WARNING

If the MD5 code is inconsistent with the installation package's MD5 code displayed on the official website, although the installation is successful, there is the possibility that the installation file is tampered with!

# Installation Fail

Execute topio -v in any directory to verify whether the installation was successful.

If the following is output, the installation is failed.

-bash: topio: command not found

If the installation fails, please redo the installation steps.

# Download database (recommended)

For new servers, it is recommended that you download the database after installing TOPIO, which can reduce the time of data synchronization and start getting rewards early.

For advanced miners, the database must be downloaded.

Run the following command in the SSH terminal:

topio db download https://top-mainnet-space.nyc3.digitaloceanspaces.com/db_20220323_v3_ebc276e0d5ef0b0f37fe6313c36c7655.tar.gz

In the returned message, if the download progress is 100% and the following content is included, the database is downloaded.

download database ok.

md5sum check ok.

# 3. Configure Environment Variables (optional)

After TOPIO is installed, configure environment variables with the following command, to set "/opt/topnetwork" to your authority directory.

echo "export TOPIO_HOME=/opt/topnetwork" >> ~/.bashrc && source ~/.bashrc

If you do not configure environment variables, you will use the system default directory as the working directory of TOPIO:

For root user: the default directory is /root/topnetwork;
For non-root user: the default directory is /home/user/topnetwork, where user is your user name to log in to the server.
