centos做个登录提醒

1.编辑脚本

sudo vim /usr/local/bin/login-notify.sh

例如 login-notify.sh

#!/bin/bash


# 检查是否有一个原始SSH命令，并执行它
if [[ -n "$SSH_ORIGINAL_COMMAND" ]]; then
    echo "SSH_ORIGINAL_COMMAND: $SSH_ORIGINAL_COMMAND" >> /var/log/ssh-login-notify.log

    #exec $SSH_ORIGINAL_COMMAND BUG 有空格不会执行
    eval $SSH_ORIGINAL_COMMAND
else
    # 记录登录信息
    MESSAGE="localnews服务器:用户 $(whoami) 从 ${SSH_CLIENT%% *} 登录于
$(date)"
    echo $MESSAGE >> /var/log/ssh-login-notify.log
    # 执行用户的原始 shell
    exec $SHELL
fi

• sudo chmod +x /usr/local/bin/login-notify.sh

2.配置sshd

sudo vim /etc/ssh/sshd_config

新增

ForceCommand /usr/local/bin/ssh-login-notify.sh

重启

sudo systemctl restart sshd
