Posted 2020-09-26

1、安装xtrabackup

cd /usr/local/

tar xvf percona-xtrabackup-2.0.8-587.tar.gz

mv percona-xtrabackup-2.0.8 xtrabackup

vim /root/.bash_profile

PATH=$PATH:$HOME/bin:/usr/local/xtrabackup/bin

source /root/.bash_profile 

2、全量备份mysql 5.1.73数据库

innobackupex --user=root --password=****** --socket=/var/lib/mysql/mysql.sock /root

3、安装 mysql 5.6.36

yum install -y autoconf automake imake libxml2-devel expat-devel cmake gcc gcc-c++ libaio libaio-devel bzr bison libtool ncurses5-devel

groupadd -r mysql

useradd -r -g mysql mysql

tar zxf mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz -C /usr/local/

cd /usr/local/

ln -s mysql-5.6.26-linux-glibc2.5-x86_64/ mysql

mkdir /mysqldata

chown -R mysql.mysql /mysqldata/

cd mysql

chown -R root.mysql ./*

scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data

cp support-files/mysql.server /etc/init.d/mysqld

chkconfig --add mysqld

vim /etc/profile.d/mysql.sh

    export PATH=$PATH:/usr/local/mysql/bin

. /etc/profile.d/mysql.sh 

service mysqld start

vim my.cnf 

    datadir = /mysqldata

    socket = /tmp/mysql.sock

service mysqld start

mysql_secure_installation

mysql -u root -p

4、使用xtrabackup还原数据库

service mysqld start

mv /usr/local/mysql/data/* /tmp

innobackupex --socket=/tmp/mysql.sock --apply-log /root/2017-07-04_10-41-46

innobackupex --socket=/tmp/mysql.sock --defaults-file=/usr/local/mysql/my.cnf --copy-back /root/2017-07-04_10-41-46

chown -R mysql.mysql /usr/local/mysql/data

service mysqld restart
