安装`Mysql` `5.7`

yum install lrzsz -y
mkdir /usr/local -p
cd /usr/local
rz -be  选择 mysql-5.7.42-el7-x86_64.tar.gz
tar -zxf mysql-5.7.42-el7-x86_64.tar.gz
mv mysql-5.7.42-el7-x86_64 mysql
rm -rf mysql-5.7.42-el7-x86_64.tar.gz

vi /etc/profile
#添加如下内容
export PATH=/usr/local/mysql/bin:$PATH
#然后source生效
source /etc/profile

#添加用户并授权相关
useradd mysql
id mysql
mkdir /data/mysql -p
chown -R mysql:mysql /usr/local/mysql/*
chown -R mysql:mysql /data/*

其中：
/usr/local/mysql/是MySQL软件所在目录。
/data/mysql是将来存放MySQL数据的目录。

#初始化数据库
mysqld --initialize-insecure  --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql


#配置文件

vi /etc/my.cnf

[mysqld]
user=mysql
basedir=/usr/local/mysql
datadir=/data/mysql
server_id=1
port=22066
socket=/tmp/mysql.sock
[mysql]
socket=/tmp/mysql.sock

忽略大小写

lower_case_table_names=1

管理MySQL_etc/init.d

mkdir /etc/init.d -p
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

重定向文件

ln -s /usr/lib64/libncurses.so.6.2 /usr/lib64/libncurses.so.5
ln -s /usr/lib64/libtinfo.so.6.2 /usr/lib64/libtinfo.so.5

#启动、重启命令
service mysqld start
service mysqld restart

重置密码

/etc/init.d/mysqld stop

mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
mysql
update mysql.user set authentication_string=PASSWORD("DsideaL147258369") where user='root' and host='localhost';

flush privileges;

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY 'DsideaL147258369' WITH GRANT OPTION; 

flush privileges;
exit

/etc/init.d/mysqld restart
mysql -uroot -pDsideaL147258369

现在用Navicat Prenium就可以远程访问到数据库了。

YLT项目中使用的用户名：ycharge，密码：ycharge 需要创建
CREATE USER 'ycharge'@'%' IDENTIFIED BY 'ycharge';
GRANT all privileges ON yltcharge.* TO 'ycharge'@'%';
FLUSH PRIVILEGES;

创建使用账号

GRANT ALL PRIVILEGES ON *.* TO ycharge@"%" IDENTIFIED BY "ycharge";
flush privileges;
