I have Installed and worked with MemSQL on Ubuntu 12.04 and CentOS 6. But I am doing a fresh install on CentOs 6.4 (FInal). When running ./check_system script I am getting the following error.
Warning: The number of allowed open file descriptors should be at least 64000. This OS is currently configured with the limit set to 1024. Please visit http://developers.memsql.com/docs/2.5/admin/admin_concepts.html#configuring-the-linux-file-descriptor-limit
./check_system: line 313: 6173 Illegal instruction (core dumped) $SCRIPT_DIR/lib/check_crc32 > /dev/null 2> /dev/null Warning: SSE4.2 is not supported. Resorting to software CRC32C. MemSQL recovery and log writing performance will be negatively impacted.
I am familiar with the warning and I know how to fix it. its the Illegal instructions error I am trying to understand.
Any help in this regard will be useful.
For the file descriptor warning, you can either read that link, or simply use the rpm or deb package to install - both of these will configure that limit for you.
The warning about SSE4.2 is not a fatal warning - the server will run fine, generally with single-digit percentage slowdown to insert and update queries.
