linux安裝軟體的方式多種多樣,MySQL也不例外,本文將介紹MySQL所有的安裝方式。
二.關於MySQL的安裝
MySQL一般可以採用四種安裝方式,每種方式各有優點,使用場景各有不同:
- yum安裝MySQL,優點:簡單,方便,適用場景:可以訪問網路的環境
- 離線源碼編譯安裝MySQL,優點:可定製,適用性強,適用場景:無網路,需要定製MySQL,平臺相容性不強(記憶體最好大於4G不然編譯會出現記憶體不足的報錯)
- RPM包安裝MySQL,優點:簡單,方便,適用場景:redhat系統
- 通用二進位包安裝MySQL,優點:簡單,好維護,適用場景:大部分環境都適用(推薦)
三.部署規劃
3.1 伺服器規劃
伺服器 | 操作系統版本 | CPU架構 | MySQL安裝方式 |
---|---|---|---|
node6 | CentOS Linux release 7.4.1708 | x86_64 | 源碼編譯安裝MySQL |
node7 | CentOS Linux release 7.4.1708 | x86_64 | 通用二進位包安裝MySQL |
node8 | CentOS Linux release 7.4.1708 | x86_64 | RPM包安裝MySQL |
node9 | CentOS Linux release 7.4.1708 | x86_64 | yum安裝MySQL |
3.2 資料庫目錄規劃
文件類型 | 文件部署位置 |
---|---|
數據目錄datadir | /data/data(/data目錄請確保足夠大) |
配置文件my.cnf | /etc/my.cnf |
錯誤日誌log-error | /data/log/mysql_error.log |
二進位日誌log-bin | /data/binlogs/mysql-bin(用於資料庫恢復和主從複製,以及審計(audit)操作) |
慢查詢日誌slow_query_log_file | /data/log/mysql_slow_query.log |
套接字文件socket | /data/run/mysql.sock |
進程ID文件mysql.pid | /data/run/mysql.pid |

5.11 進行MySQL安全初始化(可選)
[root@node7 system]# mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root: #這裡輸入MySQL初始化時生成的密碼(grep 'temporary password' /data/log/mysql_error.log)
The existing password for the user account root has expired. Please set a new password.
New password: #輸入新密碼
Re-enter new password:
VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?
Press y|Y for Yes, any other key for No: n #y安裝MySQL密碼插件
Using existing password for root.
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n
... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y #y移除匿名用戶
Success.
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : n #是否允許root遠程登錄
... skipping.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y #是否移除test資料庫
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y #刷新許可權表
Success.
All done!
5.12 修改密碼,給用戶賦許可權(根據自己情況賦許可權)
[root@node7 ~]# mysql -uroot -p111111

Bye
--------------------------------------------------------------------------------------
#以下是為MySQL賦許可權的介紹
mysql> grant 許可權1,許可權2,…許可權n on 資料庫名稱.表名稱 to 用戶名@用戶地址 identified by ‘連介面令’;
許可權1,許可權2,…許可權n代表select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file等14個許可權。
當許可權1,許可權2,…許可權n被all privileges或者all代替,表示賦予用戶全部許可權。
當資料庫名稱.表名稱被*.*代替,表示賦予用戶操作伺服器上所有資料庫所有表的許可權。
用戶地址可以是localhost,也可以是ip地址、機器名字、功能變數名稱。也可以用’%'表示從任何地址連接。
‘連介面令’不能為空,否則創建失敗。
比如:
mysql>grant select,insert,update,delete,create,drop on vtdc.employee to [email protected] identified by ‘123′;
給來自10.163.225.87的用戶joe分配可對資料庫vtdc的employee表進行select,insert,update,delete,create,drop等操作的許可權,並設定口令為123。
mysql>grant all privileges on vtdc.* to [email protected] identified by ‘123′;
給來自10.163.225.87的用戶joe分配可對資料庫vtdc所有表進行所有操作的許可權,並設定口令為123。
--------------------------------------------------------------------------------------
5.13 導入時區信息到MySQL庫
[root@node7 system]# mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -uroot -p111111 mysql
#執行上述操作之後,time_zone,time_zone_leap_second,time_zone_name,time_zone_transition ,time_zone_transition_type表就有時區數據了
[root@node7 system]# mysql -uroot -p111111 mysql

