在tomcat-users.xml中配置賬號(hào)密碼后，記得重啟tomcat，修改的東西才有效

為什么設(shè)置好了用戶名和密碼之后可以進(jìn)入后臺(tái),但再次重啟tomcat用戶名就登錄不上了?失效了!!! ? ? ? ? ? ? ? ?tomcat-users.xml里面也沒有了剛剛的配置!

.o0.0o. ?哈哈 謝謝

O(∩_∩)O非常感謝！~

直接在tomcat-user.xml文件中的<tomcat-users></tomcat-users>之間加入上面這一句即可，這句話的意思是吧用戶名設(shè)置為tomcat，密碼設(shè)為123。

不要把<!-- -->這個(gè)符號(hào)去掉，這里是注釋，舉例說明你可以把名字密碼設(shè)置為各種類型。

我只加了一個(gè)角色manager-gui就可以訪問了，role="admin-gui"是什么意思，也是系統(tǒng)里內(nèi)置的么？@諾顏寧

非常感謝,已成功.

打開Tomcate安裝文件中的conf文件夾，之后打開tomcat-users.xml文件，在<tomcat-users></tomcat-users>的標(biāo)簽之間j加入一下代碼，此時(shí)你的用戶名和密碼是admin，這樣就可以實(shí)現(xiàn)你想要的了
