mysql5.7使用gtid模式搭建主从复制架构

一、架构

两台mysql服务器做一主一从，172.28.18.69（主） 172.28.18.78（从）

二、分别编译安装mysql5.7

1、下载mysql5.7.26源码包

[root@server- /]# mkdir  /usr/local/src/mysql-5.7.-src
[root@server-]# cd /usr/local/src/mysql-5.7.-src/
[root@server- mysql-5.7.-src]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.26.tar.gz

2、添加mysql用户和组

[root@server- mysql-5.7.-src]# useradd mysql
[root@server- mysql-5.7.-src]# id mysql
uid=(mysql) gid=(mysql) 组=(mysql)

3、设置mysql用户密码

[root@server- mysql-5.7.-src]# passwd mysql
更改用户 mysql 的密码 。
新的 密码：
重新输入新的 密码：
passwd：所有的身份验证令牌已经成功更新。

4、新建mysql相关目录，并赋权限给mysql用户

[root@server- mysql-5.7.-src]# mkdir /home/mysql-5.7.
[root@server- mysql-5.7.-src]# mkdir /home/mysql-5.7./data
[root@server- mysql-5.7.-src]# mkdir  /home/mysql-5.7./log
[root@server- mysql-5.7.-src]# mkdir -p /home/mysql-5.7./run
[root@server- home]# chown -R mysql:mysql  mysql-5.7./
[root@server- home]# cd mysql-5.7./
[root@server- mysql-5.7.]# ll
总用量
drwxr-xr-x  mysql mysql  5月   : data
drwxr-xr-x  mysql mysql  5月   : log
drwxr-xr-x  mysql mysql  5月   : run

5、安装依赖包

[root@server-]# yum install cmake gcc gcc-c++ ncurses-devel bison zlib libxml openssl automake autoconf make libtool bison-devel libaio-devel -y

6、安装boost

MySQL5.7.24要求boost的版本是1.59，更高版本的不适用MySQL5.7.24

[root@server-1 /]# cd /usr/local/src/
[root@server-1 src]# wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz
[root@server-1 src]# tar -zxvf  boost_1_59_0.tar.gz
[root@server- src]# mv boost_1_59_0 /usr/local/

7、编译安装

[root@server- /]# cd /usr/local/src/mysql-5.7.-src/
[root@server- mysql-5.7.-src]# tar -zxvf mysql-5.7..tar.gz
[root@server- mysql-5.7.]# cd mysql-5.7.

[root@server- mysql-5.7.]# cmake -DCMAKE_INSTALL_PREFIX=/home/mysql-5.7. -DINSTALL_DATADIR=/home/mysql-5.7./data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DWITH_SSL=yes -DWITH_EMBEDDED_SERVER= -DENABLED_LOCAL_INFILE= -DWITH_MYISAM_STORAGE_ENGINE= -DWITH_INNOBASE_STORAGE_ENGINE= -DWITH_ARCHIVE_STORAGE_ENGINE= -DWITH_BLACKHOLE_STORAGE_ENGINE= -DWITH_FEDERATED_STORAGE_ENGINE= -DWITH_PARTITION_STORAGE_ENGINE= -DMYSQL_UNIX_ADDR=/home/mysql-5.7./run/mysql.sock -DMYSQL_TCP_PORT= -DENABLED_LOCAL_INFILE= -DSYSCONFDIR=/etc -DWITH_READLINE=on -DWITH_BOOST=/usr/local/boost_1_59_0

如果中途出现错误，则根据错误信息去查找问题，再次编译的时候，一定需要删除mysql-5.7.26下的CMakeCache.txt这个文件，清空缓存才能再次编译，否则还是跟上次一样出现错误。

最后出现

CMake Warning:
  Manually-specified variables were not used by the project:

    INSTALL_DATADIR
    WITH_READLINE

-- Build files have been written to: /usr/local/src/mysql-5.7.-src/mysql-5.7.

编译成功，再执行

[root@server- mysql-5.7.]# make && make install

最后出现

-- Installing: /home/mysql-5.7./mysql-test/lib/My/SafeProcess/Base.pm
-- Installing: /home/mysql-5.7./support-files/mysqld_multi.server
-- Installing: /home/mysql-5.7./support-files/mysql-log-rotate
-- Installing: /home/mysql-5.7./support-files/magic
-- Installing: /home/mysql-5.7./share/aclocal/mysql.m4
-- Installing: /home/mysql-5.7./support-files/mysql.server

8、编写配置文件my.cnf

[root@server- mysql-5.7.]# vim /etc/my.cnf
[mysqld]
bsedir=/home/mysql-5.7.
datadir=/home/mysql-5.7./data
socket=/home/mysql-5.7./run/mysql.sock
user=mysql
symbolic-links=
[mysqld_safe]
log-error=/home/mysql-5.7./log/mysqld.log
pid-file=/home/mysql-5.7./run/mysqld.pid

9、配置环境变量

[root@server- mysql-5.7.]# vim /etc/profile
在文件末尾加上
PATH=$PATH:/home/mysql-5.7./bin/
[root@server- mysql-5.7.]# source /etc/profile

10、初始化系统数据库

[root@server- /]# mysqld --initialize --user=mysql --basedir=/home/mysql-5.7./ --datadir=/home/mysql-5.7./data/
[root@server- /]# 

