mysql 启动MySQL server PID file could not be found!

lwj1435 发表于 2016-3-9 10:42:30

* MySQL server PID file could not be found!
Starting MySQL
... * The server quit without updating PID file (/usr/local/mysql/var/iZ28ll5pvsxZ.pid).

我修改了
chmod -R 755 /usr/local/mysql/
还是重启后报这个错

你自己修改过数据库目录吗？默认目录是在 /usr/local/mysql/var/ 下面

按你上面发的错误信息是权限问题或文件被删除

一般只需要chown mysql:mysql 数据库目录，不要chmod

etc/init.d/mysql里面写的是：
# Set some defaults
mysqld_pid_file_path=
if test -z "$basedir"
then
basedir=/usr/local/mysql
bindir=/usr/local/mysql/bin
if test -z "$datadir"
then
datadir=/usr/local/mysql/data
fi
sbindir=/usr/local/mysql/bin
libexecdir=/usr/local/mysql/bin
else
bindir="$basedir/bin"
if test -z "$datadir"
then
datadir="$basedir/data"
fi
sbindir="$basedir/sbin"
libexecdir="$basedir/libexec"
fi

# datadir_set is used to determine if datadir was set (and so should be
# *not* set inside of the --basedir= handler.)
datadir_set=

是要改成var文件夹么?

lwj1435 发表于 2016-3-9 14:33:04

我改了还是报这个错！，我重装了也是这个错~

lwj1435 发表于 2016-3-9 14:36:12

也用了chown -Rf mysql:mysql还是没用，还是这个错误!

问题解决了，把原来的mysql停掉，再重新安装就可以了！
