linux安裝mysql5.7.24

1、檢查是否已安裝過mariadb，若有便刪除（linux系統自帶的）

[[email protected] /]# rpm -qa | grep mariadb
[[email protected] /]# rpm -e --nodeps mariadb-libs-5.5.44-2.el7.centos.x86_64

2、檢查是否已安裝過mysql，若有便刪除（linux系統自帶的）

[[email protected] /]# rpm -qa | grep mysql
[[email protected] /]# rpm -e –-nodeps mysql-libs-5.1.52.x86_64

3、檢查mysql組和使用者是否存在，如無建立：

  [[email protected] ~]# cat /etc/group | grep mysql

  [[email protected] ~]# cat /etc/passwd |grep mysql

  [[email protected] ~]# groupadd mysql

  [[email protected] ~]# useradd -r -g mysql mysql

4、從官網下載mysql安裝包，解壓後移動到/usr/local/mysql下

5、在mysql下新增data目錄

[[email protected] ~]# mkdir /usr/local/mysql/data

6、更改mysql目錄下所有的目錄及資料夾所屬組合使用者

[[email protected] /]# cd /usr/local/ 
[[email protected] local]# chown -R mysql:mysql mysql/
[[email protected] local]# chmod -R 755 mysql/

7、編譯安裝並初始化mysql，記住命令列末尾的密碼：

[[email protected] local]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql

8、啟動mysql服務

　[[email protected] local]# /usr/local/mysql/support-files/mysql.server start

9、做個軟連線，重啟服務

[[email protected] local]# ln -s /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql 
[[email protected] local]# service mysql restart
Shutting down MySQL.. SUCCESS! 
Starting MySQL. SUCCESS!

10、做個軟連結，將安裝目錄下的mysql 放在/usr/bin 目錄下

[[email protected] local]# ln -s /usr/local/mysql/bin/mysql /usr/bin

11、登入msyql，輸入密碼（密碼為步驟7初始化生成的密碼）

[[email protected] local]# mysql -u root -p
Enter password:

12、修改密碼並開放遠端

msql>alter user 'root'@'localhost' identified by '123456';
mysql>use mysql;
msyql>update user set user.Host='%' where user.User='root';
mysql>flush privileges;
mysql>quit

13、編輯my.cnf，新增配置檔案，配置內容為

[[email protected] local]# vi /usr/local/mysql/my.cnf
[mysqld]
port = 3306
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

14、設定開機自啟動

1、將服務檔案拷貝到init.d下，並重命名為mysql
[[email protected] local]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
2、賦予可執行許可權
[[email protected] local]# chmod +x /etc/init.d/mysqld
3、新增服務
[[email protected] local]# chkconfig --add mysqld
4、顯示服務列表
[[email protected] local]# chkconfig --list
5、重啟伺服器
[[email protected] local]# reboot
