bug的原因是在linux系统下,mysql的配置文件my.cnf的basedir不能使用软连接.
表象如下:
|
1
2
3
4
5
6
7
|
#cat /usr/local/mysql/my.cnf | grep basedir
basedir=
/usr/local/mysql
#ln -sf Percona-Server-5.6.34-rel79.1-Linux.x86_64.ssl101 mysql
#/usr/local/mysql/support-files/mysql.server start
Starting MySQL (Percona Server). mysqld_safe ld_preload libraries can only be loaded from
system directories (
/usr/lib64
,
/usr/lib
,
/usr/local/mysql/lib
)
ERROR! The server quit without updating PID
file
(
/usr/local/mysql/data/pidfile
.pid).
|
然后,把basedir的地址换成绝对路径
|
1

4
|
#cat /etc/my.cnf | grep basedir
basedir=
/mysql/Percona-Server-5
.6.34-rel79.1-Linux.x86_64.ssl101
#/usr/local/mysql/support-files/mysql.server start
Starting MySQL (Percona Server). SUCCESS!

就是这么回事.......
此bug存在于5.6.34(我用出问题的版本),还有5.7.15(bug提供者的版本),其实我个人感觉严格来说也不能算是bug吧,毕竟也没影响正常使用,如果是官方版本,也不会出现此类问题,因为不用创软连接.
