Question

我正在配置Mac 10.6服务器，但我在配置MySQL以支持InnoDB方面遇到了麻烦。

MySQL启动并运行我的原始my.cnf文件没有问题。这是：

[mysqld]
#Don't resolve hostnames. All hostnames are IP's or 'localhost'.
skip-name-resolve
#Don't give threads different priorities.
skip-thread-priority

然而，当我添加它来支持InnoDB时，MySQL将无法启动。

[mysqld]
#Don't resolve hostnames. All hostnames are IP's or 'localhost'.
skip-name-resolve
#Don't give threads different priorities.
skip-thread-priority
# Uncomment the following if you are using InnoDB tables
innodb_data_home_dir=/var/mysql/
innodb_data_file_path=ibdata1:2000M;ibdata2:10M:autoextend
innodb_log_group_home_dir=/var/mysql/
innodb_log_arch_dir=/var/mysql/ 
# You can set .._buffer_pool_size up to 50 - 80 % 
# of RAM but beware of setting memory usage too high
innodb_buffer_pool_size=384M
innodb_additional_mem_pool_size=20M
# Set .._log_file_size to 25 % of buffer pool size
innodb_log_file_size=100M
innodb_log_buffer_size=8M
innodb_flush_log_at_trx_commit=1
innodb_lock_wait_timeout=50

我确认/ var / mysql /存在且具有正确的权限。我不确定如何解决mysql问题以了解导致问题的原因。

MySQL位于/ usr / local /： lrwxr-xr-x 1根轮24 8月26日12:17 mysql - ＆gt;的mysql-5.5.15-osx10.6-86 drwxr-xr-x 16根轮544 Jul 13 16:26 mysql-5.5.15-osx10.6-x86

非常感谢你的帮助。

我不知道怎么读这个。你能帮忙吗？

你的mysql错误日志文件中有什么？这通常会告诉你为什么mysql无法启动。如果您不知道日志文件的位置，请在mysql中运行以下命令：

show variables like "%log_error%";

您可以将该文件拖尾以查看错误。当然，您需要关闭Innodb支持，这样您就可以启动mysql来运行上面的命令。然后你可以关闭mysql，启用Innodb并尝试再次启动它。然后查看日志文件。
