# 附录

附录：mysql参数sql_log_bin配置

如果想在主库上执行一些操作，但不复制到slave库上，可以通过修改参数sql_log_bin来实现。
比如说,模拟主从同步复制异常。
-- 在从库上执行
mysql> set sql_log_bin=0;#设为0后，在Master数据库上执行的语句都不记录binlog
mysql> delete from t1 where id = 3;
mysql> set sql_log_bin=1;
-- 要慎重使用global修饰符（set global sql_log_bin=0)，这样会导致所有在Master数据库上执行的语句都不记录到binlog，这肯定不是你想要的结果

# 环境：

/*
主库：10.192.30.53
从库：10.192.30.60
用户名：admin_m
密码：rA75MQy*R*y@KO4z%LZe
*/

# 创建同步复制账号

CREATE USER 'repl'@'10.192.30.%' IDENTIFIED WITH mysql_native_password BY 'DHTg9nRZ4AoRRV6BDQup';
GRANT REPLICATION SLAVE ON *.* TO 'repl'@'10.192.30.%';

# 一、基于GTID搭建复制

# 一、基于GTID搭建复制
-- 、备份主库
yum -y install lz4-devel
yum -y install lz4
mysqlpump -h 10.192.30.53 -P  -uadmin_m -p"rA75MQy*R*y@KO4z%LZe" --default-character-set=utf8mb4 -A --add-drop-database --add-drop-table --add-drop-user --add-locks -C --compress-output=LZ4 --default-parallelism= --events --hex-blob --log-error-file=/tmp/dump.err --max-allowed-packet= --routines --set-gtid-purged=ON --single-transaction --triggers  >/data/bak/all_dump_10.192.30..sql.lz4

# 解压

lz4 -d all_dump_10.192.30..sql.lz4 > all_dump_10.192.30..sql

# 传输至从库

scp all_dump_10.192.30..sql 10.192.30.60:/opt/

# 导入到从库

mysql> reset slave all; reset master;

mysql -h 10.192.30.60 -P 3306 -uadmin_m -p"rA75MQy*R*y@KO4z%LZe" --default-character-set=utf8mb4  < all_dump_10.192.30.53.sql

change master to master_host = '10.192.30.53', master_port = 3306, master_user = 'repl', master_password = 'DHTg9nRZ4AoRRV6BDQup', master_auto_position = 1;
start slave;
show slave status\G;

至此主从复制搭建完毕。

# 二、GTID运维

传统基于二进制坐标的复制中，从库由于某些错误导致复制中断时，一个可能的解决方案是设置sql_slave_skip_counter全局系统变量，
跳过导致错误的事件，然后重启复制。但启用GTID后，执行的单位由事件变为事务，因此该方法不再有效。

mysql> set global sql_slave_skip_counter=1;
ERROR 1858 (HY000): sql_slave_skip_counter can not be set when the server is running with @@GLOBAL.GTID_MODE = ON. Instead, for each transaction that you want to skip, generate an empty transaction with the same GTID as the transaction
mysql>

　　从错误消息可以看到，GTID跳过事务的方法是注入一个空事务，具体步骤为：
（1）定位出错事务的GTID。
     从库报错我们需要获得从库执行的最后一个事务，方法有：

show slave status \G 中的 Executed_Gtid_Set;
show global variables like '%gtid%'; # gtid_executed
show master status; # 中的Executed_Gtid_Set。

（2）将会话级系统变量gtid_next设置为上一步的GTID，如。

stop slave;
set gtid_next='46760eb0-bcb3-11e9-a352-24a9c4e7e87e:73'; # Retrieved_Gtid_Set: 46760eb0-bcb3-11e9-a352-24a9c4e7e87e:66-73
begin;
commit;
set GTID_NEXT='AUTOMATIC';
start slave;
