搭建wordpress个人博客之(4)备份数据库并发送邮件

1、下载sendEmail

#下载安装包
wget http://caspian.dotconf.net/menu/Software/SendEmail/sendEmail-v1.56.tar.gz
#创建目录
mkdir -p /usr/local/bin
#解压
tar zxf sendEmail-v1.56.tar.gz -C /usr/src/
#进入解压目录
cd /usr/src/sendEmail-v1.56/
#复制程序到指定目录
cp -a sendEmail /usr/local/bin/
#给执行权限
chmod +x /usr/local/bin/sendEmail
#安装组件
yum install perl-Net-SSLeay perl-IO-Socket-SSL -y

2、发送邮件脚本（注意:相关数据进行了打码）:

#邮件发送脚本
#!/bin/bash

#收件人邮箱
EMAIL_RECIVER="xxx@qq.com"
#发送人邮箱
EMAIL_SENDER=xxx@sina.cn
#邮箱用户名
EMAIL_USERNAME=xxx@sina.cn
#邮箱密码,非账户密码，是开启smtp服务的授权码
#使用qq邮箱进行发送需要注意：首先需要开启：POP3/SMTP服务，其次发送邮件的密码需要使用在开启POP3/SMTP服务时候腾讯提供的第三方客户端登陆码。
EMAIL_PASSWORD=xxxx

#附件路径
FILE1_PATH="/home/xxx/bakup/bak/mysql/$1/blog.sql"
FILE2_PATH="/home/xxx/tools/readme.md"

#smtp服务器地址
EMAIL_SMTPHOST=smtp.sina.cn

EMAIL_TITLE="数据库备份"
EMAIL_CONTENT="数据库备份成功，已上传!"

echo '开始发送邮件'
/home/shares/tools/sendEmail-v1.56/sendEmail -f ${EMAIL_SENDER} -t ${EMAIL_RECIVER} -s ${EMAIL_SMTPHOST} -u ${EMAIL_TITLE} -xu ${EMAIL_USERNAME} -xp ${EMAIL_PASSWORD} -m ${EMAIL_CONTENT} -a ${FILE1_PATH} ${FILE2_PATH} -o message-charset=utf-8 -l /home/shares/bakup/logs/sendEmail.log
echo '结束发送邮件'

3、运行报错信息:

*******************************************************************
 Using the default of SSL_verify_mode of SSL_VERIFY_NONE for client
 is deprecated! Please set SSL_verify_mode to SSL_VERIFY_PEER
 possibly with SSL_ca_file|SSL_ca_path for verification.
 If you really don't want to verify the certificate and keep the
 connection open to Man-In-The-Middle attacks please set
 SSL_verify_mode explicitly to SSL_VERIFY_NONE in your application.
*******************************************************************
  at /usr/local/bin/sendEmail line 1906.
invalid SSL_version specified at /usr/xxx/perl5/vendor_perl/IO/Socket/SSL.pm line 444.

错误原因：
centos7.3默认的Perl版本是5.16，使用sendEmail-v1.56似乎要使用5.10版本的Perl才能够成功发送邮件。

4、下载正确的版本:

wget http://www.cpan.org/src/5.0/perl-5.10.0.tar.gz
tar zxf perl-5.10.0.tar.gz
cd perl-5.10.0
./configure.gnu -des -Dprefix=/usr/local/perl
echo $?    #返回0，编译没问题
make
make test
make install
备份原来的Perl
mv /usr/bin/perl /usr/bin/perl.bak
ln -s /usr/local/perl/bin/perl /usr/bin/perl

5、查看Perl版本，显示5.10表示已经成功

[root@yarcl bakup]# perl -v

6、执行脚本命令

[root@yarcl bin]# ./sendEmail.sh 20200110
开始发送邮件
Jan 10 20:11:25 xxx sendEmail[30427]: Email was sent successfully!  From: <xxxx@sina.cn> To: <xxxx@qq.com> Subject: [数据库备份] Attachment(s): [blog.sql] [readme.md] Server: [smtp.sina.cn:25]
结束发送邮件
