1、Ubuntu安装MySQL所需软件包
sudo apt-get install binutils cpp fetchmail flex gcc libarchive-zip-perl libc6-dev libcompress-zlib-perl libdb4.3-dev libpcre3 libpopt-dev lynx m4 make ncftp nmap perl perl-modules unzip zip zlib1g-dev autoconf automake1.9 libtool bison autotools-dev g++ build-essential
2、安装libncurses5-dev
sudo apt-get install libncurses5-dev
通过源码编译安装软件时，，出现错误信息：
checking for termcap functions library… configure: error: No curses/termcap library found
安装libncurses5-dev库方可解决。
3、安装MySQL
mysql使用utf-8作为默认编码：
groupadd mysql
useradd -g mysql mysql
tar -zxvf mysql-5.0.45.tar.gz
cd mysql-5.0.45
./configure –prefix=/usr/local/mysql –with-charset=utf8 –with-collation=utf8_general_ci –with-extra-charsets=latin1
make
make install
vi my.cnf
输入代码：
[client]
default-character-set = utf8
port = 3306
socket = /tmp/mysql.sock
[mysql]
prompt="(\u:Molutran's MySQL Server:)[\d]> "
no-auto-rehash
[mysqld]
#default-character-set = utf8

[mysqldump]
quick
max_allowed_packet = 32M
4、给MySQL安装目录加写权限并改变属组
chmod +w /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql
5、附带修改root用户密码
mysql>use mysql
mysql>UPDATE user SET password=PASSWORD('new_password') WHERE user='root';
mysql>FLUSH PRIVILEGES;
mysql>exit
