從官網下載mysql-5.6.12-linux-glibc2.5-x86_64.tar.gz
創建mysql用戶
[root@Master home]# useradd mysql [root@Master data]# echo 'mysql'|passwd --stdin mysql
更改用戶 mysql 的密碼 。
passwd： 所有的身份驗證令牌已經成功更新。
創建mysql用戶的原因
不用mysql用戶會出現一下錯誤，嘗試了很多次，添加mysql用戶安裝成功
*當然很多時候我們已經創建好別的用戶，來完成日常的操作如果不創建mysql用戶，修改mysql/bin目錄下的mysqld_safe文件； //親測成功
具體步驟：
[root@Master bin]# vim mysqld_safe user='mysql' 修改為 user='hadoop' //自己的用戶 後邊步驟基本相同* [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用戶下創建data目錄並解壓
[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
設置權限
[root@Master data]# chown -R mysql:mysql mysql
切換用戶並進入mysql/scripts 目錄
[root@Master data]# su mysql [mysql@Master data]$ cd mysql/scripts/ [mysql@Master scripts]$
安裝(目錄根據自己的mysql解壓目錄自行設置)
[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
添加以下兩行
basedir=/home/mysql/data/mysql datadir=/home/mysql/data/mysql/data
配置環境變量
[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服務開機自動啟動
[root@Master bin]# chkconfig --add mysql //添加mysql [root@Master bin]# chkconfig mysql on //設置開機啟動
啟動mysql
[root@Master support-files]# service mysql start env: /etc/init.d/mysql: 權限不夠 //如果出現這個提示 執行以下命令重新啟動 [root@Master support-files]# chmod a+wrx /etc/init.d/mysql [root@Master support-files]# service mysql start Starting MySQL.. SUCCESS! //啟動成功
設置root登錄密碼
[root@Master ~]# cd /home/mysql/data/mysql/bin/ //進去mysql的bin目錄 [root@Master bin]# ./mysqladmin -u root password 'password' //'password' 為自己設置的密碼引號非必須 [root@Master bin]# ./mysqladmin -u root password mysql [root@Master bin]# mysql -u root -p Enter password: Welcome to the MySQL monitor.
