ps -A列出所有进程，grep redis过滤出含有redis的行；

查出PID为1024的进程情况；

查出端口为80的进程情况；

退出PID为1024的进程，kill -9 1024为强制停止1024的进程；

ps -A | grep redis
lsof -p 1024
lsof -i :80
kill 1024

StandardOutput=append:__RUNPATH__/__NAME__.log
StandardError=append:__RUNPATH__/__NAME__.log
ExecReload=/bin/kill -s HUP $MAINPID
Restart=on-failure
User=root

[Install]
WantedBy=multi-user.target

配置 SSH 远程密钥登录，开放端口22，用户为root

1. 生成 RSA 密钥对，默认保存在/root/.ssh/id_rsa

ssh-keygen -t rsa -b 4096

2. 将生成的公钥内容写入授权列表

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
chmod 700 ~/.ssh/

3. 编辑 SSH 守护进程的配置文件/etc/ssh/sshd_config

Port 22
PermitRootLogin prohibit-password
PubkeyAuthentication yes
PasswordAuthentication no

4. 重启 SSH 服务应用更改

systemctl daemon-reload
systemctl restart sshd
systemctl restart ssh.socket
systemctl restart ssh
