centeros 6 远程升级ssl ssh 的shell脚本

变量说明

SSL_N=openssl-1.0.2p #ssl 版本
SSH_N=openssh-7.9p1 #ssh 版本
ZLIB_N=zlib-1.2.11 # zlib 版本

脚本分为两个，因为升级ssh ssh存在断开问题，需要临时启用telnet继续执行

yum配置采用了ftp yum源，具体配置见我的博客：

https://www.cnblogs.com/levi-w/p/9675157.html

执行步骤：

1 首先在服务器执行openssh-update.telnet.sh

2 telnet 登录服务器，执行openssh-update.sh

 

脚本详情：

1 openssh-update.telnet.sh

#!/bin/bash
#config yum
export SSL_N=openssl-1.0.2p
export SSH_N=openssh-7.9p1
export ZLIB_N=zlib-1.2.11

cp -r /etc/yum.repos.d /etc/yum.repos.d_bak
rm -rf /etc/yum.repos.d/*

echo "[CenterOS-source]
name=Linux "'$releasever'" - "'$basearch'" - Source
baseurl=ftp://10.1.1.1/pub/cos6
enabled=1
gpgcheck=0" > /etc/yum.repos.d/rhel-source.repo

yum makecache

yum -y install gcc* telnet* pam-devel openssl-devel

##config telnet#一定要测试！
yum -y install telnet*
# disable字段改为no
sed -i '12c disable = no' /etc/xinetd.d/telnet
service xinetd restart
mv /etc/securetty /etc/securetty.bak

read -p "test telnet[y/n]: " number
if [ $number != 'y' ]
then
echo "Error"
exit
fi
echo "please use telnet to countinue"

 

2 openssh-update.sh
