Lion上的MySQL 5.5无法正常工作

Question

我已经通过Mac OS X 10.7上的磁盘映像安装了MySQL 5.5.我也加入/usr/local/mysql/bin了我的道路.bash_profile.

which mysql 回报 /usr/local/mysql/bin/mysql

但是,无论我尝试什么,我似乎无法让服务器运行.

mysql -u root 收益:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

sudo /usr/local/mysql/bin/mysqld_safe 启动然后立即停止守护进程:

120130 23:18:57 mysqld_safe Logging to '/usr/local/mysql/data/Bryans-Macbook-Pro.local.err'.
120130 23:18:57 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
120130 23:18:59 mysqld_safe mysqld from pid file /usr/local/mysql/data/Bryans-Macbook-Pro.local.pid ended

我觉得我已经尝试了所有可能找到的解决方案,现在我已经没有想法了.我甚至尝试过安装旧版本的MySQL(5.1)并获得相同的结果和努力.

运行mysqld结果:

UPDATE

好吧,我从我的系统中完全删除了mysql,重新安装了旧版本(5.1),它现在实际上正在启动.但是,我仍然无法运行rails server.我收到以下错误:

/Users/bricker/.rvm/gems/ruby-1.8.7-p352/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle: dlopen(/Users/bricker/.rvm/gems/ruby-1.8.7-p352/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle, 9): Library not loaded: /opt/local/lib/mysql5/mysql/libmysqlclient_r.16.dylib (LoadError)

所以,我运行了这个命令:

sudo install_name_tool -change libmysqlclient_r.16.dylib /opt/local/lib/mysql5/mysql/libmysqlclient_r.16.dylib ~/.rvm/gems/ruby-1.8.7-p352/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle

但在尝试启动'rails服务器'时仍然收到错误.

更新2

好的,最后更新:在所有事情之后,多次重新安装mysql,看到所有这些错误 - 事实证明,原来的问题可能是宝石mysql2-0.2.7和之间的冲突mysql2-0.3.11.最终解决问题:

1. 从我的系统中删除了所有与mysql相关的文件(参见下面的bash脚本)

2. 从MySQL网站上提供的磁盘映像安装MySQL 5.1.61(64位)

3. 如下几行:

sudo install_name_tool -change libmysqlclient_r.16.dylib /opt/local/lib/mysql5/mysql/libmysqlclient_r.16.dylib ~/.rvm/gems/ruby-1.8.7-p352/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle

sudo install_name_tool -change libmysqlclient.16.dylib /usr/local/mysql/lib/libmysqlclient.16.dylib ~/.rvm/gems/ruby-1.8.7-p352/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle

1. 运行gem uninstall mysql2,并选择版本0.3.11- 此RVM部分上剩下的唯一版本是mysql2-0.2.7.

现在一切似乎都在运作!再次感谢所有的帮助.

Bash脚本从Mac OS X(10.6和10.7)中删除与mysql相关的文件.

#!/bin/bash
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
sudo rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /var/db/receipts/com.mysql.*
echo "Done."

复制到remove-mysql.sh,使其成为可执行文件(chmod +x remove-mysql.sh),然后运行它.

Answer 1

1. 跑步mysql_upgrade
2. skip-locking从以下位置删除选项my.cnf：MySQL - my.cnf 中的跳过锁定有何作用？

skip-locking如果你在你的 中找不到my.cnf，这意味着 MySQL 从与你期望不同的路径加载它。仔细检查一下。

PS 看来你是从旧版本升级了MySQL，不是吗？
