新装的系统有不少东西需要优化和安装，通过终端敲命令过于浪费时间，干脆写成一个简单的小脚本供自己以后使用，其中有些配置需要根据环境环境修改。
systemctl disable firewalld sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config rm -rf /etc/yum.repos.d/* mkdir .ssh && chmod 700 .ssh curl http://10.0.0.102/authorized_keys > .ssh/authorized_keys && chmod 600 .ssh/authorized_keys curl http://10.0.0.102/centos7.repo > /etc/yum.repos.d/centos7.repo curl http://10.0.0.102/epel.repo > /etc/yum.repos.d/epel.repo curl http://10.0.0.102/resolv.conf > /etc/resolv.conf curl http://mirrors.ustc.edu.cn/epel/RPM-GPG-KEY-EPEL-7 > /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 curl http://10.0.0.102/ntp.conf > /etc/ntp.conf curl http://10.0.0.102/hosts > /etc/hosts yum makecache yum -y install vim wget lrzsz bmon python-pip net-tools ntp dstat yum -y update systemctl enable ntpd chmod 777 /etc/rc.d/rc.local sed -i -e '129s/#/ /g' /etc/ssh/sshd_config sed -i -e '129s/yes$/no/g' /etc/ssh/sshd_config sed -i '/^GSS/s/yes/no/g' /etc/ssh/sshd_config ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime timedatectl set-local-rtc 1 clock -w reboot
这个简陋的小脚本先这样用着，等以后有需求了再慢慢修改、优化。
