# unicorn出错
|
|
|
|
## 问题描述
|
|
|
|
通过`docker`部署`gitlab`一段时间后，突然出现`502`错误
|
|
|
|
查看容器状态，显示不健康
|
|
|
|
```
|
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
|
89481faa2ed1 gitlab/gitlab-ce:latest "/assets/wrapper" 2 weeks ago Up 7 hours (unhealthy)
|
|
```
|
|
|
|
浏览容器日志，发现如下错误：
|
|
|
|
```
|
|
==> /var/log/gitlab/unicorn/unicorn_stdout.log <==
|
|
bundler: failed to load command: unicorn (/opt/gitlab/embedded/bin/unicorn)

## 问题解析
|
|
|
|
看样子是`unicorn`的问题，参考：

|
|
|
|
进入容器内部，查看`unicorn`状态
|
|
|
|
```
|
|
$ docker exec -it xxxx bash
|
|
# gitlab-ctl tail unicorn
|
|
```
|
|
|
|
发现每次`unicorn`显示的`PID`都不同，修改`/etc/gitlab/gitlab.rb`，添加
|
|
|
|
```
|
|
unicorn['listen'] = 'localhost'
|
|
unicorn['port'] = 8999
|
|
```
|
|
|
|
更新并重启后，`gitlab`服务恢复正常
|
|
|
|
```
|
|
# gitlab-ctl reconfigure
|
|
# gitlab-ctl restart
|
|
``` |
