centos6.5系统使用tar包离线安装mysql5.7

安装环境：centos6
###1、下载

• 1.1、 http://dev.mysql.com/downloads/mysql/
  http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.10-linux-glibc2.5-i686.tar.gz
• 1.2、将tar包复制到/usr/local/soft/目录下

###2、解压缩到/usr/local/

[root@localhost local]# cd /usr/local/soft/
[root@localhost soft]# tar zvxf mysql-5.7.10-linux-glibc2.5-i686.tar.gz -C /usr/local
[root@localhost soft]# cd ..
[root@localhost local]# mv /usr/local/mysql-5.7.10-linux-glibc2.5-i686 /usr/local/mysql

###3、在mysql下面创建data数据库文件目录

[root@localhost local]# mkdir /usr/local/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

[root@localhost local]# groupadd mysql
[root@localhost local]# useradd mysql -g mysql
[root@localhost local]# cd mysql
[root@localhost mysql]# pwd
/usr/local/mysql
[root@localhost mysql]# chown -R mysql .  
[root@localhost mysql]# chgrp -R mysql .   

###5、初始化mysql并启动mysql服务

[root@localhost mysql]# cd /usr/local/mysql/bin
[root@localhost bin]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
2016-01-09 12:00:28 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2016-01-09 12:00:33 [WARNING] The bootstrap log isn't empty:
2016-01-09 12:00:33 [WARNING] 2016-01-09T04:00:29.262989Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead
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)

报警可以忽略

###6、修改my.cnf

[root@localhost mysql]# vim /etc/my.cnf
# 将datadir=/var/lib/mysql修改为实际的安装路径 如 datadir=/usr/local/mysql/data
[root@localhost mysql]# vim /etc/selinux/config
# 把SELINUX=enforcing改为SELINUX=disabled后存盘退出重启机器

###7、创建sock文件目录

[root@localhost mysql]# mkdir -p /var/lib/mysql
[root@localhost mysql]# chown mysql:mysql /var/lib/mysql

###8、 建立sock文件软连接

[root@localhost bin]# ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

###9、启动mysql

[root@localhost bin]# cd /usr/local/mysql/support-files
[root@localhost support-files]# ./mysql.server start

###10、配置mysql环境变量

[root@localhost bin]# vim /etc/profile
export MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin

###11、获取mysql初始化密码，登录mysql，修改密码

[root@localhost ~]# cat /root/.mysql_secret
[root@localhost ~]# cd /usr/local/mysql/bin
[root@localhost bin]# ./mysql -uroot -p:5ul#d6dkcwX

mysql: [Warning] Using a password on the command line interface can be insecure.

mysql>

• 11.5、如上，显示登录成功，可以执行mysql命令操作了！

###12、改mysql的root密码，新密码在此为’root’

mysql> set password=password('root');
Query OK, 0 rows affected, 1 warning (0.00 sec)

###13、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。

mysql> grant all privileges on *.* to 'root'@'%' identified by 'root' with grant option;
grant all privileges on *.* to 'root’@'centos1' identified by 'root' with grant option;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

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)

###14、将mysql配置到服务并设置开机启动

• 14.1、将mysql配置为服务mysql

[root@centos1 mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

• 14.2、将mysql服务设置为开机启动

[root@centos1 mysql]# chkconfig mysql on

• 14.3、启动mysql服务

[root@centos1 mysql]# service mysql start

###15、报错解决

• 15.1、如果远程连不上，估计是防火墙的问题，关闭试试：

[root@centos1 mysql]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[root@centos1 mysql]# service iptables status
iptables: Firewall is not running.

• 15.2、解决报错：mysqld_safe Directory ‘/var/lib/mysql’ for UNIX socket file don’t exists.

mkdir -p /var/lib/mysql
chown mysql:mysql /var/lib/mysql

• 15.3、解决报错：Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
