Linux openssh8.0p1升级步骤(shell版本)

运维自动化时代,手动升级太徒劳了,为了提高效率及准确率,自动化安装是必备的。

下面是通过shell写的脚本。也可以将其应用到ansible上.

准备好安装文件:

openssh-8.0p1.tar.gz

openssl-1.1.0k.tar.gz 

zlib-1.2.11.tar.gz

openssl-fips-2.0.16.tar.gz

perl-5.10.0.tar.gz(redhat5以下需要,由于编辑openssl,perl版本最底为5.10.0)

脚本内容如下:

#!/bin/bash
#
#setup && update openssh8.0p1

#Action state
mstate(){
    if [ $? -eq 0 ];then
        echo "--------------------------By installing--------------------------"
    else
    echo "--------------------------Installation failed--------------------"
        exit 1
    fi
}

    cd $MDIR
    tar -xzvf zlib-1.2.11.tar.gz >> /dev/null
