今天好好的服务突然打不开了，以为是postresql问题，到服务器上瞧瞧，结果发现本地无法登陆psql控制台，怪了，之前好好的没动过服务器啊。
平时正常运行的命令莫名奇妙报错：
su - postgres psql
/usr/bin/psql: line 19: use: command not found
/usr/bin/psql: line 20: use: command not found
/usr/bin/psql: line 21: use: command not found
/usr/bin/psql: psql: line 23: syntax error near unexpected token `$version,'
/usr/bin/psql: psql: line 23: `my ($version, $cluster, $db, $port, $host);'
sudo -u postgres psql
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
ls /va 按Tab快速补齐时报错：
odoo-bash: cannot create temp file for here-document: No space left on device
-bash: cannot create temp file for here-document: No space left on device
经查是 /dev/vda1 磁盘空间满了
df -h

先去占用空间最大的135G的 odoo 目录中去看看有没有要清理的文件
cd /odoo
sudo du -sh *

原来是我的备份长时间没清理，到今天终于把硬盘空间耗完了，找到原因，那么就清理一下吧。
sudo rm -rf backups/*
