2. Modify core operating system parameters

Perform the following steps under the Root user:

1) modify the user's SHELL restrictions and modify the/etc/security/limits. conf file

Enter the command vi/etc/security/limits. conf, press the I key to enter the editing mode, and add the following content to the file.

Oracle soft nproc 2047 Hard nproc 16384 Oracle soft nofile 1024 Oracle hard nofile 65536

After editing, Press Esc and enter ": wq" to save the disk and exit.

 

2) modify the/etc/pam. d/login file, enter the command vi/etc/pam. d/login, press the I key to enter the editing mode, and add the following content to the file.

Session required/lib/security/pam_limits.so Session required pam_limits.so

After editing, Press Esc and enter ": wq" to save the disk and exit.

 

3) modify the Linux kernel, modify the/etc/sysctl. conf file, enter the command vi/etc/sysctl. conf, press the I key to enter the editing mode, and add the following content to the file.

Fs. file-max = 6815744 Fs. aio-max-nr = 1048576 Kernel. shmall = 2097152 Kernel. shmmax = 2147483648 Kernel. shmmni = 4096 Kernel. sem = 250 32000 100 128 Net. ipv4.ip _ local_port_range = 9000 65500 Net. core. rmem_default = 4194304 Net. core. rmem_max = 4194304 Net. core. wmem_default = 262144 Net. core. wmem_max = 1048576

After editing, Press Esc and enter ": wq" to save the disk and exit.

 

4) to make the/etc/sysctl. conf change take effect immediately, run the following command. Input: sysctl-p:

Linux :~ # Sysctl-p Net. ipv4.icmp _ echo_ignore_broadcasts = 1 Net. ipv4.conf. all. rp_filter = 1 Fs. file-max = 6815744 Fs. aio-max-nr = 1048576 Kernel. shmall = 2097152 Kernel. shmmax = 2147483648 Kernel. shmmni = 4096 Kernel. sem = 250 32000 100 128 Net. ipv4.ip _ local_port_range = 9000 65500 Net. core. rmem_default = 4194304 Net. core. rmem_max = 4194304 Net. core. wmem_default = 262144 Net. core. wmem_max = 1048576
