在 Mac 上配置 InnoDB for MySQL 数据库答案

【问题描述】：

我正在配置 Mac 10.6 服务器，但在配置 MySQL 以支持 InnoDB 时遇到问题。

我的原始 my.cnf 文件启动并运行 MySQL 时没有问题。这里是：

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

但是，当我添加它以支持 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/ 存在并且具有正确的权限。我不确定如何对 mysql 进行故障排除以了解导致问题的原因。

MySQL 位于 /usr/local/ ： lrwxr-xr-x 1 根轮 24 Aug 26 12:17 mysql -> mysql-5.5.15-osx10.6-x86 drwxr-xr-x 16根轮544 7月13日16:26 mysql-5.5.15-osx10.6-x86

非常感谢您的帮助。

我不知道如何阅读。你能帮忙吗？

【问题讨论】：

我将 mysql 日志文件的输出添加到我原来的问题中。

标签： mysql innodb

【解决方案1】：

您的 mysql 错误日志文件中有什么内容？这通常会告诉你为什么 mysql 不会启动。如果你不知道你的日志文件在哪里，在 mysql 中运行这个命令：

show variables like "%log_error%";

您可以跟踪该文件以查看错误所在。当然，你需要关闭 Innodb 支持，这样你才能启动 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。
