             Summary: Bad interpret of iotdb-env.sh causing somaxconn warning failed
                 Key: IOTDB-1674
                 URL: https://issues.apache.org/jira/browse/IOTDB-1674
             Project: Apache IoTDB
          Issue Type: Improvement
          Components: Others
            Reporter: Eric Pai
            Assignee: Eric Pai
             Fix For: master branch


See the code of iotdb-env.sh

[https://github.com/apache/iotdb/blob/b76a799c4346ba16caf468e0c8f191949ff612b4/server/src/assembly/resources/conf/iotdb-env.sh#L39]

I have tested in my MacBook and a Linux virtual machine, the command outputs are:

Linux

 
{code:java}
[root@a0933215a07b iotdb]# sysctl net.core.somaxconn
net.core.somaxconn = 128
{code}
MacOS
{code:java}
[myuser iotdb]# sysctl kern.ipc.somaxconn
kern.ipc.somaxconn: 128 
{code}
 Here we can see using awk '\{print $2}' will get '=' in Linux, casuing the condition check failed.

The best solution is using sysctl *-n* option directly:

Linux
{code:java}
[root@a0933215a07b iotdb]# sysctl -n net.core.somaxconn
128
{code}
MacOS
{code:java}
[myuser iotdb]# sysctl -n kern.ipc.somaxconn
128 
{code}
