记一次GitLab-CE跨版本从11升级到13踩的坑

环境

OS:CentOS 8
Hostname:HyperV-GitLab

---

1.不可跨大版本升级

必须先升级到当前大版本的最新版 在升级到下一个大版本
参考官方网站对于版本升级的说明

2.pg_dump: aborting because of server version mismatch

因为使用了外部数据源（PG），而且是12的高版本，GitLab自带pg_dump版本只到10或者11。在升级的备份部分，就备份失败，报错如下：

gitlab preinstall: Automatically backing up only the GitLab SQL database (excluding everything else!)
2020-10-01 21:47:39 +0800 -- Dumping database ... 
Dumping PostgreSQL database db_gitlab ... pg_dump: server version: 12.4; pg_dump version: 11.7
pg_dump: aborting because of server version mismatch
[FAILED]
rake aborted!
Backup::Error: Backup failed

解决方法：

1.安装postgresql12的客户端
dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
dnf -qy module disable postgresql
dnf install -y postgresql12

2.重新建立pg_dump的软连接
cd /opt/gitlab/embedded/bin
mv pg_dump pg_dump.bak
ln -s /usr/bin/pg_dump /opt/gitlab/embedded/bin/pg_dump

3.error: %prein(gitlab-ce-13.1.11-ce.0.el8.x86_64) scriptlet failed, exit status 1

GitLab一开始就用Yum/dnf安装，后面升级自然也一直用Yum命令升级；只到从13.1.4升级到13.1.11版本时，一直提示

[root@HyperV-GitLab opt]# yum update gitlab-ce-13.1.11

用rpm -Uvvh查看安装详情，发现错误如下：

可能是因为我安装系统的时候选择了中文，系统里竟然没有英文语言包？！
locale -a如下：

[root@HyperV-GitLab ~]# vi /etc/environment
[root@HyperV-GitLab ~]# locale -a
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory

zh_CN.utf8
zh_HK
zh_HK.utf8
zh_SG

解决方法：
安装英文语言包

yum install langpacks-en.noarch
