What Can I Do If the MySQL Database on the Standby Server Does Not Start After the Post-processing Script Is Executed in an OMMHA Incremental Two-Node Installation Scenario

What Can I Do If the MySQL Database on the Standby Server Does Not Start After the Post-processing Script Is Executed in an OMMHA Incremental Two-Node Installation Scenario

Question

What can I do if the MySQL database on the standby server does not start after the post-processing script (install_post.sh) is executed in an OMMHA incremental two-node installation scenario?

Answer

  1. Log in to the active server as the root user.
  2. Re-execute the pre-processing script install_pre.sh in the directory where the installation file is stored.

    # cd Installation file directory

    # sh install_pre.sh

  3. Re-execute the post-processing script install_post.sh in the directory where the installation file is stored.

    # sh install_post.sh

    If the following information is displayed, the MySQL database on the standby server is started properly:
