将MySQL数据库的动态链接库共享至系统链接库

一般MySQL数据库还会被类似于PHP等服务调用，所以我们需要将MySQL编译后的lib库文件添加至当前Linux主机链接库/etc/ld.so.conf.d/下，这样MySQL服务就可以被其它服务调用了。

[root@www bin]# echo "/data/company/company_program/mysql-5.7.34/lib" > /etc/ld.so.conf.d/mysql.conf

[使生效]

创建其它MySQL数据库用户(未使用)
使用MySQL数据库root管理员用户登录MySQL数据库后，可以管理数据库和其他用户了。这里演示创建一个名为typecodes的MySQL用户（密码为@typecodes2014.com）和一个名为typecodes的数据库。

[root@typecodes mysql]# mysql -uroot -p密码

######登录成功后，创建typecodes数据库，并设置字符集和字符校
mysql> CREATE DATABASE `typecodes` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
Query OK, 1 row affected (0.00 sec)

######创建名为typecodes用户，并让它拥有typecodes数据库所有的权限
mysql> grant all privileges on typecodes.* to typecodes@localhost identified by '@typecodes2014.com';
Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> exit;            [创建完毕，root用户退出]

授权可以远程访问
https://www.cnblogs.com/xiaofu007/p/10513845.html

//grant all privileges on *.* to root@'%'identified by 'passwd';
GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "自己设置好的root密码";
flush privileges;

GRANT ALL PRIVILEGES ON . TO root@"%" IDENTIFIED BY "Ttwis@8852";
设置可以远程访问

阿里云或者腾讯云记得在“本实例安全组”中开放必要的端口，比如mysql的3306。

查看端口

netstat -nupl (UDP类型的端口)
netstat -ntpl (TCP类型的端口)

重启mysql

service mysqld restart

service mysqld start

设置开机自启动
创建用于启动MySQL的配置文件

[root@localhost ~]# touch /usr/lib/systemd/system/mysqld.service
[root@localhost ~]# cd /usr/lib/systemd/system

vim mysqld.service

[Unit]
Description=MySQL Server
Documentation=man:mysqld(8)
Documentation=http://dev.mysql.com/doc/refman/en/using-systemd.html
After=network.target
After=syslog.target

[Install]
WantedBy=multi-user.target

[Service]
User=mysql
Group=mysql
ExecStart=/data/company/company_program/mysql-5.7.34/bin/mysqld --defaults-file=/etc/my.cnf
LimitNOFILE = 5000

修改mysqld.service所属用户组，保持和配置文件一致

chown -R mysql:mysql mysqld.service

启动MySQL

systemctl start mysqld

设置自启动

systemctl enable mysqld

重启

reboot

查看MySQL是否自启动

ps -ef|grep mysql

修改密码：

1.关闭mysql服务

 net stop mysql 

2.找到mysql安装路径找到 my.ini 打开在 [mysqld] 下添加 skip-grant-tables 跳过密码校验 3.登陆mysql mysql -uroot -p密码随便输入

4.进入MySQL 改密码

mysql> update mysql.user set authentication_string=password('123456') where user='root' and Host = 'localhost';    ///123456自己的新密码

*特别提醒注意的一点是，新版的mysql数据库下的user表中已经没有Password字段了

5.记得把my.ini中的 skip-grant-tables 去掉否则谁都可以登陆我们的数据库了</pre>
