 2.1 配置 mysql

# 软连接
[root@db2 mysql-5.6.36]# ln -s /data/mysql-5.6.36/ /data/mysql

# 拷贝配置文件到/etc下   
[root@db2 mysql-5.6.36]# cp support-files/my*.cnf  /etc/my.cnf 
cp: overwrite `/etc/my.cnf'? y

# 初始化数据库
[root@db2 mysql-5.6.36]# /data/mysql/scripts/mysql_install_db --basedir=/data/mysql/ --datadir=/data/mysql/data --user=mysql



# 创建关键目录并设置权限
[root@db2 mysql-5.6.36]# mkdir -p /data/mysql/tmp
[root@db2 mysql-5.6.36]# chown -R mysql.mysql  /data/mysql/

# 复制 启动文件
[root@db2 mysql-5.6.36]# cp support-files/mysql.server  /etc/init.d/mysqld

# 启动mysql
[root@db2 mysql-5.6.36]# chmod +x /etc/init.d/mysqld
 
#配置环境变量

basedir=/data/mysql
socket=/data/mysql/tmp/mysql.sock
port=3306
server_id=10
log-error=/var/log/mysql.log
log-bin=/data/mysql/data/mysql-bin
binlog_format=row
skip_name_resolve

[mysql]

4 mysql启动和关闭

4.1 启动mysql

数据库的启动流程

mysql.server ------>mysqld_safe------->mysqld

 

启动：
[root@db02 ~]# /etc/init.d/mysqld start
或者：
[root@db02 ~]# /data/mysql/bin/mysqld_safe &

 

关闭：
[root@db02 ~]# mysqladmin -uroot -p123456 shutdown
或者：
[root@db02 ~]# /etc/init.d/mysqld stop

5 设置密码

 

① mysql root 密码为空时的设置

/data/mysql-5.6.36/bin/mysqladmin -uroot password "123456"
/data/mysql-5.6.36/bin/mysql  -uroot -p123456

mysqladmin  -u root -p112233  password '123456';
mysqladmin     -uroot -pold_pwd   password "new_pwd"

②   登录mysql再设置 

mysql> use mysql
Database changed
mysql> set password for root@localhost=password("123123");
Query OK, 0 rows affected (0.00 sec)

③ 登录mysql再设置

mysql> use mysql
Database changed
mysql> update user set password=password("123456") where user='root' and host='localhost';
Query OK, 1 row affected (0.00 sec)

6 设置mysql 开机启动

[root@db2 tmp]# chkconfig --add mysqld
[root@db2 tmp]# chkconfig | grep mysql 
mysqld             0:off    1:off    2:on    3:on    4:on    5:on    6:off

7 配置环境变量

echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile 

source /etc/profile

1. 简述mysql数据库支持的安装方式：

　　yum安装    源码安装   二进制安装

2 简述mysql_install_db命令的查用参数：

　  mysql_install_db  是初始化的命令

　　mysql_install_db  --basedir=/data/mysql/   --datadir=/data/mysql/data   --user=mysql

　　　　　　　　　　 basedir 安装路径　　　　datadir 数据库的存放路径
