虚拟机下安装mysql的错误？
本帖最后由 wang509020 于 2016-01-11 15:07 编辑配置是这样的：
#cd /usr/local/src
#wget http://cdn.mysql.com//Downloads/MySQL-5.5/mysql-5.5.47-linux2.6-i686.tar.gz
#tar -zxvf mysql-5.5.47-linux2.6-i686.tar.gz
#mv mysql-5.5.47 /usr/local/mysql
#cd /usr/local/mysql
#mkdir -p /data/mysql
#./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
#echo $?
#useradd -s /sbin/nologin mysql
#chown -R mysql:mysql /data/mysql
#cp support-files/my-large.cnf /etc/my.cnf
#cp support-files/mysql.server /etc/init.d/mysqld
#vi /etc/init.d/mysqld
datadir=/data/mysql #修改数据存放位置
#chkconfig--add mysqld
#chkconfig mysqld on
#service mysqld start
到了这一步就出现如下错误：
160111 13:51:45 mysqld_safe Starting mysqld daemon with databases from /data/mysql
160111 13:51:45 'THREAD_CONCURRENCY' is deprecated and will be removed in a future release.

请高手分析一下，搞不太懂。 高手请帮忙看一下，这个是什么问题，感谢。 chown -R mysql:mysql /usr/local/mysql /data/mysql
