shell脚本——检测SSL证书过期时间

2019独角兽企业重金招聘Python工程师标准>>>

        说明：

                1、测试了阿里和又拍云的，虽然有某域名的证书了，但是输出结果却不是购买的证书信息，所以，如果有做cdn，则加host进行检测的，没有就无所谓了。

又拍云cdn测试信息

Validity             Not Before: Nov 14 00:00:00 2016 GMT             Not After : Dec 12 23:59:59 2017 GMT         Subject: C=CN, ST=zhejiang, L=hangzhou, O=Hangzhou Weiju Network Ltd., OU=\xE6\x8A\x80\xE6\x9C\xAF\xE9\x83\xA8, CN=*.upaiyun.com

                2、这里只是单域名检测，多域名，可以加上for循环。

                3、提醒方式，自由发挥。

Shell

#!/bin/bash domain_name="statics.perofu.com" ssl_port="443" #no cdn host="8.8.8.8 statics.perofu.com" grep -q "${host}" /etc/hosts || echo "${host}" >> /etc/hosts ping -c1 114.114.114.114 &> /dev/null if [ $? -eq 0 ] then         ssl_date=$(echo |openssl s_client -connect ${domain_name}:${ssl_port} 2>&1 |sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'|openssl x509 -text)         echo "${ssl_date}" | grep 'Subject: CN' | grep -q "${domain_name}"         if [ $? -eq 0 ]         then                 tmp_last_date=$(echo "${ssl_date}" | grep 'Not After :' | awk -F' : ' '{print $NF}')                 last_date=$(date -ud "${tmp_last_date}" +%Y-%m-%d" "%H:%M:%S)                 day_count=$(( ($(date -d "${last_date}" +%s) - $(date +%s))/(24*60*60) ))                 echo -e "\e[40;33;1m The [${domain_name}] out of date is : ${last_date} && [${day_count}] \e[0m"         else                 echo -e "\e[40;31;1m check ssl info isn't the [${domain_name}] ,please check ... \e[0m"         fi else         echo -e "\e[40;31;1m network is down ... \e[0m" fi

shell输出结果

The [statics.perofu.com] out of date is : 2018-05-10 23:59:59 && [343]
