Sshpass

sshpass 命令

  • centos安装
$ yum install -y epel-release
$ yum install sshpass

如果没有该版本的rpm 包， 可以参考二进制安装

1、从https://sourceforge.net/projects/sshpass/files/sshpass/ 下载指定版本的 sshpass， 这里以1.10 版本为例子

$ tar -zxvf sshpass-1.05.tar.gz
$ cd sshpass-1.05

#指定安装目录
$ ./configure --prefix=/opt/sshpass
$ make
$ make install
$ cp /opt/sshpass/bin/sshpass /usr/bin/

2、sshpass -V 验证安装完成

$ /opt/sshpass/bin/sshpass -V
sshpass 1.10

例子，使用sshpass 反向代理端口

1、创建service文件（/etc/systemd/system/nacos-sshpass.service）

[Unit]
Description=Nacos Application  Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target


[Service]
Type=simple
ExecStart=/opt/sshpass/bin/sshpass -p 'abc123!' ssh -L 0.0.0.0:32659:localhost:32659 -C -q -N root@192.168.101.100
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s


[Install]
WantedBy=multi-user.target

实现功能为将 192.168.101.100上的32659端口，正向代理到本地使用localhost:32659 进行访问。

使用下述命令启动服务nacos-sshpass

$ chmod +x /etc/systemd/system/nacos-sshpass.service
$ systemctl enable --now nacos-sshpass.service
