问题

The gateway process fails to start after the Tableau Server Upgrade (Linux version).

We can find the following error from the startup log of Apache.
Log File: <data>/tabsvc/logs/httpd/startup.log

Log Error Message:(38)Function not implemented: AH00141: Could not initialize random number generator

环境

Tableau Server
CentOS 7

解决方案

After confirming the error message, please try to "sudo yum update" to update the Linux kernel.
1. tsm stop.
2. sudo yum update (each node)
3. tsm start

原因

Apache cannot start due to the kernel version being too old. This issue may also occur upon new installation of Tableau Server if the kernel version is old.

其他信息

1. We recommend running "yum update" before upgrading the Tableau Server. Please take a system backup if necessary.
Please refer to more details in Single-Server Upgrade -- Run Setup

2. Run the command "name -a" to confirm the current Kernel version in Redhat Enterprise Linux/CentOS

3. Kernel Version History.
