linux下MySQL5.7 rpm安装方式记录，供大家参考，具体内容如下

删除旧包：

# rpm -qa | grep -i mysql# rpm -ev mysql-libs-* --nodeps

安装rpm包：

# rpm -ivh mysql-community-common-5.7.17-1.el7.x86_64.rpm# rpm -ivh mysql-community-libs-5.7.17-1.el7.x86_64.rpm# rpm -ivh mysql-community-client-5.7.17-1.el7.x86_64.rpm# rpm -ivh mysql-community-server-5.7.17-1.el7.x86_64.rpm

启动、停止：

# service mysqld start# service mysqld stop# service mysqld status

初始随机密码：

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

修改初始密码及授权远程访问：

# mysql -uroot -pmysql> 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）

# mkdir /data/mysql/data# mv /var/lib/mysql/* /data/mysql/data/# mkdir /data/mysql/log# chown mysql:mysql -R /data/mysql# touch mysqld_safe.log# chown mysql:mysql mysqld_safe.log# vi /etc/my.cnf/**[client]port = 3306socket = /data/mysql/log/mysql.sockdefault-character-set=utf8[mysql]no-auto-rehashsocket=/data/mysql/log/mysql.sockdefault-character-set=utf8[mysqld]port = 3306socket = /data/mysql/log/mysql.sockcharacter-set-server=utf8lower_case_table_names=1basedir=/usrdatadir=/data/mysql/datalog-error=/data/mysql/log/error.logpid-file=/data/mysql/log/mysql.pidinit_connect='SET NAMES utf8'symbolic-links=0skip-external-lockingkey_buffer_size = 16Mmax_allowed_packet = 1Mtable_open_cache = 64sort_buffer_size = 512Knet_buffer_length = 8Kread_buffer_size = 256Kread_rnd_buffer_size = 512Kmyisam_sort_buffer_size = 8M[mysqld_safe]log-error=/data/mysql/log/mysqld_safe.log*/# getenforceEnforcing# setenforce 0# vi /etc/selinux/config/**# This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:# enforcing - SELinux security policy is enforced.# permissive - SELinux prints warnings instead of enforcing.# disabled - No SELinux policy is loaded.#SELINUX=enforcingSELINUX=disabled# SELINUXTYPE= can take one of these two values:# targeted - Targeted processes are protected,# mls - Multi Level Security protection.SELINUXTYPE=targeted */# service mysqld start

其他命令：

# mysqladmin -u root -p passwordmysql> select version();# chkconfig --list# chkconfig --level 345 mysqld on# netstat -na | grep 3306
