mysql安装步骤-包括主从

安装mysql

yum install cmake -y          否则装mysql时候报错：-bash: cmake: command not found

groupadd  mysql

useradd -r -g mysql mysql

tar zxvf cmake-3.0.0.tar.gz

cd cmake-3.0.0

./bootstrap

gmake  &  gmake install 

报错：make clean  再次  gmake & make install

gmake[2]: *** [bin/cmake] Error 1

gmake[1]: *** [Source/CMakeFiles/cmake.dir/all] Error 2)

tar zxvf mysql-5.6.19.tar.gz

cd  mysql-5.6.19

复制启动脚本:

cd /home/mysql

cp ./support-files/mysql.server /etc/init.d/mysqld

vi /etc/init.d/mysqld

修改:

basedir=

datadir=

为

basedir=/home/mysql

basedir=/home/mysql

datadir=/home/mysql/data

chmod 755 /etc/init.d/mysqld

chkconfig --add mysqld

chkconfig --level 345 mysqld on

chkconfig --list mysqld

初始化数据库:

之前：vim /etc/hosts  加上 127.0.0.1 hostsname

cd /home/mysql

chown -R mysql:mysql /home/mysql

cd /home/mysql/mysql-5.6.19

make

make install

chown -R mysql:mysql /home/mysql

./scripts/mysql_install_db --user=mysql --base=/home/mysql/ --datadir=/home/mysql/data/  --explicit_defaults_for_timestamp

提示 Installing MySQL system tables...OK

（如果报错，请试试添加如下环境变量试试，如不报错，接下来才去配置环境变量）

sql加入到环境变量

vi /etc/profile

#mysql

export PATH=$PATH:$HOME/bin:/home/mysql/bin:/home/mysql/lib

source /etc/profile

/etc/init.d/mysqld restart

添加权限

mysql -uroot -p   

=========================================

（

默认空密码回车

报错

[mysql@jsjxapp ~]$ mysql -uroot -p

Enter password:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/home/mysql/mysqld.sock' (2)

看一下/etc/my.cnf

我是留下 socket  = /home/mysql/mysqld.sock

发现只有/tmp/mysqld.sock  而/home/mysql下面没做有，找不到mysql.sock，英明的我果断做了个软连接

ln -s /tmp/mysqld.sock /home/mysql/mysqld.sock

再次

mysql -uroot -p 空密码回车，解决问题

）

==========================================

use mysql;

delete from user where not (user='root') ;

delete from user where user='root' and password='';

grant all on *.* to root@'localhost'  identified by 'rootdb!xxx' with grant option ;

grant all on *.* to jsjx@'%'  identified by 'jsjxdb';

grant all on *.* to select_v@'%'  identified by 'mysql_select';

select host,user,password from mysql.user;

flush privileges;

动主库生效，并赋予从库权限帐号，允许用户在主库上读取日志

GRANT REPLICATION SLAVE ON *.* TO 'slave'@'%' IDENTIFIED BY 'slave.123#!';

flush privileges;

select host,user,password from mysql.user;

主:

flush tables with read lock;

show master status;

unlock tables;

从:

stop slave;

change master to master_host='192.168.2.100',master_user='slave',master_password='slave.123#!',master_port=3306,master_log_file='mysql-bin.000007',master_log_pos=4;

start slave;

show slave status\G;

如果Slave_IO_Running、Slave_SQL_Running状态为Yes则表明设置成功。

从库的my.cnf添加

server-id      = 2
