今天安装的是二进制的mysql包5.7.21的包,在配置文件的时候采了好多坑,左后还是搞定了,来和大家分享一下
二进制msyql5.7.21版本的主从复制安装
新建/picclife目录
mkdir /picclife
新建/picclife/data 目录
mkdir /picclife/data
创建用户和组 为mysql
groupadd mysql
useradd -g mysql mysql
将二进制mysql的包传到/picclife的目录下
解压软件包
tar -zxf 二进制包
改名
mv 解压出来的包 mysql
加属组属主
chown -R mysql:mysql mysql
配置环境变量
vim /etc/profile
mysql_home=/picclife/mysql
export PATH=$PATH:$mysql_home/bin
生效
source /etc/profile
编辑配置文件
vim /etc/my.cnf

安装数据库
./bin/mysqld --initialize --user=mysql --basedir=/picclfie/mysql --datadir=/picclife/data --innodb_undo_tablespaces=3 --explicit_defaults_for_timestamp
创建启动文件
cp /picclife/mysql/support-files/mysql.server /etc/init.d/mysqld
修改/etc/init.d/mysql
加入到开机启动项
chkconfig --add mysqld
设置开机启动
chkconfig mysqld on
开启mysql
service mysqld start
启动也可以
(
数据库常规启停
mysqladmin -uroot -proot shutdown
mysqld_safe --defaults-file=/etc/my.cnf &
ps -ef|grep mysql
)
查看默认密码
grep -i password /picclife/data/mysql-error.log
用初始化密码登陆数据库修改密码
mysql -uroot -p查到的密码
修改密码
SET PASSWORD=PASSWORD(‘密码‘);
flush privileges;
然后推出可以用新改的密码登陆了
主的配置文件 已经修改好了,进入数据库授权
给从服务器slave复制的权限:
grant replication slave on *.* to [email protected]”从的ip” identified by “123”;
刷新权限:
glush privileges;
查看主服务器master的状态已得到二进制的名和位置:
show master status;
主就配置好了开始配置从:
从的二进制安装mysql和住的一样
就是配置文件里的server id 不能冲突 可以开启二进制日志也可以不开启,但必须开启中继日志relay_log = mysql-relay

其余的按爪功你安装和主的一样
进入数据库
进入数据库:
关闭slave:
stop slave;
设置master的host user 二进制的名字位置等:
change master to master_host=”主的ip”,master_user=”tom”,mster_password=”123”,
master_log_file=”mysql-bin.000002”,master_log_pos=106;
开启slave
start slave;
查看slave的状态:
现在主从复制完成,可以在主上创建库。从上查看
注意:如果以上配置文件启动报错,就使用最下面的配置
