lnmp 1.3 下。不管是将 mysql 的 4G 的那个文件还是 1-2G 的.cnf 文件 CP 到 /etc 目录下。mysql 重启就启动不了。换回装完 LNMP 的 my.cnf 就好使。

配置文件里涉及到目录， log 文件大小之类的参数，不是说改就能改的

@fei31976 对比了。。装完 LNMP 的 my.cnf 和 4G 的那个 my.cnf
在 4G 的 my.cnf 里没有如下内容。。。。。。。。。。。。。。。。。。装完 LNMP 的 my.cnf 里确有。
datadir = /usr/local/mysql/var
innodb_data_home_dir = /usr/local/mysql/var

在启动不成功时。看日志。确没有启动不成的日志。日志里只有启动成功的日志记录。

最后用 FIND 命令在 /usr/local/mysql/data 里又找到了一个.err 文件。。这里面记录的是错误日志。
/var 下。。是安装后记录的日志文件。而将 my-innodb-heavy-4G.cnf 替换 /etc/my.cnf 后。错误日志就到了。/usr/local/mysql/data 里。。。。
日志是：
---------------------------------------

mysql-bin.index 文件有。。我设成 777 后也不行。
