This article introduces the knowledge of "can SAC be installed separately?". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

[problem description]

The user installs the cluster through rapid deployment without installing the SAC service. So can I install the SAC service separately?

[solution]

Execute the command "ps-ef | grep sdbom" on all machines in the cluster to see if there are SAC service processes on the machine. If the cluster is started through rapid deployment, there should be no such process. After confirming that there are no SAC service processes, perform the following steps:

1. Start the SAC service process and execute the command in sdb shell:

> var oma = new Oma ("localhost", 11790)

> oma.createOM (11780, "/ opt/sequoiadb/database/sms/11780", {httpname: 8000, wwwpath: "/ opt/sequoiadb/web"})

> oma.startNode (11780)

two。 Copy the sequoiadb.xxx.run package and sequoiasql.xxx.run package to the directory "/ opt/sequoiadb/packet" and give them readable permissions

3. At this point, the SAC service process is ready for the web-side operation. The SAC service process only needs to run on a single machine, and it is not currently distributed

SAC is installed separately. The SequoiaDB storage service can be found before version 3.0, but the SQL instance cannot be found. The feature of discovering SQL instance is not available until version 3.2.2.
