一、下载安装，在mysql主和从上面安装
1、下载mysql
cd /usr/local/src
wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.14.tar.gz
tar -zxvf mysql-5.6.14.tar.gz
cd mysql-5.6.14
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql5.6 -DMYSQL_DATADIR=/data/mysql5.6/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci
make && make install
二、创建数据目录配置文件
1、初始化工作
mkdir -p /data/mysql5.6/data
useradd mysql -s /sbin/nologin
passwd mysql
chown -R mysql.mysql /data/mysql5.6
cd /usr/local/mysql.5.6/
cp support-files/my-default.cnf /etc/my.cnf
cp support-files/mysql.server /etc/init.d/mysqld
ln -s ./bin* /usr/local/bin
./scripts/mysql_install_db --basedir=/usr/local/mysql5.6/ --datadir=/data/mysql5.6/data/ --user=mysql
三、mysql主配置
1、配置文件
shell>vim /etc/my.cnf
server-id = 1 #一定不能和slave上的server-id相同，必须唯一
log-bin=master-bin.log
sync_binlog=1
innodb_buffer_pool_size = 5600M
innodb_flush_log_at_trx_commit=1
sql_mode=STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION,NO_AUTO_VALUE_ON_ZERO
lower_case_table_names=1
log_bin_trust_function_creators=1
binlog_format = row
slave_parallel_workers=4 #--开启基于库的多线程复制默认0不开启
binlog_cache_size = 8M
max_binlog_size = 50M
max_binlog_cache_size = 100M
expire_logs_days = 1
log-slave-updates=true
rpl_semi_sync_master_enabled=ON
service mysqld start
2、设置主从用户
mysql -uroot -p
grant replication slave on *.* to ‘repl‘@‘192.168.10.2‘ identified by ‘repl‘;
show master status; #记录master上的logfile 和position
四、mysql从设置
1、配置文件
server-id = 2 #一定不能和master上的server-id相同
log-bin = slave-bin.log
sync_binlog = 1
innodb_buffer_pool_size = 512M
innodb_flush_log_at_trx_commit = 1
sql_mode=STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION,NO_AUTO_VALUE_ON_ZERO
lower_case_table_names = 1
log_bin_trust_function_creators = 1
binlog_format = row
binlog_cache_size = 8M
max_binlog_size = 50M
max_binlog_cache_size = 100M
expire_logs_days = 1
slave_parallel_workers=4
max_relay_log_size = 50M
relay_log_purge = 1
relay_log_recovery = 1
master_verify_checksum = 1 #--主事件校验
slave_sql_verify_checksum = 1 #--从事件校验
slave_allow_batching = 1
log-slave-updates=true
service mysqld start
2、开启从库同步线程
mysql -uroot -p
change master to master_ip=‘192.168.10.1‘,master_user=‘repl‘,master_password=‘repl‘,master_log_file=‘slave-bin.000003‘,master_log_pos=5569;
start slave;
show slave status\G;
#Slave_IO_Running: Yes
#Slave_SQL_Running: Yes
上面输出两项均为yes则正常
五、配置mysql 主服务器半同步
1、修改配置文件加入参数
rpl_semi_sync_master_enabled=ON
2、进入mysql命令行安装半同步插件
INSTALL PLUGIN rpl_semi_sync_slave SONAME ‘semisync_master.so‘;
show global viriables like ‘rpl_semi_%‘
+------------------------------------+-------+
| Variable_name | Value |
+------------------------------------+-------+
| rpl_semi_sync_master_enabled | ON |
| rpl_semi_sync_master_timeout | 10000 |
| rpl_semi_sync_master_trace_level | 32 |
| rpl_semi_sync_master_wait_no_slave | ON |
+------------------------------------+-------+
#rpl_semi_sync_master_enabled 为ON则安装成功
重启mysql master
servive mysqld restart
六、配置mysql 从服务器半同步
1、修改配置文件加入参数
rpl_semi_sync_slave_enabled=ON
2、进入mysql命令行安装半同步插件
INSTALL PLUGIN rpl_semi_sync_master SONAME ‘semisync_slave.so‘;
show globle viriables like ‘rpl_semi_%‘
#rpl_semi_sync_slave_enabled 为ON则安装成功
+---------------------------------+-------+
| Variable_name | Value |
+---------------------------------+-------+
| rpl_semi_sync_slave_enabled | ON |
| rpl_semi_sync_slave_trace_level | 32 |
+---------------------------------+-------+
完成。
