|
||
```shell

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。
|
||
|
||
#安装依赖包
|
||
yum install libaio -y
|
||
#初始化数据库
|

mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

#### 管理MySQL_etc/init.d
|
||
|
||
```shell
|
||
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
|
||
|
||
```sql
|
||
GRANT ALL PRIVILEGES ON *.* TO ycharge@"%" IDENTIFIED BY "ycharge";
|
||
flush privileges;
|
||
```
