## 创建相关目录，授权

```
chmod +w /opt/local/mysql

chown -R mysql:mysql /opt/local/mysql

chmod +w /var/lib/mysql

chown -R mysql:mysql /var/lib/mysql

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

chmod 755 /etc/init.d/mysqld

echo 'basedir=/opt/local/mysql/' >> /etc/init.d/mysqld

echo 'datadir=/opt/local/mysql/data' >>/etc/init.d/mysqld
```
 

 
## 创建相关链接

```
ln -s /opt/local/mysql/lib/mysql /usr/lib/mysql

ln -s /opt/local/mysql/include/mysql /usr/include/mysql

ln -s /opt/local/mysql/bin/mysql /usr/bin/mysql

ln -s /opt/local/mysql/bin/mysqldump /usr/bin/mysqldump

ln -s /opt/local/mysql/bin/myisamchk /usr/bin/myisamchk

ln -s /opt/local/mysql/bin/mysqld_safe /usr/bin/mysqld_safe

ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock
```
 
## 初始化数据库

```
rm -rf /etc/my.cnf

cp /opt/local/mysql/support-files/my-default.cnf /opt/local/mysql/etc/my.cnf

cd /opt/local/mysql/bin/

./mysqld --initialize --user=mysql --basedir=/opt/local/mysql --datadir=/opt/local/mysql/data
```
 

初始化完毕会生成一个root 的 随机密码，请务必先记录一下。如果忘记了，请查看 (mysqld.log)

```
service mysqld start
```

```
/opt/local/mysql/bin/mysql_secure_installation -uroot -p
