我整天都在做这件事,我需要一些帮助。
我正在尝试为我正在从 github 处理的 RoR 项目设置 mysql 数据库。
当我尝试在终端中设置数据库时,出现以下错误:
Eric-MacBook:~ eric$ cd ~/review_rocket
Eric-MacBook:review_rocket eric$ rake db:setup
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'
我浏览了关于 SO 的 20 个问题,但没有一个能够帮助我解决我的问题。
数据库已启动并正在运行,并且 database.yml 也已设置。
我现在有点生气......请......帮助......在为时已晚之前。
更新:我刚刚查看了我安装的 gem,并且由于某种原因它正在显示mysql2
(见下文)
Eric-Reas-MacBook:~ ericrea$ gem list
*** LOCAL GEMS ***
multi_json (1.8.2)
mysql2 (0.3.13)
net-sftp (2.1.2)
这对我来说似乎有点奇怪......
更新:这是我的 database.yml 的样子:
common: &common
adapter: mysql2
encoding: utf8
reconnect: false
pool: 5
user_name: xxxx
password: xxxx
socket: /var/run/mysqld/mysqld.sock
development:
<<: *common
database: dev_review_rocket
# Warning: The database defined as "money_tracker_test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *common
database: test_review_rocket
production:
<<: *common
database: prod_review_rocket
更新:现在尝试使用自制软件重新安装 mysql 时出现奇怪的错误(见下文):

Warning: mysql post_install failed. Rerun with `brew postinstall mysql`.
==> Caveats
A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.
To connect:
mysql -uroot
To have launchd start mysql at login:
ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
Then to load mysql now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Or, if you don't want/need launchctl, you can just run:
mysql.server start
