這篇具有很好參考價值的文章主要介紹了二進制方式安裝MySQL并備份數據庫。希望對大家有所幫助。如果存在錯誤或未考慮完全的地方，請大家不吝賜教，您也可以點擊"舉報違法"按鈕提交疑問。

一、openEuler二進制方式安裝MySQL 8.0.28版本

1.1 獲取軟件包

[root@openEuler3 ~]# wget -c https://mirrors.aliyun.com/mysql/MySQL-8.0/mysql-8.0.28-linux-glibc2.12-x86_64.tar.xz

1.2 解壓軟件包

[root@openEuler3 ~]#  dnf install -y tar xz
[root@openEuler3 ~]# tar xf mysql-8.0.28-linux-glibc2.12-x86_64.tar.xz -C /usr/local/
[root@openEuler3 ~]# ln -sv /usr/local/mysql-8.0.28-linux-glibc2.12-x86_64/ /usr/local/mysql
'/usr/local/mysql' -> '/usr/local/mysql-8.0.28-linux-glibc2.12-x86_64/'

1.3?創(chuàng)建用戶和用戶組

[root@openEuler3 ~]# groupadd -g 27 -r mysql
[root@openEuler3 ~]# useradd -u 27 -g 27 -c 'MySQL Server' -r -s /sbin/nologin mysql

1.4 創(chuàng)建目錄并修改權限

[root@openEuler3 ~]# cd /usr/local/mysql
[root@openEuler3 mysql]# mkdir mysql-files
[root@openEuler3 mysql]# chown mysql:mysql mysql-files
[root@openEuler3 mysql]# chmod 750 mysql-files

1.5 安裝

[root@openEuler3 mysql]#  bin/mysqld --initialize --user=mysql
2024-02-21T03:03:21.878690Z 0 [System] [MY-013169] [Server] /usr/local/mysql-8.0.28-linux-glibc2.12-x86_64/bin/mysqld (mysqld 8.0.28) initializing of server in progress as process 5067

2024-02-21T03:03:22.366051Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.
2024-02-21T03:03:23.332212Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: wy11ZhmyaU-7
[root@openEuler3 mysql]# bin/mysql_ssl_rsa_setup
[root@openEuler3 mysql]# bin/mysqld_safe --user=mysql &
[1] 5115
[root@openEuler3 mysql]# Logging to '/usr/local/mysql/data/openEuler3.err'.
[root@openEuler3 mysql]# 2024-02-21T03:03:42.947144Z mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data

1.6 配置環(huán)境變量

[root@openEuler3 mysql]# vim /etc/profile.d/mysql.sh
export PATH=$PATH:/usr/local/mysql/bin/
[root@openEuler3 mysql]# source /etc/profile.d/mysql.sh
[root@openEuler3 mysql]# dnf install -y ncurses-compat-libs

1.7 測試并修改密碼

[root@openEuler3 mysql]# mysql -uroot -p'wy11ZhmyaU-7'

mysql> alter user root@localhost identified by '*********';
Query OK, 0 rows affected (0.01 sec)

1.8 提供服務腳本

#停止服務
[root@openEuler3 mysql]# mysqladmin -uroot -p'*********' shutdown
[root@openEuler3 mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@openEuler3 mysql]# chkconfig --add mysqld
[root@openEuler3 ~]# vim /etc/my.cnf

1.9 測試

[root@openEuler3 etc]# systemctl start mysqld
[root@openEuler3 etc]# systemctl status mysqld

二、創(chuàng)建數據庫并備份數據庫

2.1 創(chuàng)建數據庫和數據表

mysql> create database school;
Query OK, 1 row affected (0.01 sec)

mysql> use school
Database changed
mysql> CREATE  TABLE  student (
    -> id  INT(10)  NOT NULL  UNIQUE  PRIMARY KEY,
    -> name  VARCHAR(20)  NOT NULL,
    -> sex  VARCHAR(4),
    -> birth  YEAR,
    -> department  VARCHAR(20),
    -> address  VARCHAR(50)
    -> );
Query OK, 0 rows affected, 1 warning (0.02 sec)

mysql> CREATE  TABLE  score (
    -> id  INT(10)  NOT NULL  UNIQUE  PRIMARY KEY  AUTO_INCREMENT,
    -> stu_id  INT(10)  NOT NULL,
    -> c_name  VARCHAR(20),
    -> grade  INT(10)
    -> );
Query OK, 0 rows affected, 3 warnings (0.01 sec)

2.2 插入數據

mysql> select * from student;
+-----+-----------+------+-------+--------------+--------------------+
| id  | name      | sex  | birth | department   | address            |
+-----+-----------+------+-------+--------------+--------------------+
| 901 | 張老大    | 男   |  1985 | 計算機系     | 北京市海淀區(qū)       |
| 902 | 張老二    | 男   |  1986 | 中文系       | 北京市昌平區(qū)       |
| 903 | 張三      | 女   |  1990 | 中文系       | 湖南省永州市       |
| 904 | 李四      | 男   |  1990 | 英語系       | 遼寧省阜新市       |

| 906 | 王六      | 男   |  1988 | 計算機系     | 湖南省衡陽市       |
+-----+-----------+------+-------+--------------+--------------------+
6 rows in set (0.00 sec)

mysql> select * from score;
+----+--------+-----------+-------+
| id | stu_id | c_name    | grade |
+----+--------+-----------+-------+
|  1 |    901 | 計算機    |    98 |
|  2 |    901 | 英語      |    80 |
|  3 |    902 | 計算機    |    65 |
|  4 |    902 | 中文      |    88 |
|  5 |    903 | 中文      |    95 |
|  6 |    904 | 計算機    |    70 |
|  7 |    904 | 英語      |    92 |
|  8 |    905 | 英語      |    94 |
|  9 |    906 | 計算機    |    90 |
| 10 |    906 | 英語      |    85 |
+----+--------+-----------+-------+
10 rows in set (0.00 sec)

2.3 備份數據庫school到/backup目錄

①代碼

[root@openEuler3 ~]# mkdir /backup/
[root@openEuler3 ~]# cd /backup/
[root@openEuler3 backup]# mysqldump -uroot -p'*********' --opt -B school > school.sql
mysqldump: [Warning] Using a password on the command line interface can be insecure.
[root@openEuler3 backup]# more school.sql

②結果

2.4?備份MySQL數據庫為帶刪除表的格式，能夠讓該備份覆蓋已有數據庫而不需要手動刪除原有數據庫

①代碼

[root@openEuler3 backup]# mysqldump --add-drop-table -uroot -p'*********' -d school > /backup/drop.sql
mysqldump: [Warning] Using a password on the command line interface can be insecure.
[root@openEuler3 backup]# more drop.sql

②結果?

2.5?直接將MySQL數據庫壓縮備份?

[root@openEuler3 backup]# mysqldump -uroot -p'*********' school | gzip > /backup/gzip.sql.gz
mysqldump: [Warning] Using a password on the command line interface can be insecure.
[root@openEuler3 backup]# ll
total 12
-rw-r--r-- 1 root root 2355 Feb 21 11:39 drop.sql
-rw-r--r-- 1 root root 1173 Feb 21 11:44 gzip.sql.gz
-rw-r--r-- 1 root root 3558 Feb 21 11:33 school.sql
