Centos设置limit最大打开文件数和最大进程数

在/etc/security/limits.conf添加

cat > /etc/security/limits.conf <<EOF

* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072

EOF

如果是cento6.x, /etc/security/limits.d/90-nproc.conf会覆盖/etc/security/limits.conf中的设置, 所以简单方法, 清空/etc/security/limits.d/90-nproc.conf

echo -n > /etc/security/limits.d/90-nproc.conf
