CentOS6.6下解压安装mysql-5.7.10-linux-glibc2.5-i686.tar.gz

2341

mysql-5.7.10-linux-glibc2.5-i686.tar.gz是目前最新版，二进制发布包，适合各种32为版本的发型版Linux，由于只有一个包，解压后配配就行，很方便，比较符合我的风格。

环境：centos6.6 x86

1、下载 http://dev.mysql.com/downloads/mysql/
http://dev.mysql.com/get/Downloa ... libc2.5-i686.tar.gz
迅雷下载后ftp传到Linux下面/usr/local/soft/


2、解压缩到/usr/local/下面，mysql的主目录命名为mysql
[iyunv@localhost local]# cd /usr/local/soft/
[iyunv@localhost soft]# tar zvxf mysql-5.7.10-linux-glibc2.5-i686.tar.gz -C /usr/local
[iyunv@localhost soft]# cd ..
[iyunv@localhost local]# mv mysql-5.7.10-linux-glibc2.5-i686/ mysql


3、在mysql下面创建data数据库文件目录
[iyunv@localhost local]# mkdir mysql/data

4、创建mysql的用户组和用户，并对mysql目录设置用户组和用户
[iyunv@localhost local]# groupadd mysql
[iyunv@localhost local]# useradd mysql -g mysql
[iyunv@localhost local]# cd mysql
[iyunv@localhost mysql]# pwd
/usr/local/mysql
[iyunv@localhost mysql]# chown -R mysql .
[iyunv@localhost mysql]# chgrp -R mysql .

5、初始化mysql并启动mysql服务
[iyunv@localhost mysql]# cd /usr/local/mysql/bin
[iyunv@localhost bin]# yum install libaio
./mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data已加载插件：fastestmirror, refresh-packagekit, security
设置安装进程
Loading mirror speeds from cached hostfile
* base: mirrors.opencas.cn
* extras: mirrors.btte.net
* updates: mirrors.btte.net
包 libaio-0.3.107-10.el6.i686 已安装并且是最新版本
无须任何处理
[iyunv@localhost bin]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data

2016-01-09T04:00:29.264643Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000)
2016-01-09T04:00:29.264653Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)

[iyunv@localhost bin]# cd /usr/local/mysql/support-files
[iyunv@localhost support-files]# ./mysql.server start
Starting MySQL. SUCCESS!

6、登录mysql，此版本最新版不许空密码登录，实际上有个初始化密码保存在/root/.mysql_secret这个文件里面，用这个密码第一次登录后，再修改密码。因此先cat查看下初始化密码（随机的，每次安装看到的密码都不一样）：
[iyunv@localhost ~]# cat /root/.mysql_secret
# Password set for user 'root@localhost' at 2016-01-09 12:00:28
:5ul#H6dmcwX

利用初始化密码:5ul#H6dmcwX开始登录mysql：
[iyunv@localhost ~]# cd /usr/local/mysql/bin
[iyunv@localhost bin]# ./mysql -uroot -p:5ul#H6dmcwX
mysql: [Warning] Using a password on the command line interface can be insecure.

mysql>

显示登录成功，可以执行mysql命令操作了！

7、改mysql的root密码，新密码在此为'leizm'
mysql> set password=password('leizm');
Query OK, 0 rows affected, 1 warning (0.00 sec)

8、设定远程登录mysql。在Linux下为了安全，默认是不允许mysql本机以外的机器访问mysql数据库服务，因此需要重新授权root。方便远程访问。

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> select Host,User from user;
+-----------+-----------+
| Host      | User      |
+-----------+-----------+
| %         | root      |
| localhost | mysql.sys |
| localhost | root      |
+-----------+-----------+
3 rows in set (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON *.* TO root@'%' identified by 'leizm';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

授权语句最后的‘leizm’是mysql数据库root用户的新密码。

9、非必要的步骤，如果远程连不上，估计是防火墙的问题，关闭试试：
[iyunv@localhost mysql]# service iptables stop
setenforce 0iptables：将链设置为政策 ACCEPT：filter        [确定]
iptables：清除防火墙规则：                                 [确定]
iptables：正在卸载模块：                                   [确定]
[iyunv@localhost mysql]# setenforce 0
setenforce: SELinux is disabled

用SQLyog远程登录访问测试下：

安装配置成功！
