Install mo_ctl

Depending on whether you have Internet access, you can choose to install the mo_ctl tool online or offline. You need to be careful to always execute commands as root or with sudo privileges (and add sudo before each command). Meanwhile, install.sh will use the unzip command to extract the mo_ctl package. Make sure the unzip command is installed.

Install online

wget https://raw.githubusercontent.com/matrixorigin/mo_ctl_standalone/main/install.sh && sudo bash +x ./install.sh

# Alternate address
wget https://ghproxy.com/https://github.com/matrixorigin/mo_ctl_standalone/blob/main/install.sh && sudo bash +x install.sh

For users running this command in a macOS environment, if you are a non-root user, run install.sh with the following statement:

sudo -u $(whoami) bash +x ./install.sh

Offline installation

# 1. Download the installation script to your local computer before uploading it to the installation machine
