  • mysqlpump 和 mysql_config_editor测试

    The mysql_config_editor utility enables you to store authentication credentials in an obfuscated login path file named .mylogin.cnf. The file location is the %APPDATA%MySQL directory on Windows and the current user's home directory on non-Windows systems. The file can be read later by MySQL client programs to obtain authentication credentials for connecting to MySQL Server.

    The unobfuscated format of the .mylogin.cnf login path file consists of option groups, similar to other option files. Each option group in .mylogin.cnf is called a login path,” which is a group that permits only certain options: host, user, password, port and socket. Think of a login path option group as a set of options that specify which MySQL server to connect to and which account to authenticate as. Here is an unobfuscated example: (该工具的作用就是将mysql的登录凭证写到一个默认的.mylogin.cnf配置文件里,然后在执行命令mysql --login-path=mypath时,会使用该配置文件里的凭证自动登录)

    [client]
    user = mydefaultname
    password = mydefaultpass
    host = 127.0.0.1
    [mypath]
    user = myothername
    password = myotherpass
    host = localhost
    1. 设置MySQL免密码登录
    mysql_config_editor set --login-path=testlogin --user=root --host=localhost --password
    执行上面的命令后,mysql 会提示你输入root的密码。
    该命令会在root的home目录下创建一个.mylogin.cnf配置文件,内容为加密状态,包含上面的mysql登录时需要用到的帐号密码、服务器等。

    2. 创建备份脚本
    # vi testbackupdb.sh
    #!/bin/bash
    echo 'Begin Backup test DB'
    
    DATE1=`date -d "now" +%Y%m%d_%H%M%S`
    mysqlpump --login-path=testlogin --default-character-set=UTF8MB4 --single-transaction --compress-output=LZ4 --default-parallelism=3 -B testdb 
    --log-error-file=/root/db_backup/logs/testdb_bak_$DATE1.log >/root/db_backup/testdb_bak_$DATE1.sql.lz
    3. 添加定时任务
    # crontab -e
    01 02 * * * /root/db_backup/testbackupdb.sh
