準備工作

創建用戶

useradd mysql

刪除老版本

rpm -qa |grep mysql
rep -e mysql包

重命名默認的mysql配置文件

mv /etc/my.cnf /etc/my.cnf.old

下載mysql

wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.35.tar.gz

安裝依賴

yum -y install make gcc-c++ cmake bison-devel ncurses-devel

安裝配置

解壓

tar -xf mysql-5.6.35.tar.gz
cd mysql-5.6.35

編譯安裝

cmake \ -DCMAKE_INSTALL_PREFIX=/home/heron/mysql-3306 \ -DMYSQL_DATADIR=/home/heron/mysql/data \ -DMYSQL_UNIX_ADDR=/home/heron/mysql-3306/mysql-3306.sock \ -DSYSCONFDIR=/home/heron/mysql-3306/etc \ -DDEFAULT_CHARSET=utf8 \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_PARTITION_STORAGE_ENGINE=1 \ -DMYSQL_TCP_PORT=3306 \ -DWITH_READLINE=1 \ -DENABLED_LOCAL_INFILE=1 \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_cimake -j8 && make -j8 install

配置啟動

cd /home/heron/mysql-3306/
mkdir logs etc tmp var

初始化

vim /home/heron/mysql-3306/etc/my.cnf

這個配置有關于復制相關的配置，不用復制的話，請忽略，需要從庫只需修改配置server-id并打開read

初始化

/home/heron/mysql-3306/scripts/mysql_install_db

/home/heron/mysql-3307/scripts/mysql_install_db

如果報錯

FATAL ERROR: please install the following Perl modules before executing /home/heron/mysql-3306/scripts/mysql_install_db:

安裝下面的包

yum install -y perl-Module-Install.noarch

啟動

/home/heron/mysql-3306/bin/mysqld_safe &
/home/heron/mysql-3307/bin/mysqld_safe &

建議使用supervisor管理

[program:mysql-3306] command= /home/heron/mysql-3306/bin/mysqld --defaults-file=/home/heron/mysql-3306/etc/my.cnf directory=/home/heron/mysql-3306 user=heron[program:mysql-3307] command= /home/heron/mysql-3307/bin/mysqld --defaults-file=/home/heron/mysql-3307/etc/my.cnf directory=/home/heron/mysql-3307 user=heron

默認沒有密碼 設置root密碼

SET PASSWORD = PASSWORD('123456');

安裝告一段落

主從同步

創建同步賬號

登錄主庫

GRANT RELOAD, REPLICATION SLAVE, SUPER ON . TO 'slave'@'127.0.0.1' IDENTIFIED BY '123456';

flush privileges;

查看主庫狀態

root@localhost 19:25: [(none)]> show master status;
+------------------+----------+--------------+------------------+------------------------------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |

+------------------+----------+--------------+------------------+------------------------------------------+

登錄從庫

CHANGE MASTER TO MASTER_HOST='127.0.0.1', MASTER_USER='slave', MASTER_PASSWORD='123456', MASTER_PORT=3306, MASTER_LOG_FILE='mysql-bin.000004', MASTER_LOG_POS=1638, MASTER_CONNECT_RETRY=5, MASTER_HEARTBEAT_PERIOD=3;

開啟slave

start slave

查看slave

Slave_IO_Running: Yes
Slave_SQL_Running: Yes

有這兩項就說明成功了。

至此 MySQL5.6的安裝、配置、啟動、主從就完成了。
