启动Tomcat
(使用eclipse
搭建java
web编程环境时，不需要启动Tomcat，eclipse运行程序时，会自己启动Tomcat。所以，作为系统服务启动Tomcat是为了讲系统作为web服务器，对外提供web服务，而不是启动之后，eclipse才能够链接到服务器。这一点和程序链接mysql服务器的概念截然不同。）

安装MySQL
终端输入命令：
.$ sudo apt-get
install mysql-server
这种方法安装完mysql需要修改root密码，不然会出现这么一种情况.'Access
denied for user 'root'@'localhost' (using password:
YES)'或者其他致使无法登录mysql的情况。可以按如下步骤解决：
1.打开/etc/mysql/debian.cnf文件，里面存储了相关的密码
sudo
gedit /etc/mysql/debian.cnf
在[client]段有user=以及password=这两行，此即我们需要的东西
2.输入命令:mysql
-udebian-sys-maint -p
debian-sys-maint即debian.cnf中user=后面的内容
回车后会提示输入密码，此时把password=后面的内容复制粘贴后回车即可进行mysql控制台(一般不要照打，容易出错，复制即可)
3.进入控制台后.按以下步骤进行：
use
mysql;
update
user set password=PASSWORD('新密码')
where user='root';
FLUSH
PRIVILEGES;
此时可以输入quit;退出后用root帐号登录，也可以继续其他操作。
MySQL编码设置
启动和停止服务器：.$
/etc/init.d/mysql start(stop)
主要配置文件所在位置：/etc/mysql/my.cnf
放置数据库表文件夹，相当于windows下mysql的date文件夹：/var/lib/mysql/
登录mysql后执行:>show
variables like 'character%';
修改/etc/mysql/my.cnf文件：
在[client]下面添加:
default-character-set=utf8
在[mysqld]下慢添加:
default-character-set=utf8
init_connect='SET
NAMES utf8'
修改好后，重启mysql即可，查询一下:>show
variables like 'character%';
重新启动mysql服务：.$
/etc/init.d/mysql start(stop)
