0、安装JDK
1、下载tomcat8.5
官网：Apache Tomcat® - Apache Tomcat 8 Software Downloads
下载地址：https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.54/bin/apache-tomcat-8.5.54.tar.gz
centos 下载命令：curl -O https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.54/bin/apache-tomcat-8.5.54.tar.gz
解压：tar -zxvf apache-tomcat-8.5.54.tar.gz
2、配置xml
进入conf文件夹配置tomcat-users.xml:
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<user username="admin" password="123456" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-gui,admin-script"/>
配置host-manager远程访问：
在apache-tomcat-8.5.24/webapps/host-manager/META-INF/文件夹下找到content.xml:
修改
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127.d .d .d |::1|0:0:0:0:0:0:0:1" />
为：
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="d .d .d .d |::1|0:0:0:0:0:0:0:1" />
tomcat目录/conf/Catalina/localhost/下 添加manager.xml
<Context privileged="true" antiResourceLocking="false"
docBase="${catalina.home}/webapps/manager">
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^.*$" />
</Context>
如果不执行这步. 则只能localhost访问manager!!!
配置完成，适用于8.5
