Problem:the kernel parameters does not meet the minimum requirements.

Recommendation:perform operating system Specific instructions to update the kernel parameters.

Modify the/etc/sysctl.conf kernel configuration file, add/modify the following items, if not added yourself

Kernel.shmall = 2097152 # The total amount of shared memory that can be used.

Kernel.shmmax = 2147483648 # maximum shared memory segment size.

Kernel.shmmni = 4096 # maximum number of shared memory segments across the system.

Kernel.sem = 250 32000 100 128 # The maximum number of signal objects per signal object Set, the maximum number of signal objects in the system range, the maximum operand supported by each signal object, and the maximum number of signal object sets in the system range.

Fs.file-max = 65536 # The maximum number of file handles allowed in the system.

Net.ipv4.ip_local_port_range = 1024 65000 # IPV4 port range that the application can use.

Net.core.rmem_default = 4194304 # socket receives the default value of the buffer size

Net.core.rmem_max = 4194304 # Socket receive buffer size maximum

Net.core.wmem_default = 262144 # socket send buffer size default value

Net.core.wmem_max = 262144 # socket send buffer size maximum

Run the following command to make the kernel parameters effective:

/sbin/sysctl–p
