1、採用命令 mysql_install_db –user=mysql 安裝時報錯
$ sudo ./scripts/mysql_install_db –user=mysql

FATAL ERROR: Neither host ‘liminpc’ nor ‘localhost’ could be looked up with
/usr/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

2.命令增加 –datadir=/usr/local/mysql/data，啟動成功

sudo ./scripts/mysql_install_db –user=mysql –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data –skip-name-resolve

**@****pc:/usr/local/mysql$ sudo ./scripts/mysql_install_db –user=mysql –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data –skip-name-resolve

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/local/mysql/bin/mysqladmin -u root password ‘new-password’
/usr/local/mysql/bin/mysqladmin -u root -h 192.168.1.159 password ‘new-password’

Alternatively you can run:

/usr/local/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd . ; /usr/local/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd mysql-test ; perl mysql-test-run.pl

WARNING: Found existing config file /usr/local/mysql/my.cnf on the system.
Because this file might be in use, it was not replaced,
but was used in bootstrap (unless you used –defaults-file)
and when you later start the server.
The new default config file was created as /usr/local/mysql/my-new.cnf,
please compare it with your file and take the changes you need.

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
–defaults-file argument to mysqld_safe when starting the server
