MySQL系统安装与部署，

MySQL系统安装与部署，

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
