Linux安裝mysql教程

1，設置安裝路徑

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
日志保存位置：/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上下載，然后用工具（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，創建數據倉庫目錄

--/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用戶禁止登錄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');

--設置root賬戶的host地址（修改了才可以遠程連接）

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

--查看表

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

--這里就可以使用遠程連接測試了；

如提示不能成功連接，可能需要添加需要監聽的端口

/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT

 10，添加系統路徑

# vim /etc/profile
添加：
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

注意：

--退出mysql命令窗口

#exit

 --查看mysql狀態

#service mysql status

--停止mysql

#service mysql stop

--啟動mysql

#service mysql start

12，附my.cnf

/etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.
