生產(chǎn)勿用
vim /application/tomcat/conf/tomcat-users.xml
##在</tomcat-users>行上添加三行
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="tomcat" password="tomcat123" roles="manager-gui, admin-gui"/>
如果想要進(jìn)入/manager/html頁(yè)面缎除，則新建或編輯conf/Catalina/localhost/manager.xml
如果想要進(jìn)入/host-manager/html頁(yè)面严就，則新建或編輯conf/Catalina/localhost/host-manager.xml
配置文件如下
<?xml version="1.0" encoding="UTF-8"?>

[root@sanqi webapps]# mv docs/ examples/ host-manager/ manager/ /tmp
[root@sanqi webapps]# rm -rf ROOT/*

這里有點(diǎn)小坑,配完后,訪問一直報(bào)400
找了好久
后來發(fā)現(xiàn)竟然是因?yàn)閡pstream名稱不能用'_'
我去啊,那我重啟你倒是報(bào)錯(cuò)啊