自此,通用二進位包安裝MySQL完畢。
六.使用RPM包安裝MySQL
6.1 上傳MySQL的RPM包到/usr/local/src目錄下
[root@node8 local]# cd /usr/local/src/
[root@node8 src]# ls
mysql-community-client-5.7.23-1.el7.x86_64.rpm mysql-community-libs-5.7.23-1.el7.x86_64.rpm
mysql-community-common-5.7.23-1.el7.x86_64.rpm mysql-community-libs-compat-5.7.23-1.el7.x86_64.rpm
mysql-community-devel-5.7.23-1.el7.x86_64.rpm mysql-community-server-5.7.23-1.el7.x86_64.rpm
6.2 安裝RPM包
[root@node8 src]# rpm -ivh ./*.rpm
warning: ./mysql-community-client-5.7.23-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:

mariadb-libs is obsoleted by mysql-community-libs-compat-5.7.23-1.el7.x86_64
#出現上述錯誤說明:和mariadb-libs組件衝突,卸載mariadb-libs相關組件即可
[root@node8 src]# rpm -qa | grep mariadb* #查看mariadb-libs相關的組件
mariadb-libs-5.5.56-2.el7.x86_64
[root@node8 src]# rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64 #卸載mariadb-libs組件
warning: /etc/my.cnf saved as /etc/my.cnf.rpmsave
[root@node8 src]# rpm -ivh ./*.rpm

6.3 啟動MySQL,修改密碼,為用戶賦權
[root@node8 src]# service mysqld status
Redirecting to /bin/systemctl status mysqld.service
● mysqld.service - MySQL Server
Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)

http://dev.mysql.com/doc/refman/en/using-systemd.html
[root@node8 src]# service mysqld start

[root@node8 src]# grep password /var/log/mysqld.log

mysql> SET PASSWORD = PASSWORD('123456');#修改root密碼為123456,如果提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements,則說明密碼設置太簡單,如果想設置123456這樣的簡單密碼,可在SQL中執行:
#mysql> set global validate_password_policy=0;
#mysql> set global validate_password_length=1;
#這樣再次執行SET PASSWORD = PASSWORD('123456')就可成功。
Query OK, 0 rows affected, 1 warning (0.01 sec)
mysql> UPDATE mysql.user SET authentication_string =PASSWORD('123456') WHERE User='mysql'; #修改MySQL的mysql用戶的密碼為123456

mysql> exit;
Bye
--------------------------------------------------------------------------------------
#以下是為MySQL賦許可權的介紹
mysql> grant 許可權1,許可權2,…許可權n on 資料庫名稱.表名稱 to 用戶名@用戶地址 identified by ‘連介面令’;
許可權1,許可權2,…許可權n代表select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file等14個許可權。
當許可權1,許可權2,…許可權n被all privileges或者all代替,表示賦予用戶全部許可權。
當資料庫名稱.表名稱被*.*代替,表示賦予用戶操作伺服器上所有資料庫所有表的許可權。
用戶地址可以是localhost,也可以是ip地址、機器名字、功能變數名稱。也可以用’%'表示從任何地址連接。
‘連介面令’不能為空,否則創建失敗。
比如:
mysql>grant select,insert,update,delete,create,drop on vtdc.employee to [email protected] identified by ‘123′;
給來自10.163.225.87的用戶joe分配可對資料庫vtdc的employee表進行select,insert,update,delete,create,drop等操作的許可權,並設定口令為123。
mysql>grant all privileges on vtdc.* to [email protected] identified by ‘123′;
給來自10.163.225.87的用戶joe分配可對資料庫vtdc所有表進行所有操作的許可權,並設定口令為123。
--------------------------------------------------------------------------------------
自此MySQL的RPM安裝就完畢了,此方法自動生成/etc/my.cnf,查看配置文件可知道MySQL的日誌目錄和數據目錄。
七.使用yum安裝MySQL
7.1 下載並安裝MySQL官方的 Yum Repository
