本文主要介紹了centos7.3 安裝mysql5.7.18的詳細教學,需要的朋友可以參考下，希望能幫助到大家。
1查看Linux發行版本
[root@typecodes ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
2下載MySQL官方的Yum Repository
根據Linux發行版本（CentOS、Fedora都屬於紅帽系），從mysql官方（http://dev.mysql.com/downloads/repo/yum/）取得Yum Repository。
[root@typecodes ~]# wget -i http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm --2016-02-03 18:36:02-- http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm Resolving dev.mysql.com (dev.mysql.com)... 137.254.60.11 Connecting to dev.mysql.com (dev.mysql.com)|137.254.60.11|:80... connected.

[root@typecodes ~]# clear</mysql-build>
最後的截圖：
4 啟動資料庫：
[root@typecodes ~]# systemctl start mysqld.service
然後使用指令systemctl status mysqld.service查看MySQL資料庫啟動後的服務狀態：
5 取得初始密碼
#使用YUM安裝並啟動MySQL服務後，MySQL程序會自動在進程日誌中列印root用戶的初始密碼：
#######从mysql进程日志中获取root用户的初始密码：ra%yk7urCBIh [root@typecodes ~]# grep "password" /var/log/mysqld.log 2016-02-03T10:42:17.272166Z 1 [Note] A temporary password is generated for root@localhost: ra%yk7urCBIh 2016-02-03T10:42:36.776875Z 2 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:42:52.063138Z 3 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:42:57.564373Z 4 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:43:01.477007Z 5 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:46:03.642008Z 6 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:46:11.217889Z 7 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:47:44.755199Z 0 [Note] Shutting down plugin 'validate_password' 2016-02-03T10:47:46.505844Z 0 [Note] Shutting down plugin 'sha256_password' 2016-02-03T10:47:46.505851Z 0 [Note] Shutting down plugin 'mysql_native_password'
6 修改root用戶密碼
使用小節5中取得的root用戶的初始密碼，然後進行修改：
set global validate_password_policy =0;//預設是1，即MEDIUM，所以剛開始設定的密碼必須符合長度，且必須含有數字，小寫或大寫字母，特殊字元。
set global validate_password_length=4;//指定了密码中数据的长度 alter user root@localhost identified by 'crow';//修改密码
增加遠端存取權限
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'crow' WITH GRANT OPTION; FLUSH PRIVILEGES;
退出mysql，然後重新啟動服務
systemctl restart mysqld
防火牆開啟3306連接埠
firewall-cmd --zone=public --add-port=3306/tcp --permanent
重新啟動防火牆
firewall-cmd --reload [root@typecodes ~]# mysql -uroot -p Enter password: #######输入默认的root密码后回车 Welcome to the MySQL monitor. Commands end with ; or \g.

Type '\c' to clear the current input statement. mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password'; Query OK, 0 rows affected (0.00 sec) mysql> exit Bye
7 安裝完成
至此，使用在CentOS7中使用YUM方法安裝MySQL5.7.10資料庫完成。如下所示，可以使用新的root密碼登陸MySQL了。
[root@typecodes ~]# mysql -uroot -ppassword mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g.

附錄1：查看MySQL資料庫的設定資訊
MySQL的設定檔仍是/etc/my.cnf，其它安裝資訊可以透過mysql_config指令查看。其中，動態庫檔案存放在/usr/lib64/mysql目錄下。
附錄2：對於C/C++等開發者
#由於需要用到類似mysql.h等頭文件，需要執行下面的指令安裝mysql開發版本即可。
[root@typecodes ~]# yum -y install mysql-community-devel
附錄3：刪除MySQL的Repository
因為小節3中安裝了MySQL的Yum Repository，所以以後每次執行yum操作時，都會去檢查更新。如果想要去掉這種自動檢查操作的話，可以使用以下命令卸載MySQL的Repository即可。
[root@typecodes ~]# yum -y remove mysql57-community-release-el7-7.noarch update 2017.04.10 11:10
使用上面的yum方法也可以安裝目前mysql官網上最新的版本mysql5.7.18。只要替換小節2中rmp包的版本即可，後續操作步驟不變。
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
