总括：
模拟从库故障，从主库备份数据恢复从库，把主库数据远程备份到从库。
1.主从库安装xtrabackup工具
#安装依赖
sudo yum install perl-DBI perl-DBD-MySQL perl-IO-Socket-SSL perl-Digest-MD5 perl-TermReadKey qpress
#依赖包下载地址
https://repo.percona.com/yum/release/7/RPMS/x86_64/
rpm -ivh percona-xtrabackup-24-2.4.29-1.el7.x86_64.rpm
2.备份并释放流文件:
若未配置ssh免登录：
nohup innobackupex --defaults-file=/opt/mysql/etc/3310/my.cnf -uroot -p'P@ssw0rd' -S /opt/mysql/data/3310/mysqld.sock --stream=xbstream --compress --compress-threads=16 /opt/mysql/data/3310/ |sshpass -p'rootroot' ssh root@10.186.57.34 "xbstream -x -C /data/xbstream" > /soft/backup.log 2>&1 &
若配置ssh免密登录：
nohup innobackupex --defaults-file=/opt/mysql/etc/3310/my.cnf -uroot -p --socket=/opt/mysql/data/3310/mysqld.sock --stream=xbstream --compress --compress-threads=8 /opt/mysql/data/3310/ | ssh root@10.186.57.34 'xbstream -x -C /data/xbstream' > /soft/backup.log 2>&1 &
3.解压:
xtrabackup --parallel=8 --decompress --remove-original --target-dir=/data/xbstream/
4.恢复:
#清理/opt/mysql/etc/3310/my.cnf内数据目录和redolog目录数据
apply-log
innobackupex --defaults-file=/opt/mysql/etc/3310/my.cnf --parallel=4 --apply-log /data/xbstream/
##/opt/mysql/etc/3310/my.cnf 可以是故障从库的配置文件
copy-backup
xtrabackup --defaults-file=/opt/mysql/etc/3310/my.cnf --copy-back --target-dir=/data/xbstream/
5.修改数据目录和redolog目录属主
chown -R mysql.mysql /data
chown -R mysql.mysql /redolog
6.启动从库mysql服务
/opt/mysql/base/8.0.28/bin/mysqld --defaults-file=/opt/mysql/etc/3310/my.cnf --daemonize --pid-file=/opt/mysql/data/3310/mysqld.pid --user=actiontech-mysql --socket=/opt/mysql/data/3310/mysqld.sock --port=3310
7.建立复制
[root@localhost xbstream]# cat xtrabackup_binlog_info
mysql-bin.000010 184074483 304e4a27-33ed-11ef-91b7-02000aba3b26:1-25571
change replication source to
source_host='10.186.59.38',
source_port=3310,
source_user='repl',
source_password='P@ssw0rd',
source_log_file='mysql-bin.000010',
source_log_pos=184074483;
start replica;
show replica status \G;
8.等待主从数据追平1.安装xtrabackup工具
#安装依赖
sudo yum install perl-DBI perl-DBD-MySQL perl-IO-Socket-SSL perl-Digest-MD5 perl-TermReadKey qpress
#依赖包下载地址
https://repo.percona.com/yum/release/7/RPMS/x86_64/
[root@localhost soft]# rpm -ivh percona-xtrabackup-24-2.4.29-1.el7.x86_64\ \(1\).rpm

[root@localhost soft]# wget https://repo.percona.com/yum/release/7/RPMS/x86_64/qpress-11-3.el7.x86_64.rpm
2.备份并释放流文件
nohup bash -c 'innobackupex --defaults-file=/opt/mysql/etc/3310/my.cnf -uroot -p"P@ssw0rd" -S /opt/mysql/data/3310/mysqld.sock --stream=xbstream --compress --compress-threads=8 /opt/mysql/data/3310/ |sshpass -p'rootroot' ssh root@10.186.57.34 "xbstream -x -C /data/xbstream"' > /soft/xtrabackup.log 2>&1 &
##备份命令说明
1.compress压缩，开启8个压缩线程（可视数据库负载大小调整），压缩率可达70%，500G压缩至130G.
2.|sshpass -p'rootroot' 可实现远程备份到目标服务器，若两台服务器配置了ssh免密登录，则可去除sshpass -p'rootroot'。
3.备份命令后台运行，可在/soft/xtrabackup.log查看备份进度和信息。
