centos7安裝mysql時，執行scripts/mysql_install_db --user=mysql報錯解決方案

當我們執行：

./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql

會出現：

Neither host 'xxx' nor 'localhost' could be looked up with
./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

這個問題是我們下載MYSQL安裝包的時候，我們下載的是32位的，而系統是64位的，所以纔會出現這個問題
