64位Aliyun Linux 15.1安装mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz

---

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

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

2 . 解压安装包并将解压包里的内容拷贝到mysql的安装目录/usr/local/mysql/
注：如果你的安装路径不是默认/usr/local/mysql/则需要修改配置文件

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

3.创建mysql的用户组/用户, data目录及其用户目录

# groupadd mysql# useradd -r -g mysql mysql# mkdir /usr/local/mysql/data

4 . 初始化mysql数据库

# cd /usr/local/mysql# ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

5 . 检测下是否能启动mysql服务

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

6 . 创建软链接

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

7 . 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 /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

8 .增加执行权限

# chmod 755 /etc/init.d/mysqld

9 .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

10 .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

11 . 初始化mysql用户root的密码
先将mysql服务停止,进入mysql安装目录， 执行：

# cd /usr/local/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

12 .另外打开一个终端， 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.

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.

到此， 完成了mysql的安装 及配置！！！
