服務(wù)器

本實例要求下載并安裝調(diào)試mysql數(shù)據(jù)庫。

10余年的遂寧網(wǎng)站建設(shè)經(jīng)驗，針對設(shè)計、前端、開發(fā)、售后、文案、推廣等六對一服務(wù)，響應(yīng)快，48小時及時工作處理。全網(wǎng)營銷推廣的優(yōu)勢是能夠根據(jù)用戶設(shè)備顯示端的尺寸不同，自動調(diào)整遂寧建站的顯示方式，使網(wǎng)站能夠適用不同顯示終端，在瀏覽器中調(diào)整網(wǎng)站的寬度，無論在任何一種瀏覽器上瀏覽網(wǎng)站，都能展現(xiàn)優(yōu)雅布局與設(shè)計，從而大程度地提升瀏覽體驗。創(chuàng)新互聯(lián)建站從事“遂寧網(wǎng)站設(shè)計”,“遂寧網(wǎng)站推廣”以來，每個客戶項目都認(rèn)真落實執(zhí)行。

第一步：下載Mysql數(shù)據(jù)庫安裝所需的全部軟件。

我已提前下載好數(shù)據(jù)庫軟件，直接在服務(wù)器下載即可，如下：

通過scp直接下載：

[root@agt20 ~]# scp root@192.168.122.10:/root/MYSQL* /root/

軟件如下圖：

[root@agt20 ~]# ls mysql-*
mysql-5.7.17.tar
mysql-community-client-5.7.17-1.el7.x86_64.rpm
mysql-community-common-5.7.17-1.el7.x86_64.rpm
mysql-community-devel-5.7.17-1.el7.x86_64.rpm
mysql-community-embedded-5.7.17-1.el7.x86_64.rpm
mysql-community-embedded-compat-5.7.17-1.el7.x86_64.rpm
mysql-community-embedded-devel-5.7.17-1.el7.x86_64.rpm
mysql-community-libs-5.7.17-1.el7.x86_64.rpm
mysql-community-libs-compat-5.7.17-1.el7.x86_64.rpm
mysql-community-minimal-debuginfo-5.7.17-1.el7.x86_64.rpm
mysql-community-server-5.7.17-1.el7.x86_64.rpm
mysql-community-test-5.7.17-1.el7.x86_64.rpm

第二步：通過yum進行安裝，起服務(wù)器并查看

[root@agt20 ~]# yum -y install mysql-*.rpm
[root@agt20 ~]# systemctl restart mysqld
[root@agt20 ~]# systemctl enable mysqld
[root@agt20 ~]# systemctl status mysqld.service 
\\u25cf mysqld.service - MySQL Server
Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)

Docs: man:mysqld(8)
http://dev.mysql.com/doc/refman/en/using-systemd.html

10\\u6708 15 11:29:11 agt20.tedu.cn systemd[1]: Started MySQL Server.
[root@agt20 ~]#

第三步：連接MySQL服務(wù)器，修改密碼；

1）查看初始密碼

[root@agt20 ~]# grep -i \'password\' /var/log/mysqld.log 
2019-10-15T03:28:55.200931Z 1 [Note] A temporary password is generated for root@localhost: r3qhDysMrM)

2）使用初始密碼連接mysql服務(wù)

[root@agt20 ~]# mysql -uroot -p\'r3qhDysMrM)\'
mysql: [Warning] Using a password on the command line interface can be insecure.

mysql>

3）重置數(shù)據(jù)庫管理員roo本機登錄密碼

mysql> alter user root@localhost identified by \'Pwd@123...\';
Query OK, 0 rows affected (0.00 sec)

4）修改密碼策略

mysql> set global validate_password_policy=0;
Query OK, 0 rows affected (0.01 sec)
mysql> set global validate_password_length=6;
Query OK, 0 rows affected (0.00 sec)
mysql> alter user root@localhost identified by \'pwd@123\';
Query OK, 0 rows affected (0.00 sec)

5）使用修改后的密碼登錄

[root@agt20 ~]# mysql -uroot -ppwd@123
mysql: [Warning] Using a password on the command line interface can be insecure.
