Mac build Java Environment (i)

First, Apache

The Mac comes with an Apache environment.

Open terminal, enter sudo apachectl-v, view Apache version.

Enter sudo apachectl start to start Apache. After startup, enter http://localhost in the browser to view the content as "IT work!" The page.

Open Finder,shift+command+g to the/,--> library-->webserver-->documents-->index.html.en You can modify the page content.

Apache under the/etc directory, etc is a hidden directory, shift+command+g to etc can be found, there are apache2 folder, content and window.

Set up a virtual host

1. Run "" In terminal sudo vi /etc/apache2/httpd.conf to open the Apche configuration file

2. Find "" In httpd.conf #Include /private/etc/apache2/extra/httpd-vhosts.conf , remove the previous "" ＃ , save and exit.

3. Run " sudo apachectl restart ", after restarting Apache, the virtual host configuration function is turned on.

4. Run " sudo vi /etc/apache2/extra/httpd-vhosts.conf ", the configuration virtual host file httpd-vhost.conf is opened and the virtual host is configured. It is important to note that the file is enabled by default for two virtual hosts as an example:

<VirtualHost*:80>ServerAdmin [email protected] documentroot "/usr/docs/dummy-host.example.com" ServerName dummy-host.example. COM errorlog "/private/var/log/apache2/dummy-host.example.com-error_log" Customlog "/private/var/log/apache2/ Dummy-host.example.com-access_log "Common</VirtualHost> <VirtualHost*:80>ServerAdmin [email protected] documentroot "/usr/docs/dummy-host2.example.com" ServerName Dummy-host2.exampl e.com errorlog "/private/var/log/apache2/dummy-host2.example.com-error_log" Customlog "/private/var/log/apache2/ Dummy-host2.example.com-access_log "Common</VirtualHost>

Code

　　

In fact, these two virtual hosts do not exist, and when no other virtual host is configured, it may result in the following prompt when accessing localhost:

ForbiddenYou don‘t have permission to access /index.php on this server

The simplest way to do this is to add the # to the front of each line and comment it out, so that you can refer to it without causing other problems.

5. Add the following configuration

<VirtualHost*:80>documentroot "/library/webserver/documents" ServerName localhost errorlog "/private/var/log/apache2/localhos T-error_log "Customlog"/private/var/log/apache2/localhost-access_log "Common</VirtualHost> <VirtualHost*:80>documentroot "/users/snandy/work" ServerName mysites errorlog "/private/var/log/apache2/sites-error_log" Customlog "/private/var/log/apache2/sites-access_log" Common<Directory/>Options Indexes followsymlinks multiviews allowoverride None Order deny, allow to from all</Directory></VirtualHost>

Code

Save the exit and restart Apache.

Second, Tomcat

The difference between Tomcat and Apache.

Apache is a Web server (static parsing, such as HTML), and Tomcat is a Java application server (dynamic parsing, such as JSP, PHP)

Tomcat is just a servlet (JSP also translated into a servlet) container that can be considered an Apache extension, but can be run independently of Apache

installation of Tomcat

1. Download Tomcat,

2. Unzip the compressed file into the Mac system: under the "/library" directory, rename the folder to Tomcat.

3. Modify file permissions: sudo chmod 755/library/tomcat/bin/*.sh

4. Execute the startup.sh under/library/tomcat/bin.

5. Set the manager's account number and password:
Edit "/library/tomcat/conf/tomcat-users.xml", join

<rolename= "Manager"/><username = "Tomcat" Password = "xxxx" Roles = "Manager" />

Code

6. Open http://localhost:8080
