                        <p>linux下MySQL5.7 rpm安装方式记录，供大家参考，具体内容如下</p>

删除旧包：

  1. rpm -qa | grep -i mysql
  2. rpm -ev mysql-libs-* --nodeps

安装rpm包：

  1. rpm -ivh mysql-community-common-5.7.17-1.el7.x86_64.rpm
  2. rpm -ivh mysql-community-libs-5.7.17-1.el7.x86_64.rpm
  3. rpm -ivh mysql-community-client-5.7.17-1.el7.x86_64.rpm
  4. rpm -ivh mysql-community-server-5.7.17-1.el7.x86_64.rpm

启动、停止：

  1. service mysqld start
  2. service mysqld stop
  3. service mysqld status

初始随机密码：

  1. cat /var/log/mysqld.log | more

修改初始密码及授权远程访问：

  1. mysql -uroot -p mysql> set password='Pwd@123456'; mysql> grant all privileges on . to 'root'@'%' identified by 'Pwd@123456';

密码复杂度属性：

mysql> set global validate_password_policy=0;

validate_password_policy有以下取值：（默认是1，即MEDIUM，所以刚开始设置的密码必须符合长度，且必须含有数字，小写或大写字母，特殊字符。）

修改数据目录：

 新目录需要给mysql用户授权，mysqld_safe日志文件授权，关闭selinux（没找到相关策略设置的方法）

  1. mkdir /data/mysql/data
  2. mv /var/lib/mysql/* /data/mysql/data/
  3. mkdir /data/mysql/log
  4. chown mysql:mysql -R /data/mysql
  5. touch mysqld_safe.log
  6. chown mysql:mysql mysqld_safe.log
  7. vi /etc/my.cnf /** [client] port = 3306 socket = /data/mysql/log/mysql.sock default-character-set=utf8

[mysql] no-auto-rehash socket=/data/mysql/log/mysql.sock default-character-set=utf8

[mysqld] port = 3306 socket = /data/mysql/log/mysql.sock character-set-server=utf8 lower_case_table_names=1 basedir=/usr datadir=/data/mysql/data log-error=/data/mysql/log/error.log pid-file=/data/mysql/log/mysql.pid init_connect='SET NAMES utf8' symbolic-links=0

skip-external-locking key_buffer_size = 16M max_allowed_packet = 1M table_open_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M

[mysqld_safe] log-error=/data/mysql/log/mysqld_safe.log */

  1. getenforce Enforcing
  2. setenforce 0
  3. vi /etc/selinux/config /**
  4. This file controls the state of SELinux on the system.
  5. SELINUX= can take one of these three values:
  6. enforcing - SELinux security policy is enforced.
  7. permissive - SELinux prints warnings instead of enforcing.
  8. disabled - No SELinux policy is loaded. #SELINUX=enforcing SELINUX=disabled
  9. SELINUXTYPE= can take one of these two values:
  10. targeted - Targeted processes are protected,
  11. mls - Multi Level Security protection. SELINUXTYPE=targeted */
  12. service mysqld start

其他命令：

  1. mysqladmin -u root -p password mysql> select version();

  2. chkconfig --list

  3. chkconfig --level 345 mysqld on

  4. netstat -na | grep 3306
