启动完 tomcat 点下图框中默认会报错,因为没有账号密码,尝试多次后会报 401
我们需要修改 conf/tomcat-users.xml 文件即可,下载在登录时输入 username 当时配置的即可正常登录
[root@localhost tomcat]# cat conf/tomcat-users.xml
<?xml version="1.0" encoding="UTF-8"?>
<tomcat-users xmlns="http://tomcat.apache.org/xml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
version="1.0">
<role rolename="admin-gui"/>
<role rolename="host-gui"/>
<role rolename="manager-gui"/>
<user username="admin" password="admin" roles="admin-gui,host-gui,manager-gui"/>
</tomcat-users>
#配置完成后需要重启
在执行./shutdown后一定要查看进程和端口在不在

tomcat8.5 以后的版本默认只允许机访问,换需要修改 webapps/manager/META-INF/context.xml
#将value class的行注释掉即可
[root@localhost tomcat]# cat webapps/manager/META-INF/context.xml
<?xml version="1.0" encoding="UTF-8"?>
<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" />
-->
<Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>
