1 #!/bin/bash 2 :<<! 3 注意： : %s/openssh-8.1p1/openssh-8.1p1/g 4 1.使用脚本前需要在命令行模式下更改文本模式set ff=unix ; 5 2. 执行完脚本后，请执行source /etc/profile; 6 3. 请在/root下执行脚本 7 4.如出现openssl升级后找不到库文件，可通过查找openssl库文件解决。//find / -name "libssl*” echo "/usr/local/lib64" >> /etc/ld.so.conf ldconfig -v 8 ! 9 10 system_init () { 11 sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/‘ /etc/selinux/config #//永久设置selinux为disabled状态 12 setenforce 0 #//手动设置selinux为Permissive 13 # sed -i ‘s/#Port 22/Port 22022‘ /etc/ssh/sshd_config #//如果需要更改远程端口，去掉前面注释并修改相应的端口 14 sed -i ‘s/#PermitRootLogin prohibit-password/PermitRootLogin yes/‘ /etc/ssh/sshd_config #//允许root用户远程登录，不允许yes改为no 15 sed -i ‘1a nameserver 114.114.114.114‘ /etc/resolv.conf #//添加NDS地址 16 sed -i ‘1a options timeout:1 attempts:1 rotate‘ /etc/resolv.conf #//设置超时时间和重试次数，加上这条可以解决dns解析慢的问题 17 echo root | passwd --stdin root 18 yum -y install wget net-tools httpd-tools sysstat lsof tree 19 if [ $?
