一、背景：
在巡检rancher平台时发现有一个服务运行报错了，查看该服务容器事件时提示连接不到harbor镜像仓库。
二、harbor镜像仓库访问问题分析过程：
1、确认harbor仓库是否可以访问：
发现无法访问时，第一时间是通过浏览器去访问harbor仓库是否能正常访问：
http://harbor.jx.shu.com
发现无法访问，然后登入到对应的harbor服务器上去查看harbor服务是否正常。
2、查看分析harbor服务器的网络情况：
通过堡垒机去访问harbor服务器时发现无法登入上去，这时候就需要找硬件基础工程师进行处理了。
3、查看harbor服务运行状态：
硬件工程师处理好harbor服务器无法登入的问题，之后登入到harbor服务器上去，并通过docker-compose命令查看服务运行状态，如下：
root@harbor:/home/service/harbor# docker-compose ps Name Command State Ports ----------------------------------------------------------------------------------------------------------------------------------- harbor-adminserver /harbor/start.sh Up harbor-core /harbor/start.sh Up harbor-db /entrypoint.sh postgres Up 5432/tcp harbor-jobservice /harbor/start.sh Up harbor-log /bin/sh -c /usr/local/bin/ ... Up 127.0.0.1:1514->10514/tcp harbor-portal nginx -g daemon off; Restarting nginx nginx -g daemon off; Up 0.0.0.0:443->443/tcp, 0.0.0.0:4443->4443/tcp, 0.0.0.0:80->80/tcp redis docker-entrypoint.sh redis ... Up 6379/tcp registry /entrypoint.sh /etc/regist ... Up 5000/tcp registryctl /harbor/start.sh Up根据查询到情况，可以发现harbor-portal容器服务运行异常，然后查看harbor对应的yaml文件内容：

root@harbor:/home/service/harbor# cd /var/log/harbor/ root@harbor:/var/log/harbor# ls adminserver.log dev-198-1b9b616909af44f90ae1566674c19032ec13c8da.log portal.log proxy.log registryctl.log core.log jobservice.log postgresql.log redis.log registry.logroot@harbor:/var/log/harbor# tail -100f portal.log
查看的日志报错如下：
........ Feb 18 14:43:15 localhost portal[97624]: 2024/02/18 06:43:15 [emerg] 1#0: mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied) Feb 18 14:43:15 localhost portal[97624]: nginx: [emerg] mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied) Feb 18 14:43:41 localhost portal[97624]: 2024/02/18 06:43:41 [emerg] 1#0: mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied) Feb 18 14:43:41 localhost portal[97624]: nginx: [emerg] mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied) Feb 18 14:44:32 172.18.0.1 portal[97624]: 2024/02/18 06:44:32 [emerg] 1#0: mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied) Feb 18 14:44:32 172.18.0.1 portal[97624]: nginx: [emerg] mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied) Feb 18 14:46:15 172.18.0.1 portal[97624]: 2024/02/18 06:46:15 [emerg] 1#0: mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied) Feb 18 14:46:15 172.18.0.1 portal[97624]: nginx: [emerg] mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied) Feb 18 14:49:40 localhost portal[97624]: 2024/02/18 06:49:40 [emerg] 1#0: mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied) Feb 18 14:49:40 localhost portal[97624]: nginx: [emerg] mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied)但是该服务运行的不是nginx服务的，所以日志中报错的内容，提供不了排查方向。
4、解决harbor服务运行异常问题：
首先想到harbor服务器有重启过，是否有可能因为docker的网络有问题导致的，需要重启一下docker服务，然后再去重启一下harbor服务的。

Up 6379/tcp registry /entrypoint.sh /etc/regist ... Up 5000/tcp registryctl /harbor/start.sh Up然后发现还是不行，网络查找可以尝试通过install.sh脚本的访问处理，就尝试了一下：
root@harbor:/home/service/harbor# ./install.sh [Step 0]: checking installation environment ... Note: docker version: 17.03.2 Note: docker-compose version: 1.18.0 [Step 1]: preparing environment ...

For more details, please visit https://github.com/goharbor/harbor .再次查看harbor服务状态：
root@harbor:/home/service/harbor# docker-compose ps Name Command State Ports ------------------------------------------------------------------------------------------------------------------------------ harbor-adminserver /harbor/start.sh Up harbor-core /harbor/start.sh Up harbor-db /entrypoint.sh postgres Up 5432/tcp harbor-jobservice /harbor/start.sh Up harbor-log /bin/sh -c /usr/local/bin/ ...

Up 6379/tcp registry /entrypoint.sh /etc/regist ... Up 5000/tcp registryctl /harbor/start.sh Up发现harbor服务恢复了，通过访问地址去访问是可以正常打开，并且正常获取到镜像文件的。文章来源：https://www.toymoban.com/news/detail-827324.html
