从官网下载mysql-5.6.12-linux-glibc2.5-x86_64.tar.gz
创建mysql用户
[root@Master home]# useradd mysql [root@Master data]# echo 'mysql'|passwd --stdin mysql
更改用户 mysql 的密码 。
passwd： 所有的身份验证令牌已经成功更新。
创建mysql用户的原因
不用mysql用户会出现一下错误，尝试了很多次，添加mysql用户安装成功
*当然很多时候我们已经创建好别的用户，来完成日常的操作如果不创建mysql用户，修改mysql/bin目录下的mysqld_safe文件； //亲测成功
具体步骤：
[root@Master bin]# vim mysqld_safe user='mysql' 修改为 user='hadoop' //自己的用户 后边步骤基本相同* [root@Slave1 data]# service mysql start Starting MySQL...... ERROR! The server quit without updating PID file (/home/hadoop/ruanJian/mysql/data/Slave1.Hadoop.pid). [root@Master data]#vim Slave1.Hadoop.err //查看日志文件 160830 15:56:44 mysqld_safe Starting mysqld daemon with databases from /home/hadoop/ruanJian/mysql/data 2016-08-30 15:56:49 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2016-08-30 15:56:49 1990 [ERROR] Fatal error: Can't change to run as user 'mysql' ; Please check that the user exists! 2016-08-30 15:56:49 1990 [ERROR] Aborting 2016-08-30 15:56:49 1990 [Note] Binlog end 2016-08-30 15:56:49 1990 [Note] /home/hadoop/ruanJian/mysql/bin/mysqld: Shutdown complete 160830 15:56:49 mysqld_safe mysqld from pid file /home/hadoop/ruanJian/mysql/data/Slave1.Hadoop.pid ended
在mysql用户下创建data目录并解压
[root@Master data]# tar -zxvf mysql-5.6.12-linux-glibc2.5-x86_64.tar.gz [root@Master data]# mv mysql-5.6.12-linux-glibc2.5-x86_64 mysql //重命名
设置权限
[root@Master data]# chown -R mysql:mysql mysql
切换用户并进入mysql/scripts 目录
[root@Master data]# su mysql [mysql@Master data]$ cd mysql/scripts/ [mysql@Master scripts]$
安装(目录根据自己的mysql解压目录自行设置)
[mysql@Master scripts]$ ./mysql_install_db --user=mysql --basedir=/home/mysql/data/mysql --datadir=/home/mysql/data/mysql/data

To do so, start the server, then issue the following commands: /home/mysql/data/mysql/bin/mysqladmin -u root password 'new-password' /home/mysql/data/mysql/bin/mysqladmin -u root -h Master.Hadoop password 'new-password' Alternatively you can run: /home/mysql/data/mysql/bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd . ; /home/mysql/data/mysql/bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd mysql-test ; perl mysql-test-run.pl Please report any problems with the ./bin/mysqlbug script! The latest information about MySQL is available on the web at http://www.mysql.com Support MySQL by buying support/licenses at http://shop.mysql.com New default config file was created as /home/mysql/data/mysql/my.cnf and will be used by default by the server when you start it. You may edit this file to change server settings WARNING: Default config file /etc/my.cnf exists on the system This file will be read by default by the MySQL server If you do not want to use this, either remove it, or use the --defaults-file argument to mysqld_safe when starting the server
配置文件
[mysql@Master scripts]$ cd ../support-files/ [root@Master support-files]# cp my-default.cnf /etc/my.cnf [root@Master support-files]# cp mysql.server /etc/init.d/mysql [root@Master support-files]# vim /etc/init.d/mysql //修改mysql文件
添加以下两行
basedir=/home/mysql/data/mysql datadir=/home/mysql/data/mysql/data
配置环境变量
[root@Master support-files]# vim /etc/profile #set mysql environment export MYSQL_HOME=/home/mysql/data/mysql export PATH=$MYSQL_HOME/bin:$PATH
配置mysql服务开机自动启动
[root@Master bin]# chkconfig --add mysql //添加mysql [root@Master bin]# chkconfig mysql on //设置开机启动
启动mysql
[root@Master support-files]# service mysql start env: /etc/init.d/mysql: 权限不够 //如果出现这个提示 执行以下命令重新启动 [root@Master support-files]# chmod a+wrx /etc/init.d/mysql [root@Master support-files]# service mysql start Starting MySQL.. SUCCESS! //启动成功
设置root登录密码
[root@Master ~]# cd /home/mysql/data/mysql/bin/ //进去mysql的bin目录 [root@Master bin]# ./mysqladmin -u root password 'password' //'password' 为自己设置的密码引号非必须 [root@Master bin]# ./mysqladmin -u root password mysql [root@Master bin]# mysql -u root -p Enter password: Welcome to the MySQL monitor.
