客户系统检测出openssh版本过旧存在漏洞，所以决定写个脚本，需要四个包：openssh-7.1p2.tar，openssl-1.0.1s.tar，telnet-server-1.2-149.1.x86_64，zlib-1.2.8.tar
脚本如下：（亲测，可用）
#!/bin/bash
#program : Server auto deploy
#author : [email protected]
#version : latst
#function : update openssh
##当前路径
current_dir="$(pwd) "
zlib_version="zlib-1.2.8"
openssh_version="openssh-7.1p2"
openssl_version="openssl-1.0.1s"
DATE=`date +%Y%m%d`
Distributor=`lsb_release -i|cut -c 17-`
BLUE_COLOR=‘\E[1;34m‘ #蓝
RED_COLOR=‘\E[1;31m‘ #红
BLACK_COLOR=‘\E[1;30m‘ #黑
echo -e "${RED_COLOR}########################################################################################${RES}"
echo -e "${RED_COLOR}################### #################### "
echo -e "${RED_COLOR}################### openssh install -----[success] #################### "

echo -e "${RED_COLOR}################### #################### "
echo -e "${RED_COLOR}########################################################################################${RES}"
echo -e "${BLACK_COLOR} ${RES}"
sleep 5
##检查系统当前用户
if [ `id -u` != 0 ]; then
echo "Error: if you want to run this script,please use root to execute;"
exit 1
fi
##安装telnet
cd $current_dir
rpm -ivh telnet-server-1.2-149.1.x86_64.rpm
sed -e ‘s/yes/no/g‘ /etc/xinetd.d/telnet
/etc/init.d/xinetd restart
chkconfig --list | grep telnet
if [ $? -eq 0 ]; then
echo "install telnet ---------------------------[success]"
fi
sleep 5
##记录当前openssh版本信息
cd $current_dir
touch openssh_version.txt > /dev/null
echo `ssh -V` &> $current_dir/openssh_version.txt
##安装zlib,构建共享库
cd $current_dir
tar -zxvf zlib-1.2.8.tar.gz
cd $zlib_version
./configure --shared
sleep 3
/usr/bin/make install
cp zutil.h /usr/local/include
cp zutil.c /usr/local/include
/sbin/ldconfig -v
sleep 2
##进入安装包上传目录，解压openssl
cd $current_dir
tar -zxvf openssl-1.0.1s.tar.gz
cd $openssl_version
./config shared zlib
sleep 3
/usr/bin/make
sleep 2
/usr/bin/make install
echo "install openssl --------------------------[success]"
sleep 5
##修改配置文件，显示正常版本信息
mv `which openssl` /usr/bin/openssl.bak
ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
echo `ssh -V` &> /$current_dir/openssh_version.txt
echo "/usr/local/ssl/lib" >> /etc/ld.so.conf
/sbin/ldconfig -v
##软件安装之-Openssh安装
##禁用sshd服务，卸载原来的openssh版本
/sbin/service sshd stop
cp /etc/init.d/sshd /root/
if rpm -qa | grep openssh &> /dev/null
then
rpm -qa | grep openssh &> $current_dir/openssh_version.txt
while read line
do
rpm -e $line --nodeps
echo "remove $line ------------------------------[success]"
done <$current_dir/openssh_version.txt
fi
##解压缩openssh安装包，并进入解压缩文件编译安装
cd $current_dir
tar -zxvf openssh-7.1p2.tar.gz
cd $openssh_version
./configure --prefix=/usr --with-zlib=/root/zlib-1.2.8 --with-md5-passwords
sleep 2
/usr/bin/make
sleep 2
/usr/bin/make install
##启动调试ssh
#OS type

cp rc.sshd /etc/init.d/sshd
chmod +x /etc/init.d/sshd
