CentOS7默認安裝MariaDB而不是MySQL,而且yum服務器上也移除了MySQL相關的軟件包.因為MariaDB和MySQL可能會沖突,故先卸載MariaDB.MYSQL入門

1、安裝新版mysql之前,我們需要將系統(tǒng)自帶的mariadb-lib卸載
?MYSQL入門

1. [root@iZwz94qazh62gk5ewl4ei2Z?home]#?rpm?-qa?|?grep?-i?mariadb?
2. ?mariadb-libs-5.5.52-1.el7.x86_64?
3. [root@iZwz94qazh62gk5ewl4ei2Z?home]#?rpm?-e?--nodeps?mariadb-libs-5.5.52-1.el7.x86_64?

?MYSQL入門

2、到mysql的官網(wǎng)下載最新版mysql的rpm集合包：mysql-5.7.18-1.el6.x86_64.rpm-bundle.tarMYSQL入門

3、上傳mysql-5.7.18-1.el6.x86_64.rpm-bundle.tar到linux服務器,并解壓tar包
?MYSQL入門

1. [root@iZwz94qazh62gk5ewl4ei2Z?home]#?mkdir?mysql?
2. [root@iZwz94qazh62gk5ewl4ei2Z?home]#?tar?-xf?mysql-5.7.18-1.el6.x86_64.rpm-bundle.tar?-C?mysql?

上面幾個包有依賴關系,執(zhí)行有先后.MYSQL入門

使用rpm安裝方式安裝mysql,安裝的路徑如下：MYSQL入門

a 數(shù)據(jù)庫目錄
/var/lib/mysql/
b 配置文件
/usr/share/mysql(mysql.server命令及配置文件)
c 相關命令
/usr/bin(mysqladmin mysqldump等命令)
d 啟動腳本
/etc/rc.d/init.d/(啟動腳本文件mysql的目錄)MYSQL入門

e /etc/my.confMYSQL入門

5、 數(shù)據(jù)庫初始化MYSQL入門

為了保證數(shù)據(jù)庫目錄為與文件的所有者為 mysql 登陸用戶,如果你的linux系統(tǒng)是以 root 身份運行 mysql 服務,需要執(zhí)行下面的命令初始化
?MYSQL入門

1. [root@iZwz94qazh62gk5ewl4ei2Z?mysql]#?mysqld?--initialize?--user=mysql?

?MYSQL入門

如果是以 mysql 身份登錄運行,則可以去掉 --user 選項.MYSQL入門

另外 --initialize 選項默認以“安全”模式來初始化,則會為 root 用戶生成一個密碼并將該密碼標記為過期,登陸后你需要設置一個新的密碼,MYSQL入門

而使用 --initialize-insecure 命令則不使用安全模式,則不會為 root 用戶生成一個密碼.MYSQL入門

這里演示使用的 --initialize 初始化的,會生成一個 root 賬戶密碼,密碼在log文件里,紅色區(qū)域的就是自動生成的密碼

?MYSQL入門

1. [root@iZwz94qazh62gk5ewl4ei2Z?mysql]#?cat?/var/log/mysqld.log?

?MYSQL入門

?現(xiàn)在啟動mysql數(shù)據(jù)庫systemctl start mysqld.service(Centos7特有的啟動方式)MYSQL入門

[root@iZwz94qazh62gk5ewl4ei2Z mysql]# systemctl start mysqld.service

可以使用下面兩個命令對mysql進行停止,啟動和重啟：MYSQL入門

啟動：MYSQL入門

使用 service 啟動：service mysqld start
使用 mysqld 腳本啟動：/etc/inint.d/mysqld start
使用 safe_mysqld 啟動：safe_mysqld&

停止：MYSQL入門

使用 service 啟動：service mysqld stop
使用 mysqld 腳本啟動：/etc/inint.d/mysqld stop
mysqladmin shutdown 

重啟：MYSQL入門

使用 service 啟動：service mysqld restart
使用 mysqld 腳本啟動：/etc/inint.d/mysqld restart

連接數(shù)據(jù)庫MYSQL入門

[root@iZwz94qazh62gk5ewl4ei2Z mysql]# mysql -u root -p 
Enter password:

密碼輸入： ?:Wu?2QQutQwjMYSQL入門

修改密碼：MYSQL入門

set password = password('你的密碼');

設置遠程訪問MYSQL入門

grant all privileges on *.* to 'root' @'%' identified by '123456'; 
flush privileges;

設置mysql開機啟動MYSQL入門

1. 加入到系統(tǒng)服務：?
2. chkconfig?--add?mysqld?
3. 自動啟動：?
4. chkconfig?mysqld?on?
5. 查詢列表：?
6. chkconfig?
7. ?
8. 說明：都沒關閉(off)時是沒有自動啟動.?
