二.系统体检
#!/bin/bash echo "系统内存大小：" free -g |grep ‘Mem‘ |awk ‘{print $2}‘ echo "系统cpu核数："
lscpu |grep ‘^CPU(s):‘ |awk ‘{print $2}‘ cat /proc/cpuinfo | grep "physical id" |wc -l
三.系统初始化
#!/bin/bash cp /etc/security/limits.conf /etc/security/limits.conf.bak.install.glc echo "# init by igoodful, 32cpu，128G memory" > /etc/security/limits.conf echo "* hard nofile 300000" >> /etc/security/limits.conf echo "* soft nofile 150000" >> /etc/security/limits.conf echo "* hard nproc 3000000" >> /etc/security/limits.conf echo "* soft nproc 1500000" >> /etc/security/limits.conf echo "* soft core unlimited" >> /etc/security/limits.conf
cp /etc/sysctl.conf /etc/sysctl.conf.bak.install.glc
echo "# init by igoodful 32cpu 128G memory" > /etc/sysctl.conf
