ssh 连接 centos 服务器时报警告：
-bash: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such file or directory
原因是 ssh连接的时候会传递环境变量，这个变量如在服务器没有的环境，就会报这个错误，是LC_CTYPE这个环境变量导致的提示。
对于LC_CTYPE的参数，我们一般建议设置成UTF-8，服务器上配置文件缺少相应配置参数。所以就报错了。
解决办法：
在centos上运行
vi /etc/locale.conf
内容改为：
LANG=en_US.utf8
LC_ALL=en_US.utf8
LC_CTYPE=en_US.utf8
重新连接ssh，就可以解决错误提示。
proxmox 升到7，或是安装7后的版本在使用旧的pct模版LXC的 Centos 7 无法开机，出现以下错误提示：
WARN: old systemd (< v232) detected, container won't run in a pure cgroupv2 environment! Please see documentation -> container -> cgroup version.
TASK WARNINGS: 1
解決方法如下
vim /etc/default/grub
找到以下
GRUB_CMDLINE_LINUX_DEFAULT=”quiet”
改成以下
GRUB_CMDLINE_LINUX_DEFAULT=”systemd.unified_cgroup_hierarchy=0 quiet”
运行更新grub
update-grub
重启服务器
reboot
2020年11月30日 centos6各大开源镜像站已经停止维护了！但是阿里源还是可以用的通道，因为他的centos-vault仓库里放了之前版本的centos的包。
只需要在centos命令行界面下执行一下几条命令即可解决问题。命令如下：
1 2 3 4 5 | sed -i "s|enabled=1|enabled=0|g" /etc/yum/pluginconf.d/fastestmirror.conf mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup curl -o /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Aliyun.repo yum clean all yum makecache |
如无法下载Centos-6-Vault-Aliyun.repo文件，可以将以下内容复制存为文件使用即可。
