 updates tomcat6-javadoc.x86_64 6.0.24-94.el6_7 updates tomcat6-jsp-2.1-api.x86_64 6.0.24-94.el6_7 updates tomcat6-lib.x86_64 6.0.24-94.el6_7 updates tomcat6-servlet-2.5-api.x86_64 6.0.24-94.el6_7 updates tomcat6-webapps.x86_64 6.0.24-94.el6_7 updates tomcatjss.noarch

下载完成之后，解压到/usr/local路径下面。
2：配置环境变量
[root@li1062-188 bin]# vi catalina.sh #!/bin/sh CATALINA_HOME=/usr/local/apache-tomcat-7.0.69/
3：启动，停止，查看日志 服务
[root@li1062-188 bin]# ./shutdown.sh

4：启动mysql后，访问 http://ip:8080/ 看看有没有出现界面。
