#Tools

Before begin javaweb develop , we should get the tools what we need first. The tools we need can be devide into two group . First is server the second is ide we decide to use. In this tutorial , you can learn how to establish Tomcat server in your mac , and how to use these tools with Intellj idea .

##1. Get the JDK

###JDK

Clicking the title ,and jumping to download site of jdk . Chose the one you want and download it . I introduce you to download the dmg file to install jdk as after completing the install , you will see the java preference is already show in your System Preference Setting . Just like the figure next .

It is convenient that you can do many things through java preference like auto-launch when your computer start.

After intall the dmg file , use “java -version” and “javac” command to test if you hava install it will .

If you want to know where is your jdk after install , use the command next.

/usr/libexec/java_home

After using this command , you can get the jdk path (which also the JAVA_HOME environment variables). You can also use this command to set the path in your ide what ever Eclipse or Intellj .

##2. Prepare the Server

###Tomcat

Clicking the title above and jumping to Official Website of Tomcat then chose the tomcat server you want to download. Then you have finished our first step . Download these files like the figure above. These include doc for Tomcat and Tomcat server.

Then move the tomcat server to “/usr/local” and try start server.

(You can find the mothed about how to start the server from next figure.)

If you successfully start the tomcat, just begin next step.

###MySql

Clicking the title above and jumping to Official Website of MySql then download the dmg file you need . I introduce dmg file , too. The reason just the same as the jdk.

In the first picture you can see the MySql preference , but for your convenient , I put it here too.

After download it you will hava to test it .

sudo /usr/local/mysql/support-files/mysql.server start

Please remember the “sudo” , it’s very important.

sudo /usr/local/mysql/support-files/mysql.server stop

Use the command above to stop mysql .

Here I can show you the path to mysql.server file.

If you face a error which say something about pid , which usually appear , you have to know the key always lies in you don’s the privilege. So , be sure you use the “sudo” or you already change to root .

After you see “SUCCESS” , we go next step.

Runing the command next :

/usr/local/mysql/bin/mysql

If you see

Access denied for user ‘Dantrsey’@’localhost’ (using password: NO)

use the “sudo” , and may be you need use the command downstairs :

/usr/local/mysql/bin/mysql -u root -p

then entry the default password which you get affter install the dmg. If you forget it , run the next command :

sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables

then run mysql and do as next :

UPDATE mysql.user SET authentication_string=PASSWORD('root') WHERE User='root';
FLUSH PRIVILEGES;

and reboot mysql , test it with :

show databases;

if you see:

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

entry :

SET PASSWORD = PASSWORD('root');

and you have made it .(~_~)
