基于备份恢复搭建Mysql主从

基于备份恢复搭建ERP主从
一. 复制备份文件到目标环境
mkdir -p /var/lib/mysql
lvcreate -n lv_data -L 2048G DATAVG
mkfs.ext4 /dev/mapper/DATAVG-lv_data 
mount /dev/mapper/DATAVG-lv_data /var/lib/mysql
mkdir -p  /var/lib/mysql/fullbackup
mkdir -p  /var/lib/mysql/increment
mkdir -p  /var/lib/mysql/binlog
scp root@192.168.5.3:/bak/mysql/db005036/archive/fullbackup_2018-09-02.tar.gz /var/lib/mysql/fullbackup/
scp -r root@192.168.5.3::/bak/mysql/db005036/increment/2018-09-05 /var/lib/mysql/increment/

二. 安装数据库等基础软件
cd /usr/local/
tar zxf mysql-5.5.61-linux-glibc2.12-x86_64.tar.gz 
mv mysql-5.5.61-linux-glibc2.12-x86_64.tar mysql
cp mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
 
三. 检查相关软件包
soft_check()
#检查Xtrabackup
{
echo "####################################################################################"
echo "$($Time) Check Installed SoftWare"
if dpkg -l|grep percona-xtrabackup-24;then
    echo "">/dev/null
else
    wget https://repo.percona.com/apt/percona-release_0.1-4.$(lsb_release -sc)_all.deb
    dpkg -i percona-release_0.1-4.$(lsb_release -sc)_all.deb
    apt-get update
    apt-get install percona-xtrabackup-24 -y
    Reval=$?
        if [ ${Reval} -eq 0 ];then
            echo "percona-xtrabackup-24 install sucess"
        else 
            echo "\033[41;37m [ERROR] \033[0m install failure"
            send_mes "percona-xtrabackup-24 install failure"
            exit 1
        fi
fi
#检测curl软件安装包
if dpkg -L  curl >/dev/null 2>&1;then
    echo "" >>/dev/null
else
apt-get update
apt-get install curl -y
fi
#检查qpress软件安装包
if which qpress;then
    echo "" >/dev/null
else
    wget http://www.quicklz.com/qpress-11-linux-x64.tar
    tar xvf qpress-11-linux-x64.tar
    cp qpress /usr/bin/
    Reval=$?
        if  [ ${Reval} -eq 0 ];then
            echo "qpress installl success"
        else
            echo "\033[41;37m [ERROR] \033[0m install failure"
            send_mes "qpress install faillure"
        fi
fi        
}

五. 恢复还原数据库
innobackupex --decompress   /var/lib/mysql/fullbackup  && { find  /var/lib/mysql/fullbackup    -name  '*.qp' -type f |xargs rm;  }
innobackupex --decompress   /var/lib/mysql/increment/2018-09-05 &&{ find  /bak/mysql/db005036/increment/2018-09-05    -name  '*.qp' -type f |xargs rm;}
innobackupex --apply-log    --redo-only  /var/lib/mysql/fullbackup
innobackupex --apply-log    --redo-only  /var/lib/mysql/fullbackup --incremental-dir=/var/lib/mysql/increment/2018-09-05
innobackupex --apply-log    /var/lib/mysql/fullbackup
mv /var/lib/mysql/fullbackup/* /var/lib/mysql/
chmod +x /var/lib/mysql
mysqld_safe --defaults-file=/etc/mysql/my.cnf --user=mysql &

六. 恢复二进制文
