新版mysql搭建多线程主从复制

一:首先得到
mysql-5.7.11-1.el6.x86_64.rpm-bundle.tar

tar xf mysql-5.7.11-1.el6.x86_64.rpm-bundle.tar
yum install -y mysql-community-client-5.7.11-1.el6.x86_64.rpm
mysql-community-common-5.7.11-1.el6.x86_64.rpm
mysql-community-libs-5.7.11- 1.el6.x86_64.rpm
mysql-community-libs-compat-5.7.11-1.el6.x86_64.rpm
mysql-community-server-5.7.11-1.el6.x86_64.rpm

启动:
/etc/init.d/mysqld start
[[email protected]
mnt]# /etc/init.d/mysqld start
Initializing MySQL database: [ OK ]
Installing validate password plugin: [ OK ]
Starting mysqld: [ OK ]

获得初始密码:
grep ‘temporary password’ /var/log/mysqld.log
mysql -p 回车之后输入初始密码

改密码:
ALTER USER
[email protected]
identified by ‘Redhat007!’
密码规则:必须大于八位 ,有大写,小写,数字,特殊字符

然后在里面创建数据库 xp1 后面测试要用
mysql> create database xp1;
然后我在 /mnt底下创建了add.sql (方便后面使用)代码如下:

CREATE TABLE usertb (
 id serial,
uname varchar(20),
ucreatetime datetime ,
age int(11)
)
ENGINE=MYISAM
DEFAULT CHARACTER SET=utf8 COLLATE=utf8_general_ci
AUTO_INCREMENT=1
ROW_FORMAT=COMPACT;

delimiter $$
SET AUTOCOMMIT = 0$$

create procedure test1()
begin
declare v_cnt decimal (10) default 0 ;
dd:loop
insert into usertb values
(null,'用户1','2010-01-01 00:00:00',20),
(null,'用户2','2010-01-01 00:00:00',20),
(null,'用户3','2010-01-01 00:00:00',20),
(null,'用户4','2010-01-01 00:00:00',20),
(null,'用户5','2011-01-01 00:00:00',20),
(null,'用户6','2011-01-01 00:00:00',20),
(null,'用户7','2011-01-01 00:00:00',20),
(null,'用户8','2012-01-01 00:00:00',20),
(null,'用户9','2012-01-01 00:00:00',20),
(null,'用户0','2012-01-01 00:00:00',20)
;
commit;
set v_cnt = v_cnt+10 ;
if v_cnt = 10000000 then leave dd;
end if;
end loop dd ;
end;$$

delimiter ; 

然后在新创建的那个数据库中执行那段代码
图片 1
触发代码中的存储过程
call test1 会在usertb 表中插入一千万行数据
如下证明数据已经插入
图片 2
修改代码,在向其中创建表usertb1 ,然后继续触发,往里面写入一千万行数据
(创建两个表主要想让mysqldump和mysqlpump的差别更明显)
如下证明创建成功
图片 3

测试mysqldump 和mysqlpump
mysqldump:
图片 4
mysqlpump:
time mysqlpump -p xp1 > xp1.sql
图片 5
如上,明显快了十秒,这还使用的是mysqlpump的默认线程数 2
time mysqlpump -pRedhat006! –default-parallelism=4 db1 > db1.sql
–default-parallelism=4 使用线程数 可以自己修改

做个mysql的A — B复制
配置环境: master: 172.25.254.10
slave: 172.25.254.11
首先在master主机里
vim /etc/my.cnf
server-id=1
log-bin=mysql-bin
binlog-do-db=test
/etc/init.d/mysqld restart
mysql -pRedhat007!
用如下命令查看一下,看是否成功
图片 6
新建test库: create database test;

授权:
mysql> grant replication slave on *.* to
[email protected]’172.25.254.11′
identified by ‘Redhat007!’;
Query OK, 0 rows affected, 1 warning (0.40 sec)
/etc/init.d/mysqld restart

slave端: 172.25.254.11
vim /etc/my.cnf
server-id=2 与master不同即可
然后再slave上面安装最新版的mysql
首先验证master是否授权成功
mysql -pRedhat007! -uxpp -h172.25.254.10
如果可以登录进去的话就证明成功

mysql -pRedhat007!
新建test库,因为在做同步之前两个数据库中的内容必须一致
然后:chang master to master_host=’172.25.254.10′, master_user=’xpp’ ,
master_password=’Redhat007!’, master_log_file=’mysql-bin.000001′,
master_log_pos=154;

/etc/init.d/mysqld restart

在master端:
MySQL 的新特性之一,是加入了全局事务 ID (GTID)
来强化数据库的主备一致性,故障恢复,以及容错能力
vim /etc/my.cnf 加如下两行,开启gtid模式

gtid-mode=on
enforce-gtid-consistency=on

/etc/init.d/mysqld restart

然后再slave上
vim /etc/my.cnf 加如下
gtid-mode=on
enforce-gtid-consistency=on
slave-parallel-type=LOGICAL_CLOCK
slave-parallel-workers=16
master_info_repository=TABLE
relay_log_info_repository=TABLE
relay_log_recovery=ON

/etc/init.d/mysqld restart

一:首先得到
mysql-5.7.11-1.el6.x86_64.rpm-bundle.tar tar xf
mysql-5.7.11-1.el6.x86_64.rpm-bundle.tar yum install -y
mysql-community-cl…

我这里是RHEL6.5的系统,因此选择RedHat 6
x86,64bit操作系统—下载第一个RPM
Bundle即可–mysql-8.0.11-1.el6.x86_64.rpm-bundle.tar。

目前MySQL8.0.11社区版提供了多种多样的安装方式,但是并未发现针对Linux
Generic安装包包含的mysql_secure_installation的安装说明。

目前MySQL8.0.11社区版提供了多种多样的安装方式,你也可以通过下载Linux
Generic安装包mysql-8.0.11-linux-glibc2.12-x86_64.tar.gz来安装,这种安装方式无需考虑包兼容性,本文只描述rpm安装方式。

因此这里使用推荐的RPM安装:

一、mysql-8.0.11-1.el6.x86_64.rpm-bundle.tar解压后有如下7个文件:

一、mysql-8.0.11-1.el6.x86_64.rpm-bundle.tar解压后有如下7个文件:

然后创建mysql用户:

然后创建mysql用户:

useradd mysql
passwd mysql
useradd mysqlpasswd mysql

二、安装顺序为:(建议装之前先把之前的mysql相关包全部卸载,rpm
-e –nodeps <包名>即可)

二、安装顺序为:

四、发现没密码不能登录,于是添加skip-grant-tables到my.cnf,重启进去重置密码

Ps:20180517新添加:在安装完后,/var/log/mysqld.log里应该含有临时的root密码,可以直接登录,但是依然建议按本文方法修改掉密码认证的策略。
而在Windows平台使用msi安装时,则有自主选择密码认证方式的步骤,可以比较方便的进行设置。
