How To Install ProxySQL:

Ubuntu and Debian:

Configuring APT repository

apt-get update && apt-get install -y --no-install-recommends lsb-release wget apt-transport-https ca-certificates
wget -nv -O /usr/share/keyrings/proxysql-3.0.x-keyring.gpg 'https://repo.proxysql.com/ProxySQL/proxysql-3.0.x/repo_pub_key.gpg'
echo "deb [signed-by=/usr/share/keyrings/proxysql-3.0.x-keyring.gpg] https://repo.proxysql.com/ProxySQL/proxysql-3.0.x/$(lsb_release -sc)/ ./" | tee /etc/apt/sources.list.d/proxysql.list
Note: the signed-by keyring method above works on Debian 9+ and Ubuntu 16.04+. The older apt-key add method is deprecated and has been removed in Debian 12 and Ubuntu 24.04. Note: on older EOL distros, due to expired ca-certificates, you may need to use http:// instead of https:// or manualy update ca-certificates
