创建用户

[root@localhost mysql]# useradd -r -M -s /sbin/nologin mysql

解压至指定目录

[root@localhost mysql]# tar xf mysql-5.7.33-linux-glibc2.12-x86_64.tar.gz -C /usr/local

创建软链接或者修改目录名

[root@localhost local]# mv mysql-5.7.33-linux-glibc2.12-x86_64/ mysql
[root@localhost local]# ls
apache  apr-util  etc    include  lib64    mysql  share
apr     bin       games  lib      libexec  sbin   src

修改属主和属组

[root@localhost local]# chown -R mysql.mysql /usr/local/mysql/
[root@localhost local]# ll
drwxr-xr-x.  9 mysql mysql 129 五月    4 20:40 mysql

设置环境变量（因为不是用yum装的，找不到mysql程序）

[root@localhost mysql]# vim /etc/profile.d/mysql.sh
export PATH=/usr/local/mysql/bin:$PATH
[root@localhost mysql]# . /etc/profile.d/mysql.sh
[root@localhost mysql]# which mysql
/usr/local/mysql/bin/mysql

创建存放数据的目录并修改属主属组

需要一个空间大的目录，或者将目录创建后将硬盘设备挂载在此目录上

[root@localhost mysql]# mkdir /opt/mysql_data
[root@localhost mysql]# chown -R mysql.mysql /opt/mysql_data/
[root@localhost mysql]# ll /opt
drwxr-xr-x. 2 mysql mysql 6 五月    4 20:58 mysql_data

初始化并保存密码

[root@localhost mysql]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/opt/mysql_data/        //初始化    控制mysql的用户        数据存放目录

写配置文件

[root@localhost mysql]# vim /etc/my.cnf
[mysqld]
basedir = /usr/local/mysql            //程序位置
datadir = /opt/mysql_data            //数据存放位置
socket = /tmp/mysql.sock            //文件套接字位置
port = 3306                                    //端口
pid-file = /opt/mysql_data/mysql.pid        //进程文件位置
user = mysql                                //用户
skip-name-resolve                        //跳过域名解析，即直接在内网使用ip连接数据库

配置启动脚本和开机自启

[root@localhost ~]# cp -a /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@localhost ~]# sed -ri 's#^(basedir=).*#\1/usr/local/mysql#g' /etc/init.d/mysqld

Mysql的配置文件

mysql的配置文件为/etc/my.cnf

配置文件查找顺序：若在多个配置文件中均有设定，则最后找到的配置文件中的配置生效

/etc/my.cnf --> /etc/mysql/my.cnf --> --default-extra-file=/PATH/TO/CONF_FILE --> ~/.my.cnf

备份与恢复

数据库常用备份方案

数据库备份方案：

• 全量备份
• 增量备份
• 差异备份

mysql备份工具mysqldump

mysqldump 语法：

     mysqldump [OPTIONS] database [tables ...]                                                //备份数据表
    mysqldump [OPTIONS] --all-databases [OPTIONS]                                    //备份全部数据库
    mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...]            //备份某个数据库
    -uUSERNAME      //指定数据库用户名
    -hHOST          //指定服务器主机，请使用ip地址
    -pPASSWORD      //指定数据库用户的密码
    -P#             //指定数据库监听的端口，这里的#需用实际的端口号代替

备份所有数据库

[root@localhost ~]# mysqldump -uroot -p  --all-databases > /mysql_dump/all_20210504.sql
Enter password:
[root@localhost ~]# ls /mysql_dump/
all_20210504.sql

备份某个数据库

[root@localhost ~]# mysqldump -uroot -p  --databases hanao > /mysql_dump/hanao_db_20210504.sql
Enter password:
[root@localhost ~]# ls /mysql_dump/
all_20210504.sql  hanao_db_20210504.sql

备份某个数据表

[root@localhost ~]# mysqldump -uroot -p hanao student > /mysql_dump/student_table_20210504.sql
Enter password:
[root@localhost ~]# ls /mysql_dump/
all_20210504.sql  hanao_db_20210504.sql  student_table_20210504.sql

数据中没有后面新增的数据

恢复差异备份

查看误删数据库的操作在什么地方

可以看到drop命令开始之前的Pos是1034，所以我们用1034恢复到数据删除之前

使用mysqlbinlog恢复差异备份

可以看到之前新增的数据也恢复回来了
