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-1 /]# mkdir  /usr/local/src/mysql-5.7.26-src
[root@server-1]# cd /usr/local/src/mysql-5.7.26-src/
[root@server-1 mysql-5.7.26-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-1 mysql-5.7.26-src]# useradd mysql
[root@server-1 mysql-5.7.26-src]# id mysql
uid=1001(mysql) gid=1001(mysql) 组=1001(mysql)

3、设置mysql用户密码

[root@server-1 mysql-5.7.26-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-1 mysql-5.7.26-src]# mkdir /home/mysql-5.7.26
[root@server-1 mysql-5.7.26-src]# mkdir /home/mysql-5.7.26/data
[root@server-1 mysql-5.7.26-src]# mkdir  /home/mysql-5.7.26/log
[root@server-1 mysql-5.7.26-src]# mkdir -p /home/mysql-5.7.26/run
[root@server-1 home]# chown -R mysql:mysql  mysql-5.7.26/
[root@server-1 home]# cd mysql-5.7.26/
[root@server-1 mysql-5.7.26]# ll
总用量 0
drwxr-xr-x 2 mysql mysql 6 5月  31 14:25 data
drwxr-xr-x 2 mysql mysql 6 5月  31 14:26 log
drwxr-xr-x 2 mysql mysql 6 5月  31 14:26 run

5、安装依赖包

[root@server-1]# 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-1 src]# mv boost_1_59_0 /usr/local/

7、编译安装

[root@server-1 /]# cd /usr/local/src/mysql-5.7.26-src/
[root@server-1 mysql-5.7.26-src]# tar -zxvf mysql-5.7.26.tar.gz 
[root@server-1 mysql-5.7.26]# cd mysql-5.7.26
[root@server-1 mysql-5.7.26]# cmake -DCMAKE_INSTALL_PREFIX=/home/mysql-5.7.26 -DINSTALL_DATADIR=/home/mysql-5.7.26/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DWITH_SSL=yes -DWITH_EMBEDDED_SERVER=1 -DENABLED_LOCAL_INFILE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DMYSQL_UNIX_ADDR=/home/mysql-5.7.26/run/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -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-5.7.26-src/mysql-5.7.26

编译成功,再执行

[root@server-1 mysql-5.7.26]# make && make install

最后出现 

-- Installing: /home/mysql-5.7.26/mysql-test/lib/My/SafeProcess/Base.pm
-- Installing: /home/mysql-5.7.26/support-files/mysqld_multi.server
-- Installing: /home/mysql-5.7.26/support-files/mysql-log-rotate
-- Installing: /home/mysql-5.7.26/support-files/magic
-- Installing: /home/mysql-5.7.26/share/aclocal/mysql.m4
-- Installing: /home/mysql-5.7.26/support-files/mysql.server

8、编写配置文件my.cnf 

[root@server-1 mysql-5.7.26]# vim /etc/my.cnf
[mysqld] bsedir
=/home/mysql-5.7.26 datadir=/home/mysql-5.7.26/data socket=/home/mysql-5.7.26/run/mysql.sock user=mysql symbolic-links=0 [mysqld_safe] log-error=/home/mysql-5.7.26/log/mysqld.log pid-file=/home/mysql-5.7.26/run/mysqld.pid

9、配置环境变量

[root@server-1 mysql-5.7.26]# vim /etc/profile
在文件末尾加上
PATH=$PATH:/home/mysql-5.7.26/bin/
[root@server-1 mysql-5.7.26]# source /etc/profile

10、初始化系统数据库

[root@server-1 /]# mysqld --initialize --user=mysql --basedir=/home/mysql-5.7.26/ --datadir=/home/mysql-5.7.26/data/
[root@server-1 /]# 

没有报错,查看日志中的初始密码

[root@server-1 /]# cat /home/mysql-5.7.26/log/mysqld.log |grep password
2019-06-04T01:56:14.224507Z 1 [Note] A temporary password is generated for root@localhost: dyB8iUq<EaK;

11、启动数据库

[root@server-1 /]# mysqld_safe --defaults-file=/etc/my.cnf --user=mysql &
2019-06-04T02:00:01.566664Z mysqld_safe Logging to /home/mysql-5.7.26/log/mysqld.log.
2019-06-04T02:00:01.629556Z mysqld_safe Starting mysqld daemon with databases from /home/mysql-5.7.26/data

12、启动客户端,输入初始密码登录数据库

[root@server-1 ~]# mysql -uroot -p

13、修改密码

mysql> set PASSWORD=PASSWORD(xxxxxxx);
mysql> alter user root@localhost PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

退出,重新登录

[root@server-1 ~]# 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-5.7.26
datadir=/home/mysql-5.7.26/data
socket=/home/mysql-5.7.26/run/mysql.sock
user=mysql
symbolic-links=0
server_id=69
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-5.7.26/log/mysqld.log
pid-file=/home/mysql-5.7.26/run/mysqld.pid

重启mysql,并登录mysql

[root@server-1 /]# mysqld_safe --defaults-file=/etc/my.cnf --user=mysql &
[1] 29747
[root@server-1 /]# 2019-06-04T02:34:07.501598Z mysqld_safe Logging to /home/mysql-5.7.26/log/mysqld.log.
2019-06-04T02:34:07.554499Z mysqld_safe Starting mysqld daemon with databases from /home/mysql-5.7.26/data
^C
[root@server-1 /]# mysql -uroot -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

mysql> 

查询主库状态

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

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

多了一个Executed_Gtid_Set

查询gitd相关变量

mysql> show variables like %gtid%;
+----------------------------------+-----------+
| Variable_name                    | Value     |
+----------------------------------+-----------+

| session_track_gtids              | OFF       |
+----------------------------------+-----------+
8 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, 0 rows affected, 1 warning (0.02 sec)

3从库配置文件

[mysqld]
basedir=/home/mysql-5.7.26
datadir=/home/mysql-5.7.26/data
socket=/home/mysql-5.7.26/run/mysql.sock
user=mysql
symbolic-links=0
server_id=103
gtid_mode=on #开启gtid模式
enforce_gtid_consistency=on
log-bin=salve
binlog_format=row


[mysqld_safe]
log-error=/home/mysql-5.7.26/log/mysqld.log
pid-file=/home/mysql-5.7.26/run/mysqld.pid

重启mysql

[root@server-2 log]# mysqld_safe --defaults-file=/etc/mysql/my.cnf &
[1] 1037
[root@server-2 log]# 2019-06-04T02:49:07.867996Z mysqld_safe Logging to /home/mysql-5.7.26/log/mysqld.log.
2019-06-04T02:49:07.899183Z mysqld_safe Starting mysqld daemon with databases from /home/mysql-5.7.26/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=1;
Query OK, 0 rows affected, 2 warnings (0.30 sec)

mysql> start slave;
Query OK, 0 rows affected (0.02 sec)

查看从库状态

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

测试

主库新建test库和test表,插入一条记录

mysql> create database test;
Query OK, 1 row affected (0.02 sec)

mysql> use test;
Database changed
mysql> create table test(id int ,name varchar(20));
Query OK, 0 rows affected (0.14 sec)

mysql> insert into test values(1,aaaaa);
Query OK, 1 row affected (0.05 sec)

mysql> select * from test;
+------+-------+
| id   | name  |
+------+-------+
|    1 | aaaaa |
+------+-------+
1 row in set (0.00 sec)

在从库上查看

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
| test               |
+--------------------+
5 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  |
+------+-------+
|    1 | aaaaa |
+------+-------+
1 row in set (0.00 sec)

数据同步成功。
