pycharm连不上数据库:报警代码Connection to api@localhost failed. [08001] Could not create connection to d
pycharm 换成2019之后连接数据库用户名密码数据库名字都没错,就是连接不上去,网上百度一下,试试将URL后面拼接
?useSSL=false&serverTimezone=UTC
发现终于可以了 也连接上去了,但是每一次都要自己设置一下???
完美解决办法,新版的8.0版的mysql连接池应该是 以前的5.7版本是com.mysql.jdbc.Driver
试试更改时区时(往往问题都是出现在这)
a. 在终端里先使用管理员登录mysql,也就是root
mysql -uroot -p123
b. 输入命令
show variables like '%time_zone%'

c. Mysql默认为美国时间,我国时区要晚8小时,因此修改时间即可
set global time_zone = '+8:00' ;

d. 设置完以后,退出mysql,重新登录,检查时间是否被修改
结束后就退出cmd,去pycharm里面重新连接看看
所以,最好还是不要升级为新版本,因为说不定哪天就会蹦出一个新的bug让你措手不及
Django 连接mysql数据库
cmd中使用python3 manage.py migrate命令,报warn
WARNINGS:
?: (mysql.W002) MySQL Strict Mode is not set for database connection 'default'
HINT: MySQL's Strict Mode fixes many data integrity problems in MySQL, such as data truncation upon insertion, by escalating warnings into errors. It is strongly recommended you activate it. See: https://docs.djangoprojec
t.com/en/dev/ref/databases/#mysql-sql-mode
解决办法:settings.py文件夹加入DATABASES['OPTIONS']['init_command'] = "SET sql_mode='STRICT_TRANS_TABLES'"
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django_test',
'USER':'root',
'PASSWORD':'',
'HOST':'localhost',
'PORT':'3306',
#下面是新加入的
'OPTIONS':{
'init_command':"SET sql_mode='STRICT_TRANS_TABLES'",
'charset':'utf8mb4',
},
}
