Instructions:
I. First, Apache on Fedora. The date time stamp for each entry in a log is useful information when searching a log containing thousands of entries for entries that occurred at a certain time on a certain date. However, withFedora virtual machines, the odds of your date and time being accurate are small unless your machine is synchronized with an external time server. Therefore, the first thing we'll do in this lab is to synchronize your date and time with an ntp server.
1. Start this process by logging into your virtual machine as root and opening a command window. At the command prompt, type yum install -y ntp and press Enter. The yum installer will install the ntp daemon, and you will return to the command prompt.
2. Type ntpdate pool.ntp.org and press Enter. The ntp daemon will update your time and date.
3. To verify that the date and time are correct, type date at the command prompt. Record the date and time in the space provided.
II. There are many ways that you can locate the Apache log files. We'll examine one method.
1. At the command prompt, type
grepCustomLog /etc/httpd/conf/httpd.conf
grep will display several lines, one of which contains the relative path of the log file. Record the name and location of the Apache log file in the space provided. Note that line containing the name is the only line that doesn't start with a pound sign. Also, it is expressed as a relative path.
2. Locate the log file and record its absolute path in the space provided. Hint: You can use the locate or find commands to obtain the absolute path.
III. Now that we've found the log file, let's put something into it that we should recognize.
1. Switch to the graphical user interface for your Fedora machine, log in, and open Firefox. Type the following URL into the address text box and press Enter:
https://localhost
Summarize the web page that is displayed by your browser.
2. Switch back to the command window. At the command prompt, type
grepCustomLog /etc/httpd/conf/httpd.conf
Record the name and location of the Apache log file in the space provided. Note that this value is expressed as a relative path in the Apache configuration file.
3. Open the log file using vi and the absolute path you previously recorded. Scroll down to the last entry in the log and record that entry in the space provided.
4. Based on your reading assignment and any information you can find about the log on the Internet, describe the various parts of the entry you recorded and what they are used for.
5. Exit out of vi.
IV. Now we'll do the same thing with the error log file.
1. typegrepErrorLog /etc/httpd/conf/httpd.conf at the command prompt, and then press Enter.
Record the name and location of the Apache error log file in the space provided. Note that this value is expressed as a relative path in the Apache configuration file.
2. Locate the error log file and record its absolute path in the space provided. Hint: You can use the locate or find commands to obtain the absolute path.
3. Switch to the graphical user interface for your Fedora machine, and open Firefox. Type the following URL into the address text box and press Enter:
localhost/pagenothere.html
Summarize the error message that is reported by your browser.
4. Switch back to the command line and open the error log using vi and the path for the error log that you recorded above. Scroll to the last entry in the log and record it in the space provided.
5. Compare the information in the log with the error message displayed by the browser. Do they match?
V. Next, we'll examine how we view logging for IIS 7.
1. Start your Windows Server 2008 virtual machine, and log in as administrator.
2. Verify that the date and time for your machine is correct. Windows virtual machines are better about keeping time, so this should not be a problem.
3. Open your Web browser, type localhost in the address text box. and press Enter. The home page for your Web site will display in the browser.
4. Navigate to the IIS manager, open your Web site in the left-hand pane, and double click on it. The icons associated with the features and settings for your Web site will display in the right-hand pane.
5. Under the IIS section, click on the Logging icon to open it. The Logging page will display.
6. Examine the current settings for logging and record the location of the log files in the space provided.
7. Navigate to the location you previously recorded where the log files are stored. You will see several log files.
8. Open the most recent log file and scroll to the bottom. Record the line with the most recent date in the space provided.
9. Using your text book and sources from the Internet, research each field in the line and record what each represents in the space provided.
