rpm安裝mysql
rpm安裝mysql
需要下載mysql的四個rpm包：
mysql-community-client-5.7.18-1.el6.x86_64.rpm
mysql-community-common-5.7.18-1.el6.x86_64.rpm
mysql-community-libs-5.7.18-1.el6.x86_64.rpm
mysql-community-server-5.7.18-1.el6.x86_64.rpm
1、rpm -qa | grep -i mysql
2、將上一步找到的mysql相關的包都刪除
rpm -e --nodeps mysql-libs* //*號指代實際包名， 請實際情況輸入完整包名
rpm -e mysql-server*（如果有）
rpm -e mysql-client*（如果有）
3、檢查並刪除老版本mysql的開發標頭檔案和庫
命令：
rm -fr /usr/lib/mysql
rm -fr /usr/include/mysql
注意：解除安裝後/var/lib/mysql中的資料及/etc/my.cnf不會刪除，如果確定沒用後就手工刪除
rm -f /etc/my.cnf
rm -fr /var/lib/mysql
rm -fr /usr/share/mysql
4、安裝perl
yum install perl -y
5、下載numactl-2.0.9-2.el6.x86_64.rpm並安裝
rpm -ivh numactl-2.0.9-2.el6.x86_64.rpm
6、安裝mysql（有順序要求）
rpm -ivh mysql-community-common-5.7.18-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.19-1.el6.x86_64.rpm
rpm -ivh mysql-community-client-5.7.19-1.el6.x86_64.rpm
rpm -ivh mysql-community-server-5.7.19-1.el6.x86_64.rpm
7、#修改配置檔案位置
[
如果需要更改預設的data資料夾， 請提前更改my.cnf中datadir目錄，
socket和pid-file建議還是使用預設的目錄/var/lib/mysql
8、修改/etc/my.cnf檔案，設定資料庫的編碼方式：
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
character_set_server=utf8
9、如果出現錯誤，請檢視/etc/my.cnf檔案中指定的錯誤log日誌的檔案
10、service mysqld start
11、找到隨機密碼：
在/var/log/mysqld.log中有一行：
A temporary password is generated for
# mysql -uroot -p"yAe7QGVJ;HlR"使用隨機密碼登入系統
12、修改預設密碼：
set global validate_password_policy=0;
set global validate_password_length=6;
set password for 'root'@'localhost'=password('123456');
搞定
13、設定密碼以及檢視編碼方式
mysql> set global validate_password_policy=0;
Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_length=6;
Query OK, 0 rows affected (0.00 sec)
mysql> set password for 'root'@'localhost'=password('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> show variables like '%character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
mysql>
14、給root設定遠端登入許可權
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
15、chkconfig mysqld on 設定開機啟動
至此，mysql-5.7安裝完畢！

1.Q:
file /usr/share/mysql/charsets/cp850.xml from install of mysql-community-common-5.7.19-1.el6.x86_64 conflicts with file from package mariadb-libs-1:5.5.56-2.el7.x86_64
Re：
是mariadb-libs-1:5.5.56-2.el7.x86_64包衝突了，把它缷掉即可。
rpm -e mariadb-libs-1:5.5.56-2.el7.x86_64 --nodeps
