检查 nginx 是否已经配置了 SSH 模块

shell
nginx -V

打印如下

shell
$ nginx -V
nginx version: nginx/1.24.0
built by gcc 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1) 
built with OpenSSL 1.1.1f  31 Mar 2020
TLS SNI support enabled
configure arguments: --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.45

configure arguments 中 不存在 --with-stream, 说明不支持 SSH

找到 nginx 的 configure 的位置

shell
sudo find /usr -name "configure" | grep "nginx"

找到如下

shell
/usr/local/src/nginx-1.24.0/configure

使用 configure 安装 SSH 模块

安装

shell
sudo ./configure --with-stream
