[root@localhost mysql-5.5.32]# make -j 4 && make install
初始化配置
[root@localhost ~]# useradd -M -s /sbin/nologin mysql
[root@localhost ~]# cd tools/mysql-5.5.32/
[root@localhost mysql-5.5.32]# cp support-files/my-medium.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y
添加启动脚本到系统中
[root@localhost mysql-5.5.32]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
[root@localhost mysql-5.5.32]# chmod 750 /etc/rc.d/init.d/mysqld
环境变量配置
[root@localhost ~]# source /etc/profile
[root@localhost ~]# tail -n 1 /etc/profile
PATH=/usr/local/mysql/bin/:$PATH
初始化数据库
[root@localhost ~]# chown -R mysql.mysql /usr/local/mysql
[root@localhost ~]# cd /usr/local/mysql/scripts/
[root@localhost scripts]# ./mysql_install_db \
\> --basedir=/usr/local/mysql \
\> --datadir=/usr/local/mysql/data \
\> --user=mysql
Installing MySQL system tables...
OK

启动服务
[root@localhost ~]# service mysqld start
Starting MySQL... SUCCESS!
[root@localhost ~]# netstat -anutp | grep mysqld
tcp 0 0 0.0.0.0:3306 0.0.0.0: LISTEN 28170/mysqld
设置密码(这里使用自带的安全脚本)
[root@localhost ~]# mysql_secure_installation
……
Set root password? [Y/n]
New password: 1
Re-enter new password: 1

查看授权表
[root@localhost ~]# mysql -uroot -p1
mysql> select user,host from mysql.user;
+------+-----------+
| user | host |
+------+-----------+
| root | 127.0.0.1 |
| root | ::1 |
| root | localhost |
+------+-----------+
3 rows in set (0.01 sec)
删除多余的授权数据项
mysql> delete from mysql.user where host='::1';
Query OK, 1 row affected (0.00 sec)
mysql> select user,host from mysql.user;
+------+-----------+
| user | host |
+------+-----------+
| root | 127.0.0.1 |
| root | localhost |
+------+-----------+
2 rows in set (0.00 sec)
或者全部删除，添加额外管理员
mysql> delete from mysql.user;
Query OK, 2 rows affected (0.00 sec)
mysql> grant all privileges on .* to system@'localhost' identified by '123' with grant option;
Query OK, 0 rows affected (0.01 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
with grant option 此参数可以指定此用户可以授权别人权限
mysql> select user,host from mysql.user;
+--------+-----------+
| user | host |
+--------+-----------+
| system | localhost |
+--------+-----------+
1 row in set (0.00 sec)
