要访问机器上除了80以外的端口需要域名加上端口链接，这样很不方便，所以就想用nginx把需要的服务代理到80端口。 nginx的配置文件在/etc/nginx/下，新增的网站服务的配置可以直接写下conf.d或者sites-enabled下面。具体可以查看nginx的nginx.conf配置文件中关于Virtual Host Configs的设置 一个比较好的安排配置文件的方法是：在sites-available中保存所有的配置，然后复制需要的配置到sited-enabled启用配置。 假设新建一个newserver配置文件 server { listen 80; server_name {domainname}.com; location / { proxy_pass http://127.0.0.1:8081;#add the port your service are listening proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } 软链接到sites-enabled cd /etc/nginx cp sites-available/newserver sites-enabled/ ……

在尝试了几个windows的终端后，还是觉得windows terminal最好用。 windows terminal 链接 https://github.com/microsoft/terminal defaultProfile填写配置对应的guid就可以设置默认配置。所有的配置在profiles中。 安装好git之后，windows可以使用bash了。 { "acrylicOpacity" : 0.9, "closeOnExit" : true, "colorScheme" : "Solarized Light", "commandline" : "C:\\Program Files\\Git\\bin\\bash.exe", "cursorColor" : "#1100fc", "cursorShape" : "bar", "fontFace" : "Consolas", "fontSize" : 12, "guid" : "{61c54bbd-c2c6-5271-96e7-009a87ff44bf}", "historySize" : 9001, "icon" : "C:\\Program Files\\Git\\mingw64\\share\\git\\git-for-windows.ico", "name" : "bash", "padding" : "0, 0, 0, 0", "snapOnInput" : true, "startingDirectory" : "%USERPROFILE%", "useAcrylic" : true } ……

expect可以帮助我们 自动化完成一些交互操作。 使用expect来执行ssh命令 编写脚本 #!/usr/bin/expect #sshlogin.exp set timeout 30 set host "192.168.1.8" set username "your_username" set password "yout_password" spawn ssh [email protected]$host #expect "*password:*" {send "$password\r"} expect { "*password:" {send "$password\r"} } interact 给脚本权限 chmod 755 运行脚本 ./sshlogin.exp 使用一行命令直接运行 expect -c 'spawn ssh {{username}}@{{host}}; expect "*password:*"; send "{{password}}\r"; interact' references: https://en.wikipedia.org/wiki/Expect https://stackoverflow.com/questions/3149367/how-to-get-expect-c-to-work-in-single-line-rather-than-script……
