安裝與設定 AutoMySQLBackup

  • 安裝環境 : CentOS 6.9 x86_64
  • 安裝版本 : automysqlbackup-v3.0_rc6
  • su - root
    mkdir -p source/automysqlbackup
    cd source/automysqlbackup
    wget https://nchc.dl.sourceforge.net/project/automysqlbackup/AutoMySQLBackup/AutoMySQLBackup%20VER%203.0/automysqlbackup-v3.0_rc6.tar.gz
    tar -zxvf automysqlbackup-v3.0_rc6.tar.gz
    ./install.sh
  • 如果都採用預設值, 設定檔將會安裝至 /etc/automysqlbackup/ , 執行檔將會安裝至 /usr/local/bin/
  • 更改 /etc/automysqlbackup/myserver.conf 成為符合自己環境的設定 Exp.
    :
    CONFIG_mysql_dump_username='root'
    
    CONFIG_mysql_dump_password='xxxx'
    
    CONFIG_mysql_dump_host='localhost'
    
    CONFIG_backup_dir='/backup/db'
    
    :
  • 第一次手動執行
    automysqlbackup /etc/automysqlbackup/myserver.conf
  • 設定每天自動執行
    vi /etc/cron.daily/runmysqlbackup
    #!/bin/sh
    
    /usr/local/bin/automysqlbackup /etc/automysqlbackup/myserver.conf
    
    chown root.root /var/backup/db* -R
    find /var/backup/db* -type f -exec chmod 400 {} \;
    find /var/backup/db* -type d -exec chmod 700 {} \;
    chmod a+x /etc/cron.daily/runmysqlbackup
    service crond restart
  • 安裝 pigz 來解決
    yum install pigz
  • 參數檔內的 CONFIG_mysql_dump_single_transaction 設為'yes' 來解決
    :
    # While a --single-transaction dump is in process, to ensure a valid dump file (correct table contents and
    # binary log coordinates), no other connection should use the following statements: ALTER TABLE, CREATE TABLE,
    # DROP TABLE, RENAME TABLE, TRUNCATE TABLE. A consistent read is not isolated from those statements, so use of
    # them on a table to be dumped can cause the SELECT that is performed by mysqldump to retrieve the table
    # contents to obtain incorrect contents or fail.
    CONFIG_mysql_dump_single_transaction='yes'
