CentOS6.5安装配置Tomcat方法

在进行安装配置Tomcat前请确保系统中已安装jdk并配置好java的环境变量，tomcat与jdk版本对应表如下所示

Servlet Spec	JSP Spec	EL Spec	WebSocket Spec	JASPIC Spec	Apache Tomcat Version	Latest Released Version	Supported Java Versions
4.0	TBD (2.4?)	TBD (3.1?)	TBD (1.2?)	1.1	9.0.x	9.0.0.M21 (alpha)	8 and later
3.1	2.3	3.0	1.1	1.1	8.5.x	8.5.15	7 and later
3.1	2.3	3.0	1.1	N/A	8.0.x (superseded)	8.0.44 (superseded)	7 and later
3.0	2.2	2.2	1.1	N/A	7.0.x	7.0.78	6 and later(7 and later for WebSocket)
2.5	2.1	2.1	N/A	N/A	6.0.x	6.0.53	5 and later
2.4	2.0	N/A	N/A	N/A	5.5.x (archived)	5.5.36 (archived)	1.4 and later
2.3	1.2	N/A	N/A	N/A	4.1.x (archived)	4.1.40 (archived)	1.3 and later
2.2	1.1	N/A	N/A	N/A	3.3.x (archived)	3.3.2 (archived)	1.1 and later

下面以安装配置tomcat 8.5.15为例。

1.到tomcat官网下载tomcat 8.5.15.tar.gz.

#wget –O apache-tomcat-8.5.15.tar.gz  http://mirrors.hust.edu.cn/apache/tomcat/tomcat-8/v8.5.15/bin/apache-tomcat-8.5.15.tar.gz

2.将下载好的压缩文件解压到当前文件夹，并复制到/usr/local/,且重命名为tomcat8

#tar zxvf apache-tomcat-8.5.15.tar.gz
#cp –R apache-tomcat-8.5.15 /usr/local/tomcat8

3.切换目录至/usr/local/tomvat8/bin，启动tomcat服务器

#cd /usr/local/tomcat8/bin
#./startup.sh

启动成功后，可以访问http://你的IP:8080,若访问成功，出现如下tomcat管理页面则表示安装成功，否则为安装失败。

4.因为此时tomcat并没有设置角色以及用户名密码等信息，所以点击manager apps等按钮时会出现403错误，此时需配置tomcat-users.xml添加角色及用户名密码，在tomcat-users.xml中<tomcat-users>*</tomcat-users>标签中间添加如下内容

<role rolename="tomcat"/>
<role rolename="manager-gui"/>
<user username="admin" password="123456" roles="tomcat,manager-gui"/>

5.配置好tomcat-users.xml文件后，重新启动服务器，若点击manager apps等按钮仍出现403错误，则需要对/usr/local/tomcat8/webapps/manager/META-INF/context.
a460
xml进行修改，注释掉其中的value标签。

<Context antiResourceLocking="false" privileged="true" >
<!--
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" >
-->
</Context>

再次重新启动tomcat，此时发现manager apps等功能已可以正常使用
