Linux(CentOS6.7) 安裝MySql5.7資料庫
Linux(CentOS6.7) 安裝MySql5.7資料庫 圖文教程
linux(CentOS6.7) 環境Mysql 5.7.17安裝教程分享給大家，供大家參考，具體內容如下：
1系統約定
安裝檔案下載目錄：/data/software
Mysql目錄安裝位置：/usr/local/mysql
資料庫儲存位置：/data/mysql
日誌儲存位置：/data/log/mysql
2下載mysql
在官網：http://dev.mysql.com/downloads/mysql/ 中，選擇以下版本的mysql下載：
執行如下命名：
#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（我的是1M/s），然後用工具（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
–移動並修改檔名
#mv /data/software/mysql-5.7.17-linux-glibc2.5-x86_64 /usr/local/mysql
4建立資料倉庫目錄
–/data/mysql 資料倉庫目錄
mkdir /data/mysql
#ls /data/
5新建mysql使用者、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使用者禁止登入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配置引數
bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
此處需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修改系統配置檔案
#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
修改以下內容：
9啟動mysql
/etc/init.d/mysql start
–登陸
mysql -hlocalhost -uroot -p
–如果出現：-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’);
–設定root賬戶的host地址（修改了才可以遠端連線）
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;
–這裡就可以使用遠端連線測試了；
10新增系統路徑
vim /etc/profile
新增：
export PATH=/usr/local/mysql/bin:$PATH
如下：
source /etc/profile
11配置mysql自動啟動
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，希望對大家的學習有所幫助。
補充：
–退出mysql命令視窗
#exit
–檢視mysql狀態
#service mysql status
–停止mysql
#service mysql stop
–啟動mysql
#service mysql start
附my.cnf（這是一個配置mysql配置檔案，暫時可以不用管，如你想鑽研 你可以百度或google “mysql my.cnf 配置詳情”）
/etc/my.cnf
