CentOS运维一句话药到病除

yum update更新的时候,内存不足溢出完蛋了,安装包出现很多duplicate之类的。

rpm -e --nodeps `package-cleanup --dupes|awk '{ a=1-a; if(!a) print $0 }'`

There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them.

yum-complete-transaction --cleanup-only

怎么查看磁盘使用情况?

df -h

用了centmin之后磁盘空间不够了怎么办?

ccache -C
du -sh /svr-setup
cd /svr-setup/
rm -rf /svr-setup/*
cd /usr/local/nginxbackup
rm -rf /usr/local/nginxbackup/nginxdirbackup/*
rm -rf /usr/local/nginxbackup/confbackup/*

不记得nginx的路径了

which nginx

ps aux | grep nginx
