CentOS 6.5下二进制安装 MySQL 5.6
CentOS 6.5 二进制安装MySQL 5.6
1：查看系统版本
| 1 2 |
[root@10-4-5-9 mysql]# cat /etc/redhat-release
CentOS release 6.5 (Final)
|
2：下载MySQL5.6二进制包
| 1 |
#wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.20-linux-glibc2.5-i686.tar.gz
|
3：添加用户和组
| 1 2 |
#groupadd mysql
#useradd -g mysql mysql
|
4：安装mysql到/usr/local/mysql下
| 1 2 3 4 5 6 7 |
#cd /usr/local
#tar zxvf /{MySQL5.6_path}/mysql-{version}.tar.gz
例如我的配置路径为：
#cd /usr/local
#tar zxvf /root/mysql-5.6.20-linux-glibc2.5-i686.tar.gz
|
5：修改解压后文件夹名为 mysql
| 1 |
#mv mysql-5.6.20-linux-glibc2.5-i686 mysql
|
6：修改mysql的各级文件夹和文件的创建者、创建组为mysql（注意语句后面有个.）
| 1 2 3 |
cd mysql
chown -R mysql .
chgrp -R mysql .
|
7：至此mysql已经安装完了，但还需要初始化，初始化mysql表、test表、infomation表等。
| 1 |
#scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data<br><br>
|
| 1 |
#cp support-files/mysql.server /etc/init.d/mysqld
|
| 1 2 3 |
--user=mysql
--basedir=/usr/local/mysql
--datadir=/usr/local/mysql/data
|
| 1 2 |
PS：该步骤有可能会报错误
安装需要的包即可:libstdc++.so.6和libaio.so.1和libncurses.so.5
|
8：修改配置文件
| 1 2 3 |
[root@10-4-5-9 mysql]# cp my.cnf /etc/my.cnf
/usr/local/mysql
[root@10-4-5-9 mysql]# vi /etc/my.cnf
|
| 1 2 3 4 5 6 |
[mysqld]中添加：
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
server_id = 1
|
9：启动mySQL服务
| 1 |
#ln -s /usr/local/mysql/bin/mysql /usr/bin
|
10：登陆MySQL并且删除空用户
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
mysql> SELECT user,host,password FROM mysql.user;
+------+-----------+----------+
| user | host | password |
+------+-----------+----------+
| root | localhost | |
| root | 10-4-5-9 | |
| root | 127.0.0.1 | |
| root | ::1 | |
| | localhost | |
| | 10-4-5-9 | |
+------+-----------+----------+
6 rows in set (0.00 sec)
mysql> UPDATE mysql.user set password = PASSWORD('gechong') WHERE user = 'root';
mysql> DROP USER ''@localhost;
mysql> FLUSH PRIVILEGES;
|
