Question

centos7安装oracle11g需要关闭防火墙吗

Answer 1

// 注释 # root用户 $oracle用户
1. 关闭安全措施

# chkconfig iptables off // 永久关闭防火墙
# serviceiptables stop // 暂时关闭防火墙，重启系统后会自动打开
# sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config // 关闭Selinux

2. 验证硬件

要求：内存最小1G，推荐2G或者更高。
查看命令：# grep MemTotal /proc/meminfo

16G以上 16G
查看命令：# grep SwapTotal /proc/meminfo
# free
