安装cmake

[root@localhost tools]# tar -xf cmake-2.8.8.tar.gz

[root@localhost tools]# cd cmake-2.8.8/

[root@localhost cmake-2.8.8]# gmake install

[root@localhost ~]# cd tools/

[root@localhost tools]# tar -xf mysql-5.5.32.tar.gz

[root@localhost tools]# cd mysql-5.5.32/

[root@localhost mysql-5.5.32]# cat install-mysql5.5.32.sh

[root@localhost mysql-5.5.32]# bash install-mysql5.5.32.sh

[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

Filling help 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

Password updated successfully!

……

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)
