harbor1.7.1的访问报错502 bad gateway
背景：
在访问harbor镜像仓库时提示报错如下：
问题分析：
根据提供的报错内容来看时harbor服务的nginx组件服务异常了的，导致无法访问harbor服务，查看harbor服务结果如下：
service@harbor:~/harbor$ docker-compose ps

redis docker-entrypoint.sh redis ... Up 6379/tcp
registry /entrypoint.sh /etc/regist ... Up 5000/tcp
registryctl /harbor/start.sh Up 根据docker-compose ps查询的内容来看，是harbor-portal组件服务异常了，导致了nginx组件服务也异常了。
这时候查看harbor服务各个组件的健康状态情况，通过docker ps服务查看
service@harbor:~/harbor$ docker ps -a

这里可以发现nginx处于unhealthy,不健康的状态。
这时候需要分析harbor-portal组件服务为什么报错了，因为harbor使用了syslog服务作为存放日志，所以我们只需要到/var/log/harbor目录下找到对应的服务日志文件查看即可。
service@harbor:/var/log/harbor$ tail -1000f portal.log
........
Jun 4 03:58:54 localhost portal[119121]: 2024/06/03 19:58:54 [emerg] 1#0: mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied)
Jun 4 03:58:54 localhost portal[119121]: nginx: [emerg] mkdir() "/etc//nginx/client_body_temp" failed (13: Permission denied)
根据日志的提示是portal容器在运行的时候需要创建/etc/nginx/client_body_temp目录，但是提示权限不足无法创建。
问题解决方案：
这里的处理方案就是重新创建portal服务即可。
先停止harbor-portal服务
service@harbor:~/harbor$ docker-compose stop portal
Stopping harbor-portal ... done
查看是否已经停止掉harbor-portal服务
service@harbor:~/harbor$ docker-compose ps

这时候发现nginx服务也是healthy状态了，然后去浏览器上访问一下：
然后去输入账号密码即可。
