Linux下安装MySQL5.7并配置bin log模式

1、从MySQL官网下载MYSQL的安装文件

mysql-5.7.25-1.el6.x86_64.rpm-bundle.tar

百度网盘下载地址：

链接：https://pan.baidu.com/s/1wZ9twbHvFduKZAwrMyHDYg
提取码：76tg

2、创建mysql组

groupadd mysql

3、创建mysql用户

useradd -g mysql mysql

4、创建mysql文件夹并把安装包放在mysql文件夹中

mkdir /mysql
mv mysql-5.7.25-1.el6.x86_64.rpm-bundle.tar /mysql

5、检查库文件是否存在，如有删除

[root@mysql Desktop]$ rpm -qa | grep mysql
mysql-libs-5.1.52-1.el6_0.1.x86_64
[root@mysql ~]# rpm -e mysql-libs-5.1.52.x86_64 --nodeps

6、解压安装包

[root@mysql mysql]# tar -xvf mysql-5.7.25-1.el6.x86_64.rpm-bundle.tar
mysql-community-common-5.7.25-1.el6.x86_64.rpm

7、进行安装（请按照如下顺序进行安装）

[root@mysql mysql]# rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm --nodeps
warning: mysql-community-common-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

    package mysql-community-test-5.7.25-1.el6.x86_64 is already installed

8、检查并启动mysqld服务

[root@mysql mysql]# service mysqld status
mysqld is stopped
[root@mysql mysql]#  service mysqld start
Initializing MySQL database:                               [  OK  ]
Starting mysqld:                                           [  OK  ]
[root@mysql mysql]# service mysqld status
mysqld (pid  3781) is running...

9、登录mysql并修改密码

检查临时密码：

[root@mysql mysql]# more /var/log/mysqld.log | grep "A temporary password"
2019-04-26T07:05:10.073912Z 1 [Note] A temporary password is generated for root@localhost: Pykq_5blTgr1

登录：
[root@mysql mysql]# mysql -hlocalhost -p
Enter password:

mysql>

10、修改密码策略，第一条为修改为只需满足长度要求，第二条为设置长度最低为4，此处设置小于4也会按4处理

mysql> set global validate_password_policy=0;
Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password_length=4;
Query OK, 0 rows affected (0.00 sec)

11、修改密码

mysql> set password=password('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)

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

12、登录mysql

[root@mysql mysql]# mysql -hlocalhost -p123456
mysql: [Warning] Using a password on the command line interface can be insecure.
Welcome to the MySQL monitor.  Commands end with ; or \g.

mysql>

至此mysql安装完成。

13、允许远程连接并设置远程连接的密码

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)

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

14、日志模式

检查日志模式

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

mysql> show variables like 'log_bin';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| log_bin       | OFF   |
+---------------+-------+
1 row in set (0.00 sec)

15、设置bin log模式

在/etc/my.cnf中添加：

log_bin=binary-log

server_id=1

 

重启mysqld服务

service mysqld restart

16、查看bin log模式是否设置成功

mysql>  show variables like 'log_bin';
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...
Connection id:    3
Current database: *** NONE ***

+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| log_bin       | ON    |
+---------------+-------+
1 row in set (0.00 sec)
