1.下載rpm檔案
wget https://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm
[[email protected] /]# wget https://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm--2019-01-02 18:11:58-- https://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm正在解析主機 dev.mysql.com... 137.254.60.11 正在連線 dev.mysql.com|137.254.60.11|:443... 已連線。 已發出 HTTP 請求，正在等待迴應... 302 Found 位置：https://repo.mysql.com//mysql57-community-release-el6-9.noarch.rpm [跟隨至新的 URL] --2019-01-02 18:12:03-- https://repo.mysql.com//mysql57-community-release-el6-9.noarch.rpm 正在解析主機 repo.mysql.com... 23.76.232.185 正在連線 repo.mysql.com|23.76.232.185|:443... 已連線。 已發出 HTTP 請求，正在等待迴應... 200 OK 長度：9216 (9.0K) [application/x-redhat-package-manager] 正在儲存至: “mysql57-community-release-el6-9.noarch.rpm” 100%[===================================================>] 9,216 --.-K/s in 0s 2019-01-02 18:12:04 (52.9MB/s) - 已儲存 “mysql57-community-release-el6-9.noarch.rpm” [9216/9216])
2.安裝rpm包
rpm -Uvh mysql57-community-release-el6-9.noarch.rpm
[[email protected] /]# rpm -Uvh mysql57-community-release-el6-9.noarch.rpm warning: mysql57-community-release-el6-9.noarch.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ########################################### [100%] 1:mysql57-community-relea########################################### [100%]
安裝成功後，會在/etc/yum.repos.d/下面多幾個mysql的包
[[email protected] /]# cd /etc/yum.repos.d/ [[email protected] yum.repos.d]# ll 總用量 40 -rw-r--r--. 1 root root 1991 5月 19 2016 CentOS-Base.repo -rw-r--r--. 1 root root 647 5月 19 2016 CentOS-Debuginfo.repo -rw-r--r--. 1 root root 289 5月 19 2016 CentOS-fasttrack.repo -rw-r--r--. 1 root root 630 5月 19 2016 CentOS-Media.repo -rw-r--r--. 1 root root 6259 5月 19 2016 CentOS-Vault.repo -rw-r--r--. 1 root root 957 11月 5 2012 epel.repo -rw-r--r--. 1 root root 1056 11月 5 2012 epel-testing.repo -rw-r--r--. 1 root root 1414 9月 12 2016 mysql-community.repo -rw-r--r--. 1 root root 1440 9月 12 2016 mysql-community-source.repo
3.安裝mysql (此過程需要時間)
yum install mysql-community-server

4.開啟mysql服務
[[email protected] /]# service mysqld start 初始化 MySQL 資料庫： [失敗] [[email protected] /]# service mysqld start 正在啟動 mysqld： [確定] //正常啟動
5.mysql安裝完成會建立臨時預設的超級使用者，密碼儲存在/var/log/mysqld.log，命令檢視密碼：
grep 'temporary password' /var/log/mysqld.log
[[email protected] /]# grep 'temporary password' /var/log/mysqld.log 2019-01-02T10:37:02.765238Z 1 [Note] A temporary password is generated for [email protected]: 7?0?dyl3Uduj (密碼)
6.使用預設使用者'root'@'localhost'登入資料庫並且修改密碼：
[[email protected] /]# mysql -u root -p
[[email protected] /]# mysql -u root -p Enter password: （上面的密碼） Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.7.24 Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
修改密碼：
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456'; Query OK, 0 rows affected (0.00 sec)
注意：如果出現錯誤提示：
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
這個是因為密碼過於簡單，密碼必須符合長度，包含數字、大寫小寫字母、特殊字元。
7.開啟遠端連線
1）.設定防火牆iptables開放3306介面
在/etc/sysconfig下面有個iptables檔案，在倒數第二行新增埠就可以
在控制檯輸入：
iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
[[email protected] /]# iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
2）.然後進行儲存：
[[email protected] /]# service iptables save iptables：將防火牆規則儲存到 /etc/sysconfig/iptables： [確定]
更新防火牆規則：service iptables restart
刪除：iptables -D INPUT -p tcp --dport 3306 -j ACCEPT
8.修改mysql許可權，將localhost修改為%
1).登入mysql
mysql -u root -p
2).登入到 mysql 這個表
mysql> use mysql; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed
3)..將root的host修改為%
mysql> update user set host = '%' where user ='root'; Query OK, 1 row affected (0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0
4).重新載入許可權
mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
5).輸入：
mysql> select host,user from user where user='root'; +------+------+ | host | user | +------+------+ | % | root | +------+------+ 1 row in set (0.00 sec)
9.Navicat 遠端連線
