CentOS在登录时候显示cannot change locale (zh_CN.UTF-8): No such file or directory的解决办法 1.centos登录时报错-bash: warning: setlocale: LC_CTYPE: cannot change locale (zh_CN.UTF-8): No such file or directory -bash: warning: setlocale: LC_COLLATE: cannot change locale (zh_CN.UTF-8): No such file or directory -bash: warning: setlocale: LC_MESSAGES: cannot change locale (zh_CN.UTF-8): No such file or directory -bash: warning: setlocale: LC_NUMERIC: cannot change locale (zh_CN.UTF-8): No such file or directory -bash: warning: setlocale: LC_TIME: cannot change locale (zh_CN.UTF-8): No such file or directory2.修改locale中文字符集时重新加载环境变量报错解决方法：vi /etc/profile export LC_ALL=C

shell 获取当前脚本的绝对路径 1.单脚本这个是有缺陷的，⽐比如脚本A source 了另一个⽬目录下的脚本B, 然后脚本B尝试使⽤用此法获取路路径时得到的是A的路路径current_path=$(cd "$(dirname $0)";pwd)或current_path=$( cd $(dirname $0) pwd )2.脚本中引用脚本(推荐)current_path=$(cd $(dirname "${BASH_SOURCE[0]}") && pwd)或current_path=$( cd $(dirname "${BASH_SOURCE[0]}") pwd )

宝塔面板取消强制登录验证7.6.0版本后 宝塔面板7.6.0版本后增强了强制用户绑定账号只需要在SSH中输入：1.方法一：sed -i "s|if (bind_user == 'True') {|if (bind_user == 'REMOVED') {|g" /www/server/panel/BTPanel/static/js/index.js恢复登录：sed -i "s|if (bind_user == 'REMOVED') {|if (bind_user == 'True') {|g" /www/server/panel/BTPanel/static/js/index.js2.方法二：适用7.6.0版本rm -f /www/server/panel/data/bind.pl3.合并命令：sed -i "s|if (bind_user == 'True') {|if (bind_user == 'REMOVED') {|g" /www/server/panel/BTPanel/static/js/index.js && rm -f /www/server/panel/data/bind.pl2021-12-29发现验证又改了修改198行，去掉notvi /www/server/panel/BTPanel/__init__.py
