网站维护

查找tomcat的containerID,进入tomacat目录：

[root@promote ~]# docker ps CONTAINER ID  IMAGE    COMMAND     CREATED    STATUS    PORTS     NAMESb52c4a46a432  nginx    "/docker-entrypoin..." 4 minutes ago  Up 4 minutes  0.0.0.0:8081->80/tcp  nginx-test02ffbf387631  tomcat    "catalina.sh run"  45 minutes ago  Up 45 minutes  0.0.0.0:8080->8080/tcp mytomcat

查看webapps发现里面为空

[root@promote ~]# docker exec -it 02ffbf387631 /bin/bashroot@02ffbf387631:/usr/local/tomcat# ls -ltotal 124-rw-r--r--. 1 root root 18982 Sep 10 08:25 BUILDING.txt-rw-r--r--. 1 root root 5409 Sep 10 08:25 CONTRIBUTING.md-rw-r--r--. 1 root root 57092 Sep 10 08:25 LICENSE-rw-r--r--. 1 root root 2333 Sep 10 08:25 NOTICE-rw-r--r--. 1 root root 3257 Sep 10 08:25 README.md-rw-r--r--. 1 root root 6898 Sep 10 08:25 RELEASE-NOTES-rw-r--r--. 1 root root 16262 Sep 10 08:25 RUNNING.txtdrwxr-xr-x. 2 root root 4096 Sep 15 22:33 bindrwxr-xr-x. 1 root root 22 Oct 10 01:45 confdrwxr-xr-x. 2 root root 4096 Sep 15 22:33 libdrwxrwxrwx. 1 root root 177 Oct 10 01:45 logsdrwxr-xr-x. 2 root root 134 Sep 15 22:33 native-jni-libdrwxrwxrwx. 2 root root 30 Sep 15 22:33 tempdrwxr-xr-x. 2 root root  6 Sep 15 22:33 webappsdrwxr-xr-x. 7 root root 81 Sep 10 08:23 webapps.distdrwxrwxrwx. 2 root root  6 Sep 10 08:20 workroot@02ffbf387631:/usr/local/tomcat# cd webappsroot@02ffbf387631:/usr/local/tomcat/webapps# ls -ltotal 0

删除webapps,将webapps.dist修改名称为webapps

root@02ffbf387631:/usr/local/tomcat/webapps# cd ..root@02ffbf387631:/usr/local/tomcat# rm -rf webappsroot@02ffbf387631:/usr/local/tomcat# mv webapps.dist webappsroot@02ffbf387631:/usr/local/tomcat# cd webappsroot@02ffbf387631:/usr/local/tomcat/webapps# ls -ltotal 8drwxr-xr-x. 3 root root 4096 Sep 15 22:33 ROOTdrwxr-xr-x. 15 root root 4096 Sep 15 22:33 docsdrwxr-xr-x. 6 root root 83 Sep 15 22:33 examplesdrwxr-xr-x. 5 root root 87 Sep 15 22:33 host-managerdrwxr-xr-x. 6 root root 114 Sep 15 22:33 manager

重新在浏览器中访问：

没有提交的话，在镜像重启后，又会报404错误，要commit一下

[root@promote ~]# docker psCONTAINER ID  IMAGE    COMMAND     CREATED    STATUS    PORTS     NAMESb52c4a46a432  nginx    "/docker-entrypoin..." 43 minutes ago  Up 42 minutes  0.0.0.0:8081->80/tcp  nginx-test02ffbf387631  tomcat    "catalina.sh run"  About an hour ago Up About an hour 0.0.0.0:8080->8080/tcp mytomcat[root@promote ~]# docker commit 02ffbf387631 mytomcatsha256:b2c4b37c92c5c26b1285756bf04365b8f5a42a86d519a767ea528cda1af9a81a

再次访问就不需要配置，直接访问tomcat页面了
