1.安装msmtp
wget https://nchc.dl.sourceforge.net/project/msmtp/msmtp/1.6.6/msmtp-1.6.6.tar
tar xf msmtp-1.6.6.tar.xz && cd msmtp-1.6.6 && ./configure --prefix=/usr/local/msmtp --sysconfdir=/usr/local/msmtp/etc --with-ssl=openssl && sudo make && sudo make install
2. msmtp 配置
vi ~/.msmtprc
account default port 465 host smtp.163.com user 1367xxxx from 1367xxxx@163.com password xxx auth login tls on tls_starttls off tls_certcheck off logfile ~/.msmtp.log
这里要去163邮箱开通smtp，设置授权密码。这边用的是ssl的，所以端口是465. 所以在安装的时候，选择了ssl。如果电脑没有安装openssl，要先安装。
3. mutt 安装
sudo apt-get install mutt
4. mutt 配置
vi ~/.muttrc
set sendmail="/usr/bin/msmtp" set use_from=yes set realname="X" set from=1367xxxx@163.com set envelope_from=yes
5. 备份mysql 脚本
vi mysql_backup_script.sh
#!/bin/bash number=31 backup_dir=/home/ubuntu/mysqlbackup dd=`date +%Y-%m-%d-%H-%M-%S` tool=mysqldump username=root password=xxxx database_name=blog if [ ! -d $backup_dir ]; then mkdir -p $backup_dir; fi $tool -u $username -p$password $database_name > $backup_dir/$database_name-$dd.sql echo "mysql backup"|mutt 513431300@qq.com -s "mysql backup" -a $backup_dir/$database_name-$dd.sql echo "create $backup_dir/$database_name-$dd.dupm" >> $backup_dir/log.txt delfile=`ls -l -crt $backup_dir/*.sql | awk '{print $9 }' | head -1` count=`ls -l -crt $backup_dir/*.sql | awk '{print $9 }' | wc -l` if [ $count -gt $number ] then rm $delfile echo "delete $delfile" >> $backup_dir/log.txt fi
chmod +x mysql_backup_script.sh
6. crontab 定时设置任务
0 12 * * * /home/ubuntu/mysql_dump/mysql_backup_script.sh
