# # thus it can be seen that version 2.2.27 is missing. But the version of apache is still there.

[root@LAMP extra] #

The above method can only change the version number, but cannot change the version. If you need to change the version, Apache is installed by default. If it is compiled and installed, you can also modify the source code compilation method:

Modify the contents of the following two files:

/ home/lvnian/tools/httpd-2.2.27/include/ap_release.h

/ home/lvnian/tools/httpd-2.2.27/os/unix/os.h

Cp / home/lvnian/tools/httpd-2.2.27/include/ap_release.h / home/lvnian/tools/httpd-2.2.27/include/ap_release.h.ori

Cp / home/lvnian/tools/httpd-2.2.27/os/unix/os.h / home/lvnian/tools/httpd-2.2.27/os/unix/os.h.ori

The modifications are as follows:

#

40 # define AP_SERVER_BASEVENDOR "Apache Software Foundation"

41 # define AP_SERVER_BASEPROJECT "Apache HTTP Server"

42 # define AP_SERVER_BASEPRODUCT "Apache"

forty-three

44 # define AP_SERVER_MAJORVERSION_NUMBER 2

45 # define AP_SERVER_MINORVERSION_NUMBER 2

46 # define AP_SERVER_PATCHLEVEL_NUMBER 27

47 # define AP_SERVER_DEVBUILD_BOOLEAN 0

Modify it to the following

40 # define AP_SERVER_BASEVENDOR "lvnian IIS6 Software Foundation"

41 # define AP_SERVER_BASEPROJECT "lvnian IIS6 HTTP Server"

42 # define AP_SERVER_BASEPRODUCT "lvnian IIS6"

forty-three

44 # define AP_SERVER_MAJORVERSION_NUMBER 1

45 # define AP_SERVER_MINORVERSION_NUMBER 3

46 # define AP_SERVER_PATCHLEVEL_NUMBER 5

47 # define AP_SERVER_DEVBUILD_BOOLEAN 7

# # 3

Modify it with sed as follows:

Grep-n'"Apache' / home/lvnian/tools/httpd-2.2.27/include/ap_release.h

Cd / home/lvnian/tools/httpd-2.2.27/include/

Sed-I's / "Apache/" lvnian IIS6/g' ap_release.h

Sed-n'40 42p 'ap_release.h

Sed-n '44.47p' ap_release.h

Sed-n '44.47p' ap_release.h

Sed-n '3947p' ap_release.h

# sed command procedure

# define AP_SERVER_MAJORVERSION_NUMBER 1

# define AP_SERVER_MINORVERSION_NUMBER 3

# define AP_SERVER_PATCHLEVEL_NUMBER 5

# define AP_SERVER_DEVBUILD_BOOLEAN 7

# 3

Modify the following contents of the / home/lvnian/tools/httpd-2.2.27/os/unix/os.h file to what you want to modify

35 # define PLATFORM "Unix"

If it is modified to

# define PLATFORM "win32"

The sed command is as follows

Cd / home/lvnian/tools/httpd-2.2.27/os/unix/

Sed-n'/ # define PLATFORM / p 'os.h

Sed-I 's/#define PLATFORM "Unix" / # define PLATFORM "LVNIAN WIN" / g' os.h

Sed-n'/ # define PLATFORM / p 'os.h

#

[root@LAMP unix] # sed-n'/ # define PLATFORM / p 'os.h

# define PLATFORM "Unix"

[root@LAMP unix] # sed-I 's/#define PLATFORM "Unix" / # define PLATFORM "LVNIAN WIN" / g' os.h

[root@LAMP unix] # sed-n'/ # define PLATFORM / p 'os.h

# define PLATFORM "LVNIAN WIN"

[root@LAMP unix] #

Remember that you don't need to remove # logout if you want any of the above.
