安装Nginx 1.26.2

wget https://nginx.org/download/nginx-1.26.2.tar.gz
tar -zxvf nginx-1.26.2.tar.gz
cd nginx-1.26.2/
安装PCRE包，如果不不安装，configure需要加入参数 --without-http_rewrite_module
sudo apt-get install libpcre3 libpcre3-dev
这里参数只是加了SSL插件。如果还需要其他插件，继续添加其他参数
./configure --with-http_ssl_module
make
sudo make install
