Install OpenLiteSpeed

Access OpenLiteSpeed ​​Web Admin

After installing OpenLiteSpeed, you can access OpenLiteSpeed ​​Web Admin: https://ip:port. When accessing the admin website for the first time you will encounter the security warning Your connection is not private NET::ERR_CERT_AUTHORITY_INVALID. This warning is not serious, because by default the OpenLiteSpeed ​​web admin uses a self-signed certificate on the server.

You can choose one of two ways: continue accessing or install an SSL certificate for the web admin

Method 1: Continue accessing on Chrome

Method 1: Continue accessing on Safari

Click Visit Website

Method 2: Install SSL certificate for web admin

   # change 101082 to the id corresponding to the website's SSL ID
   sed -i 's/admin\/conf\/webadmin/conf\/cert\/101082\/server/' /usr/local/lsws/admin/conf/admin_config.conf
   sudo /usr/local/lsws/bin/lshttpd -t
   sudo systemctl restart lsws

4. Access web admin using domain:port (default 7080)

LiteSpeed ​​Cache
