64位centos6.7安装mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz

1. 从官网下载 mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz

经测试， 本文还适用于如下版本：
mysql-5.7.10-linux-glibc2.5-x86_64.tar.gz
mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz

官网： http://dev.mysql.com/downloads/mysql/

mysql搜狐镜像站：
http://mirrors.sohu.com/mysql/

# wget -c http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz

2. 创建mysql的用户组/用户, data目录及其用户目录

# groupadd mysql# useradd -g mysql -d /home/mysql mysql# mkdir /home/mysql/data

3. 解压安装包并将解压包里的内容拷贝到mysql的安装目录/home/mysql

# tar -xzvf mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz# cd mysql-5.7.9-linux-glibc2.5-x86_64 # mv * /home/mysql

4. 初始化mysql数据库

# cd /home/mysql# ./bin/mysql_install_db --user=mysql --basedir=/home/mysql --datadir=/home/mysql/data2015-11-10 02:09:17 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize2015-11-10 02:09:23 [WARNING] The bootstrap log isn't empty:2015-11-10 02:09:23 [WARNING] 2015-11-10T10:09:18.114182Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead2015-11-10T10:09:18.129343Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000)2015-11-10T10:09:18.129408Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)

p.s. : mysql5.7新特性：由上面可以看出， mysql_install_db 已经不再推荐使用了，建议改成 mysqld --initialize 完成实例初始化。

# ./bin/mysqld --user=mysql --basedir=/home/mysql --datadir=/home/mysql/data --initialize

改用 mysqld --initialize 后，如果 datadir 指向的目标目录下已经有数据文件, 会出现如下提示：

# ./mysqld --user=mysql --basedir=/home/mysql --datadir=/home/mysql/data --initialize2016-04-08T01:46:53.153530Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).2016-04-08T01:46:53.155856Z 0 [ERROR] --initialize specified but the data directory has files in it. Aborting.2016-04-08T01:46:53.155879Z 0 [ERROR] Aborting

由上可知， 我们需要清空mysql的data目录， 执行清空命令如下：

# cd /home/mysql/data# rm -fr *

然后重新执行初始化命令如下：

# ./bin/mysqld --user=mysql --basedir=/home/mysql --datadir=/home/mysql/data --initialize2016-04-08T01:47:57.556677Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).2016-04-08T01:47:59.945537Z 0 [Warning] InnoDB: New log files created, LSN=457902016-04-08T01:48:00.333528Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.2016-04-08T01:48:00.434908Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: ece26421-fd2b-11e5-a1e3-00163e001e5c.2016-04-08T01:48:00.440125Z 0 [Warning] Gtid table is not ready to be used.

牢记上面的随机密码， 如上**mjT,#x_5sW, 下面我们修改密码时需要用到。

5. 检测下是否能启动mysql服务

# cd /home/mysql# ./support-files/mysql.server startStarting MySQL.. SUCCESS! 

若改用了/home/mysql为mysql的安装目录basedir， 则在启动服务时会出现如下错误：

# ./support-files/mysql.server start./support-files/mysql.server: line 276: cd: /usr/local/mysql: No such file or directoryStarting MySQL ERROR! Couldn't find MySQL server (/usr/local/mysql/bin/mysqld_safe)

由上面可知mysql的tar.gz安装包的默认安装目录为/usr/local/mysql， 这时候我们需要修改/support-files/mysql.server文件的basedir和datadir目录路径为我们环境所在的mysql的basedir和datadir路径， 如下：

# vim support-files/mysql.server--------------------------...basedir=/home/mysqldatadir=/home/mysql/data... --------------------------# ./support-files/mysql.server startStarting MySQL.. SUCCESS! 

6. 创建软链接

# ln -s /home/mysql/bin/mysql /usr/bin/mysql

7. 创建配置文件

将默认生成的my.cnf备份

# mv /etc/my.cnf /etc/my.cnf.bak

进入mysql的安装目录支持文件目录

# cd /home/mysql/support-files

拷贝配置文件模板为新的mysql配置文件,

# cp my-default.cnf /etc/my.cnf

可按需修改新的配置文件选项， 不修改配置选项， mysql则按默认配置参数运行.
如下是我修改配置文件/etc/my.cnf， 设置编码为utf8以防乱码

# vim /etc/my.cnf[mysqld]basedir = /home/mysqldatadir = /home/mysql/datacharacter_set_server=utf8init_connect='SET NAMES utf8'[client]default-character-set=utf8

8. 配置mysql服务开机自动启动

拷贝启动文件到/etc/init.d/下并重命令为mysqld

# cp /home/mysql/support-files/mysql.server /etc/init.d/mysqld

增加执行权限

# chmod 755 /etc/init.d/mysqld

检查自启动项列表中没有mysqld这个，如果没有就添加mysqld：

# chkconfig --list mysqld# chkconfig --add mysqld

设置MySQL在345等级自动启动

# chkconfig --level 345 mysqld on

或用这个命令设置开机启动：

# chkconfig mysqld on

9. mysql服务的启动/重启/停止

启动mysql服务

# service mysqld start

重启mysql服务

# service mysqld restart

停止mysql服务

# service mysqld stop

10. 初始化mysql用户root的密码

先将mysql服务停止

# service mysqld stop

进入mysql安装目录， 执行：

# cd /home/mysql# ./bin/mysqld_safe --skip-grant-tables --skip-networking&[1] 6225[root@localhost mysql]# 151110 02:46:08 mysqld_safe Logging to '/home/mysql/data/localhost.localdomain.err'.151110 02:46:08 mysqld_safe Starting mysqld daemon with databases from /home/mysql/data

另外打开一个终端(p.s. 如果是ssh连接登录的, 另外创建一个ssh连接即可）， 执行操作如下：

# mysql -u root mysqlReading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -AWelcome to the MySQL monitor.

到此， 设置完mysql用户root的密码且确保mysql编码集是utf8, 注意上面， 新版本的mysql.user表里的密码字段是authentication_string

快捷键ctrl + c停止# ./bin/mysqld_safe ...命令， 重新启动mysql服务， 用新密码连接mysql：

# service mysqld startStarting MySQL SUCCESS! [root@localhost bin]# mysql -uroot -pEnter password: Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 3Server version: 5.7.9Copyright (c) 2000, 2015, Oracle and/or its affiliates.

Type '\c' to clear the current input statement.mysql> use mysql;ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.mysql > exit;Bye

咦？又要我改密码， 我们通过mysqladmin来修改密码， 先输入原密码， 再设置新密码， 总算可以了吧！！！

# cd /home/mysql# ./bin/mysqladmin -u root -p passwordEnter password: New password: Confirm new password: Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.# mysql -uroot -pEnter password: Welcome to the MySQL monitor.

Type '\c' to clear the current input statement.mysql> use mysql;Reading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -ADatabase changedmysql> 

或直接：

# ./bin/mysqladmin -uroot -p'**mjT,#x_5sW' password '123456'mysqladmin: [Warning] Using a password on the command line interface can be insecure.Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.

其中， **mjT,#x_5sW就是我们在使用mysqld --initialize时牢记下的随机密码

11. mysql远程授权

格式如下：

mysql> grant all [privileges] on db_name.table_name to 'username'@'host' identified by 'password';

示例如下：

mysql> grant all privileges on *.* to 'root'@'%' identified by '123456';Query OK, 0 rows affected, 1 warning (0.04 sec)mysql> FLUSH PRIVILEGES;Query OK, 0 rows affected (0.00 sec)mysql> 

或用

mysql> grant all on *.* to 'root'@'%' identified by '123456';

到此， 完成了mysql的安装 及配置！！！
