下载MYSQL安装包

华为开源镜像站_软件开发服务_华为云

上面的选择一个下载

或者用命令下载

wget https://repo.huaweicloud.com/kunpeng/yum/el/7/aarch64/Packages/database/mysql-5.7.27-1.el7.aarch64.rpm

检查是否已经安装MySQL

rpm -qa | grep mysql

将包卸载掉

rpm -e --nodeps  python2-mysqlclient-1.3.12-8.ky10.aarch64
rpm -e --nodeps  qt5-qtbase-mysql-5.11.1-13.p01.ky10.aarch64
rpm -e --nodeps  pcp-pmda-mysql-4.1.3-13.p04.ky10.aarch64

开始安装

rpm -ivh mysql-5.7.27-1.el7.aarch64.rpm

找到my.cnf

find / -name "my.cnf"

查看my.cnf

 cat  /etc/my.cnf

修改my.cnf

修改后的my.cnf 如下：

[mysqld]
# mysql 安装目录
basedir=/usr/local/mysql
# msyql 数据存放目录
datadir=/usr/local/mysql/data
# 设置端口
port = 3306
socket=/tmp/mysql.socksymbolic-links=0
log-error=/var/log/mysqld.log
# pid-file=/tmp/mysqld/mysqld.pid
sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'
[client]
default-character-set=utf8[mysql]
# 默认字符集
default-character-set=utf8[mysqld]
log-bin=mysql-bin 
binlog-format=ROW 
expire_logs_days = 3
server_id=1 
# 最大连接数
max_connections=1000init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake

进入mysql目录

cd /usr/local/mysq

没有msyql 数据存放目录

datadir=/usr/local/mysql/data

创建data目录

mkdir data

添加mysql用户组和mysql用户

groupadd -r mysql && useradd -r -g mysql -s /sbin/nologin -M mysql

提示已经存在不需要创建

授权mysql文件

chown -R mysql /usr/local/mysql/

添加环境变量

vim /etc/profile

添加下面内容：

export MYSQL_HOME=/usr/local/mysqlexport PATH=$PATH:$MYSQL_HOME/bin

使环境变量生效

 source /etc/profile

查看mysql是否启动

ps -ef | grep mysql

启动mysql

service mysql start

报错了解决问题吧

Starting MySQL... ERROR! The server quit without updating PID file (/usr/local/mysql/data/KylinV10SP3.pid).

缺失了pid-file配置

在vim /etc/my.cnf增加相关配置

pid-file=/usr/local/mysql/mysqld.pid

创建 mysqld.pid文件

 touch mysqld.pid
