MySQL系统安装与部署

database

数据库版本标准化

1.确认Supported Platforms

https://www.mysql.com/support/

2.确认安装版本

推荐:5.7.22 ,8.0.20以后的双数GA版本

3.获取MySQL软件包

https://downloads.mysql.com/archives/community/

4.MD5验证

 

安装与部署

官方安装文档:https://dev.mysql.com/doc/refman/8.0/en/binary-installation.html

1. 部署前准备

1.解压

tar -xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

3. 环境清理

# yum remove -y mariadb-libs

# yum install libaio

4. 创建组

# groupadd mysql

5. 创建用户

# useradd -r -g mysql -s /bin/false mysql

5. 创建目录

# mkdir -p /data/3306/data/

6. 复制以及创建软连接

# cd /usr/local/

# cp /opt/mysql-8.0.24-linux-glibc2.12-x86_64 ./ -rp

# ln -s mysql-8.0.24-linux-glibc2.12-x86_64/ mysql

 

2.部署

1.在mysql下创建目录

[root@localhost local]# cd mysql

[root@localhost mysql]# mkdir mysql-files

2. 授权

[root@localhost mysql]# chown mysql.mysql mysql-files

[root@localhost mysql]# chmod 750 mysql-files/

3. 初始化安装--默认配置

[root@localhost mysql]# ./bin/mysqld --initialize --user=mysql

2022-05-15T09:16:50.594508Z 0 [System] [MY-013169] [Server] /usr/local/mysql-8.0.24-linux-glibc2.12-x86_64/bin/mysqld (mysqld 8.0.24) initializing of server in progress as process 2637

2022-05-15T09:16:50.602884Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.

2022-05-15T09:16:50.995550Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.

2022-05-15T09:16:51.624080Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: tFsl6zx2Cp<l

##默认密码 tFsl6zx2Cp<l

##[root@localhost mysql]# ./bin/mysqld --initialize-insercute --user=mysql 空密码

4. 创建RSA文件和SSL文件确保加密功能 ##银行可能会有,互联网基本不会设置

[root@localhost mysql]# bin/mysql_ssl_rsa_setup

5. 启动mysql

[root@localhost mysql]# ./bin/mysqld_safe --user mysql &

6. 客户端方式登陆mysql

[root@localhost mysql]# mysql -uroot -p"tFsl6zx2Cp<l" -hlocalhost -P3306

7. 修改密码

mysql> ALTER USER USER() IDENTIFIED BY "Chiyu45D";

8. 接口方式登陆

[root@localhost mysql]# ./bin/mysql -uroot -pChiyu45D -S /tmp/mysql.sock

9. 创建用户并赋权

mysql> create user yuyang@localhost identified by "Chiyu45D";

Query OK, 0 rows affected (0.01 sec)

 

mysql> grant all on *.* to yuyang@localhost with grant option;

Query OK, 0 rows affected (0.00 sec)

10. 将mysql命令加入到系统命令

[root@localhost mysql]# vim /etc/profile

在文档最下方加入如下语句:

export PATH=/usr/local/mysql/bin:$PATH

[root@localhost mysql]# source /etc/profile

 

注:系统安装一般用于测试环境,生产环境一般会自定义安装

系统安装会有一些缺点,例如

1、sock文件在/tmp目录下

2、日志文件在/var/log目录下

3、配置文件在/etc/my.cnf目录下