没有报错，查看日志中的初始密码

[root@server- /]# cat /home/mysql-5.7./log/mysqld.log |grep password
--04T01::.224507Z  [Note] A temporary password is generated for root@localhost: dyB8iUq<EaK;

11、启动数据库

[root@server- /]# mysqld_safe --defaults-file=/etc/my.cnf --user=mysql &
--04T02::.566664Z mysqld_safe Logging to '/home/mysql-5.7.26/log/mysqld.log'.
--04T02::.629556Z mysqld_safe Starting mysqld daemon with databases from /home/mysql-5.7./data

12、启动客户端,输入初始密码登录数据库

[root@server- ~]# mysql -uroot -p

13、修改密码

mysql> set PASSWORD=PASSWORD('xxxxxxx');
mysql> alter user 'root'@'localhost' PASSWORD EXPIRE NEVER;
Query OK,  rows affected (0.00 sec)

mysql> flush privileges;
Query OK,  rows affected (0.00 sec)

退出，重新登录

[root@server- ~]# mysql -uroot -p
Enter password:

mysql> 

三、配置主从配置

1、主库172.28.18.69配置文件

[mysqld]
basedir=/home/mysql-5.7.
datadir=/home/mysql-5.7./data
socket=/home/mysql-5.7./run/mysql.sock
user=mysql
symbolic-links=
server_id=
gtid_mode=on #开启gtid模式
enforce_gtid_consistency=on #强制gtid一致性
log-bin=master #开启二进制日志
binlog_format=row

[mysqld_safe]
log-error=/home/mysql-5.7./log/mysqld.log
pid-file=/home/mysql-5.7./run/mysqld.pid

重启mysql，并登录mysql

[root@server- /]# mysqld_safe --defaults-file=/etc/my.cnf --user=mysql &
[]
[root@server- /]# --04T02::.501598Z mysqld_safe Logging to '/home/mysql-5.7.26/log/mysqld.log'.
--04T02::.554499Z mysqld_safe Starting mysqld daemon with databases from /home/mysql-5.7./data
^C
[root@server- /]# mysql -uroot -p
Enter password:

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> 

查询主库状态

mysql> show master status;
+---------------+----------+--------------+------------------+-------------------+
| File          | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+---------------+----------+--------------+------------------+-------------------+
| master. |       |              |                  |                   |
+---------------+----------+--------------+------------------+-------------------+

多了一个Executed_Gtid_Set

查询gitd相关变量

mysql> show variables like '%gtid%';
+----------------------------------+-----------+
| Variable_name                    | Value     |
+----------------------------------+-----------+
| binlog_gtid_simple_recovery      | ON        |
| enforce_gtid_consistency         | ON        |
| gtid_executed_compression_period |       |
| gtid_mode                        | ON        |
| gtid_next                        | AUTOMATIC |
| gtid_owned                       |           |
| gtid_purged                      |           |
| session_track_gtids              | OFF       |
+----------------------------------+-----------+
 rows in set (0.00 sec)

2、主库上创建repl账号

mysql> grant replication slave,replication client on *.* to 'repl'@'%' identified by 'xxxxxx';
Query OK,  rows affected,  warning (0.02 sec)

3从库配置文件

[mysqld]
basedir=/home/mysql-5.7.
datadir=/home/mysql-5.7./data
socket=/home/mysql-5.7./run/mysql.sock
user=mysql
symbolic-links=
server_id=
gtid_mode=on #开启gtid模式
enforce_gtid_consistency=on
log-bin=salve
binlog_format=row

[mysqld_safe]
log-error=/home/mysql-5.7./log/mysqld.log
pid-file=/home/mysql-5.7./run/mysqld.pid

重启mysql

[root@server- log]# mysqld_safe --defaults-file=/etc/mysql/my.cnf &
[]
[root@server- log]# --04T02::.867996Z mysqld_safe Logging to '/home/mysql-5.7.26/log/mysqld.log'.
--04T02::.899183Z mysqld_safe Starting mysqld daemon with databases from /home/mysql-5.7./data

登录mysql，从库执行以下命令

mysql> change master to master_host='172.28.18.69' ,master_user='repl',master_password='xxxxxx',master_auto_position=;
Query OK,  rows affected,  warnings (0.30 sec)

mysql> start slave;
Query OK,  rows affected (0.02 sec)

查看从库状态

mysql> show slave status\G;

测试

主库新建test库和test表，插入一条记录

mysql> create database test;
Query OK,  row affected (0.02 sec)

mysql> use test;
Database changed
mysql> create table test(id int ,name varchar());
Query OK,  rows affected (0.14 sec)

mysql> insert into test values(,'aaaaa');
Query OK,  row affected (0.05 sec)

mysql> select * from test;
+------+-------+
| id   | name  |
+------+-------+
|     | aaaaa |
+------+-------+
 row in set (0.00 sec)

在从库上查看

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
| test               |
+--------------------+
 rows in set (0.00 sec)

mysql> use test;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> select * from test;
+------+-------+
| id   | name  |
+------+-------+
|     | aaaaa |
+------+-------+
 row in set (0.00 sec)

数据同步成功。
