Mysql5.7 Linux安裝教程

1系統約定
安裝文件下載目錄：/data/software
Mysql目錄安裝位置：/usr/local/mysql
數據庫保存位置：/data/mysql
日誌保存位置：/data/log/mysql

2下載mysql
在官網：http://dev.mysql.com/downloads/mysql/ 中，選擇如下版本的mysql下載：

執行以下命名：
#mkdir /data/software
#cd /data/software

--下載安裝包 

--建議：在windows上使用迅雷下載，速度很快（個人是1M/s），而後用工具（Xftp）上傳到 /data/software目錄下；
#wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz

3解壓壓縮包到目標位置

#cd /data/software

--解壓壓縮包

#tar -xzvf /data/software/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz

--移動並修改文件名

#mv /data/software/mysql-5.7.17-linux-glibc2.5-x86_64 /usr/local/mysql

4建立數據倉庫目錄

--/data/mysql 數據倉庫目錄
# mkdir /data/mysql         
#ls /data/

5新建mysql用戶、組及目錄
#      ---新建一個msyql組
# useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql     ---新建msyql用戶禁止登陸shell

6改變目錄屬有者

#cd /usr/local/mysql
#pwd
#chown -R mysql .
#chgrp -R mysql .

#chown -R mysql /data/mysql

7配置參數
# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

 此處須要注意記錄生成的臨時密碼，如上文結尾處的：YLi>7ecpe;YP
#bin/mysql_ssl_rsa_setup  --datadir=/data/mysql

 

8修改系統配置文件

#cd /usr/local/mysql/support-files

# cp my-default.cnf /etc/my.cnf
# cp mysql.server /etc/init.d/mysql

# vim /etc/init.d/mysql

修改如下內容：

9啓動mysql

# /etc/init.d/mysql start

--登錄

# mysql -hlocalhost -uroot -p

　　--若是出現：-bash: mysql: command not found

　　--就執行： # ln -s /usr/local/mysql/bin/mysql /usr/bin --沒有出現就不用執行

--輸入第6步生成的臨時密碼

--修改密碼

mysql> set password=password('root');

--設置root帳戶的host地址（修改了才能夠遠程鏈接）

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

--查看錶

mysql> use mysql;
mysql> select host,user from user;

--這裏就能夠使用遠程鏈接測試了；

10添加系統路徑
# vim /etc/profile
添加：
export PATH=/usr/local/mysql/bin:$PATH
以下：

# source /etc/profile

11配置mysql自動啓動
# chmod 755 /etc/init.d/mysql
# chkconfig --add mysql
# chkconfig --level 345 mysql on

以上就是linux環境Mysql 5.7.13安裝教程，但願對你們的學習有所幫助。

 

補充：

--退出mysql命令窗口

#exit

 --查看mysql狀態

#service mysql status

--中止mysql

#service mysql stop

--啓動mysql

#service mysql start

 

 

附my.cnf（這是一個配置mysql配置文件，暫時能夠不用管，如你想鑽研 你能夠百度或google 「mysql my.cnf 配置詳情」）
