Linux操作系统安装完成上线前后序操作

1、关闭防火墙及Selinux
[root@localhost ~]# chkconfig iptables off && service iptables stop && chkconfig ip6tables off && service ip6tables stop && iptables -F && iptables -X && iptables -Z && sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config && setenforce 0

2、修改网络时钟服务器
[root@localhost ~]# grep -n server /etc/ntp.conf

3、配置本地及网络yum源
RHEL/CentOS 6.8本地源:
[root@localhost ~]# mkdir /mnt/cdrom && echo "/dev/sr0 /mnt/cdrom iso9660 defaults 0 0" >> /etc/fstab && mount -a
rm -rf /etc/yum.repos.d/*
cat > /etc/yum.repos.d/rhel6.repo << EOF [rhel6 - Server] name=rhel6-Server baseurl=file:///mnt/cdrom enabled=1 gpgcheck=0 [HighAvailability] name=rhel6-source baseurl=file:///mnt/cdrom/HighAvailability enabled=1 gpgcheck=0 [rhel6-LoadBalancer] name=rhel6-source baseurl=file:///mnt/cdrom/LoadBalancer enabled=1 gpgcheck=0 [rhel6-ResilientStorage] name=rhel6-source baseurl=file:///mnt/cdrom/ResilientStorage enabled=1 gpgcheck=0 [rhel6-ScalableFileSystem] name=rhel6-source baseurl=file:///mnt/cdrom/ScalableFileSystem enabled=1 gpgcheck=0 EOF RHEL/CentOS 6.8网络源: 163源: [root@localhost ~]# wget -O /etc/yum.repos.d/CentOS6-Base-163.repo http://mirrors.163.com/.help/CentOS6-Base-163.repo && sed -i 's/$releasever/6.9/g' /etc/yum.repos.d/CentOS6-Base-163.repo && sed -i 's/gpgcheck=1/gpgcheck=0/g' /etc/yum.repos.d/CentOS6-Base-163.repo Aliyun源: [root@localhost ~]# wget -O /etc/yum.repos.d/CentOS6-Base-aliyun.repo http://mirrors.aliyun.com/repo/Centos-6.repo && sed -i 's/$releasever/6.9/g' /etc/yum.repos.d/CentOS6-Base-aliyun.repo && sed -i 's/gpgcheck=1/gpgcheck=0/g' /etc/yum.repos.d/CentOS6-Base-aliyun.repo idc源: [root@localhost ~]# cat > /etc/yum.repos.d/CentOS6-Base-idc.repo <
