启动服务
安装后检查服务状态:
# systemctl status mysql Unit mysql.service could not be found. [root@hostname nginx]# systemctl status mysqld ● mysqld.service - MySQL 8.0 database server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: enabled) Active: inactive (dead) |
默认开机启动。
安装后,未启动。
启动服务:
# systemctl start mysqld.service |

验证服务器
安装后,可以使用 mysql 的 root 用户(root@localhost) 访问,默认 不需要密码。
默认端口 3306。

查看 默认数据库,有 4个。
mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sys | +--------------------+ 4 rows in set (0.00 sec)
|
用户表 user 在 mysql 数据库中。
mysql> desc mysql.user;
|
查看 mysql.user 表的用户基本信息:
mysql> select user,host,authentication_string,plugin from mysql.user;
注意,这里的 dev@localhost 账号是 后面自己添加的,不是系统默认的。

注意,可以给 没有密码的 root 用户添加密码的。

mysqld
服务器命令(ps -ef 中可见)。
# whereis mysqld mysqld: /usr/sbin/mysqld /usr/libexec/mysqld /usr/share/man/man8/mysqld.8.gz
# ls /usr/sbin | grep mysql mysqld
# ls /usr/libexec | grep mysql mysql-check-socket mysql-check-upgrade mysqld mysql-prepare-db-dir mysql-scripts-common mysql-wait-stop
|
服务器配置
配置文件位于:/etc/my.cnf.d 目录下(/etc/my.cnf 指向这里)。
# cat ../my.cnf # # This group is read both both by the client and the server # use it for options that affect everything # [client-server]
# # include all files from the config directory # !includedir /etc/my.cnf.d
|
# pwd /etc/my.cnf.d
my.cnf.d]# ls client.cnf mysql-default-authentication-plugin.cnf mysql-server.cnf
|
mysql-server.cnf 文件内容(默认)
|
执行 服务器配置 修改:
在 /etc/my.cnf.d/ mysql-server.cnf 添加下面的内容:
# 端口
port=33306
# 默认字符集 character_set_server=utf8mb4
|
说明,utf8mb4 支持 emoji 表情等,真正的 utf8。ben发布于博客园
修改服务器后,重启mysql:
# systemctl restart mysqld.service |
成功。

创建 mysql 用户及授权
针对 本文的 mysql version 8。
执行:创建
mysql> create user 'dev'@'%' identified by 'password'; Query OK, 0 rows affected (0.01 sec) |
没有授权的 用户,登录后 只能看到 2个数据库:
mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | performance_schema | +--------------------+ 2 rows in set (0.00 sec)
|
查看此时的权限
mysql> show grants for 'dev'@'%'; +---------------------------------+ | Grants for dev@% | +---------------------------------+ | GRANT USAGE ON *.* TO `dev`@`%` | +---------------------------------+ 1 row in set (0.00 sec)
|
执行:授权
mysql> grant all privileges on *.* to 'dev'@'%'; Query OK, 0 rows affected (0.01 sec) |
授予了所有权限。
注意,存在风险,真实情况应该根据需要授权。权限名称 可以参考 mysql.user 表 的 以“_priv” 几位的字段名。
