mysql5.7部署、初始化和创建实例

标签：mysql初始化 创建实例 5.7

环境信息：
centos 7.2
mysql 5.7.21

1.下载解压缩mysql包

cd /usr/local/
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz
tar xzvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz
mv mysql-5.7.21-linux-glibc2.12-x86_64 mysql

2.初始化mysql基础环境信息

vim /etc/profile
PATH=/home/mysql/bin:/home/mysql/lib:$PATH
export PATH
export MYSQL_HOME="/usr/local/mysql"
export ms="/usr/local/mysql"

3.初始化配置实例配置文件

mkdir -p /usr/local/mysql/data/mcdb
vi /usr/local/mysql/data/mcdb/my.cnf

[client]
port = 3310
socket = /usr/local/mysql/data/mcdb/mysql.sock
[mysql]
no-auto-rehash
[mysqld]
user = mysql
port = 3310
socket = /usr/local/mysql/data/mcdb/mysql.sock
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
pid-file = /usr/local/mysql/data/mcdb/mysql.pid
relay-log = /usr/local/mysql/data/mcdb/relay-bin
relay-log-info-file = /usr/local/mysql/data/mcdb/relay-log.info
server-id = 12
[mysqld_safe]
log-error = /usr/local/mysql/data/mcdb/mysql.err
pid-file = /usr/local/mysql/data/mcdb/mysql.pid

4.新建用户

groupadd mysql
useradd mysql -g mysql
chown mysql:mysql /usr/loca/mysql -R

5.初始化mysql实例
mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/mcdb --user=mysql --ldata=/usr/local/mysql
从返回信息最后一行获得密码，举个栗子：
yUlta1lw*uwF

6.启动该实例mysql
mysqld_safe --defaults-file=/usr/local/mysql/data/mcdb/my.cnf --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/mcdb &

7.登录mysql
mysql -uroot -pyUlta1lw*uwF -S /usr/local/mysql/data/mcdb/mysql.sock

8.设定密码

mysql> SET PASSWORD = PASSWORD(‘sonyw320‘); 
mysql> flush privileges;

9.创建用户并开放远程登录权限
grant all privileges on *.* to ‘bodie‘@‘%‘ identified by ‘happybirthday‘ with grant option;
