contOS6.5 安装的系统是 Red hat(64 bit)Linux version 2.6.32-431.el6.x86_64 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) )

安装mysql数据库时报错：

Neither host 'localhost.localdomain' nor 'localhost' could be looked up with
/usr/local/mysql/bin/resolveip
Please configure the 'hostname' command to return a correct
hostname.
If you want to solve this at a later stage, restart this script
with the --force option

按提示应该是hosts里没有localhost，你可以看一下/etc/hosts是否有127.0.0.1 localhost.localdomain localhost
没有的话执行：echo "127.0.0.1 localhost.localdomain localhost" >> /etc/hosts
然后重启
卸载lnmp，再重新安装，不重新安装也行，在mysql源码目录里执行：

1. /usr/local/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/usr/local/mysql/var --user=mysql --force
   
2. chown -R mysql /usr/local/mysql/var
   
3. chgrp -R mysql /usr/local/mysql/.
   
4. \cp support-files/mysql.server /etc/init.d/mysql
   
5. chmod 755 /etc/init.d/mysql
