1、首先關閉linux的防火牆，執行命令

chkconfig iptables off

2、從mysql官網上下載自己適合的mysql版本https://dev.mysql.com/downloads/mysql/5.6.html#downloads，進入mysql官網，依次點擊

 

 

 

 

 

3、下載後的mysql檔案

mysql-5.6.40-linux-glibc2.12-i686.tar.gz

 

 將下載好的mysql壓縮檔放置在linux的/usr/local檔案夾下，解壓該壓縮檔

 tar -zxvf mysql-5.6.40-linux-glibc2.12-i686.tar.gz

 

將解壓後的檔案重新命名為mysql

mv mysql-5.6.40-linux-glibc2.12-i686 mysql

 

4、建立mysql使用者組及使用者

groupadd mysqluseradd -r -g mysql mysql

 

5、進入到mysql目錄，執行添加MySQL配置的操作

cp support-files/my-medium.cnf /etc/my.cnf或：cp support-files/my-default.cnf /etc/my.cnf

 

是否覆蓋？按y 斷行符號

6、編輯/etc/my.cnf檔案；

vi /etc/my.cnf

 

在my.cnf檔案中添加或者修改相關配置，更改完成後儲存退出

 1 # For advice on how to change settings please see 2 # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html 3 # *** DO NOT EDIT THIS FILE. It‘s a template which will be copied to the 4 # *** default location during install, and will be replaced if you 5 # *** upgrade to a newer version of MySQL. 6  7 [mysqld] 8  9 # Remove leading # and set to the amount of RAM for the most important data10 # cache in MySQL.

7、在mysql目前的目錄下設定目錄的存取權限（注意後面的小點，表示目前的目錄）

chown -R mysql .chgrp -R mysql .scripts/mysql_install_db --user=mysqlchown -R root .chown -R mysql data

 

8、初始化資料（在mysql/bin或者mysql/scripts下有個 mysql_install_db 可執行檔初始化資料庫），進入mysql/bin或者mysql/scripts目錄下，執行下面命令

./mysql_install_db --verbose --user=root --defaults-file=/etc/my.cnf --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql --pid-file=/usr/local/mysql/data/mysql.pid --tmpdir=/tmp

 

9、啟動mysql，進入/usr/local/mysql/bin目錄，執行下面命令

./mysqld_safe --defaults-file=/etc/my.cnf --socket=/tmp/mysql.sock --user=root &

 

注意，如果游標停留在螢幕上，表示啟動成功，需要我們先關閉shell終端，再開啟一個新的shell終端，不要執行退出操作。如果出現 mysql ended這樣的語句，表示Mysql沒有正常啟動，你可以到log中尋找問題. 

10、設定開機啟動，新開啟shell中斷後，進入mysql目錄，執行下面命令

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqldcp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql

chmod 700 /etc/init.d/mysqlchkconfig --add mysqldchkconfig --level 2345 mysqld onchown mysql:mysql -R /usr/local/mysql/

 

重啟linux

reboot

 

查看mysql狀態

service mysqld status

 

11、添加遠端存取許可權

　　（1）、添加mysql命令

ln  -s /usr/local/mysql/bin/mysql  /usr/bin  （mysql的安裝路徑）

 

　　（2）、更改存取權限

登入mysql,執行下面命令mysql -uroot -p 密碼為空白直接斷行符號,運行以下兩條命令GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘duan‘ with grant option;Flush privileges;

 

退出mysql

exit

重啟linux,就完成了

reboot

 

註：本機訪問mysql，root賬戶預設是沒有密碼的，連接埠號碼預設3306，如果需要修改root賬戶密碼，在/usr/local/mysql/bin目錄下，執行下面命令

./mysqladmin -h 127.0.0.1 -P3306 -uroot password ‘duan‘exit
