The tangle of installing apache in linux is that installing apache in linux is a very simple process. Three commands can be done, jxvf decompression, make compilation, make install installation is OK. I did not expect that this process is still quite costly. It may be related to the environment. Let's talk about my environment first. --------------------------- Linux: cenos5.5 (verification 4.8 will also encounter the following problems) apache: httpd-2.4.1.tar.bz2 www.2cto.com ------------------------- [root @ localhost apache] # tar jxvf httpd-2.4.1.tar.bz2 // Unzip apache compressed package [root @ localhost apache] # cd httpd-2.4.1 // locate under the httpd-2.4.1 folder [root @ localhost httpd-2.4.1] # ls // view the contents under the display httpd-2.4.1 folder [root @ localhost httpd-2.4.1] #. /configure -- help | more // view the installation apache configuration parameters [root @ localhost httpd-2.4.1] #. /configure -- prefix =/usr/local/apache -- enable-so // configure the apache path, followed by the -- enable-so parameter to let the apache core load DSO [root @ localhost httpd-2.4.1] # make // compile apache
Error! Tip: configure: error: APR not found. Please read the documentation on the apache official website can be downloaded to the apr-1.4.6.tar.gz to solve the apr not found problem >>> APR and APR-UTIL: http://apr.apache.org/download.cgi [Root @ localhost apache] # tar-zxf apr-1.4.6.tar.gz [root @ localhost apache] # cd apr-1.4.6 [root @ localhost apr-1.4.6] #. /configure -- prefix =/usr/local/apr [root @ localhost apr-1.4.6] # make [root @ localhost apr-1.4.6] # make install www.2cto.com after installation is complete, compile apache [root @ localhost httpd-2.4.1] # make again error! Tip: configure: error: APR-util not found. Please read the documentation! Or the above apache official website address and then download the apr-util-1.4.1.tar.gz to solve the APR-util not found problem >>>> [root @ localhost apache] # tar-zxf apr-util-1.4.1.tar.gz [root @ localhost apache] # cd apr-util-1.4.1 [root @ localhost apr-util-1.4.1] #. /configure -- prefix =/usr/local/apr-util -- with-apr =/usr/local/apr/bin/apr-1-config [root @ localhost apr-util-1.4.1] # make [root @ localhost apr-util-1.4.1] # make install and then compile apache, an error occurred again! Tip: configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/ , I X! The associations between linux installation software can sometimes crash... /Configure still prompts APR-util not found, add -- with-apr =/usr/local/apr -- with-apr-util =/usr/local/apr-util, and then choose >>> [root @ localhost apache] #. /configure-help | grep pcre -- with-pcre = PATH Use external PCRE library: http://ftp.exim.llorien.org/pcre/
Download pcre-8.30.zip with a large number of list files. Generally, the browser has a search function. you can press ctrl + f to search and locate the file and download it. [Root @ localhost apache] # unzip-o pcre-8.30.zip [root @ localhost apache] # cd pcre-8.30 [root @ localhost pcre-8.30] #. /configure -- prefix =/usr/local/pcre [root @ localhost pcre-8.30] # make [root @ localhost pcre-8.30] # make install compile Apache www.2cto.com [root @ yahoo httpd-2.3.12-beta] #. /configure -- prefix =/usr/local/apache2 -- with-apr =/usr/local/apr -- with-apr-util =/usr/local/apr-util/note, the following parameters must be installed with apr and apr- The util path is consistent. [Root @ localhost httpd-2.4.1] # make [root @ localhost httpd-2.4.1] # make install this compilation installation should no longer report any errors. Haha !! Start apache [root @ localhost bin] # pwd/usr/local/apache/bin [root @ localhost bin] # apachectl stop [root @ localhost bin] # apachectl start check 80 whether the port is occupied [root @ localhost conf] # netstat-an | grep: 80 check if the apache startup service starts [root @ localhost bin] # ps-aux | grep httpdWarning: bad syntax, perhaps a bogu '-'?

Is the port occupied? Modify the apache configuration file/usr/local/apache/conf/httpd. conf configuration file [root @ localhost conf] vi httpd. find the following line in the conf file: Change Listen 80 to another port, for example, 8080 or 8800. Find the following line: change ServerName www.example.com: 80 to the ip address of the local machine and add the port number, for example, change 192.168.0.105: Port 80 to correct it. the error is always reported. Since I have no experience installing apache in linux, I want to find out which page apache runs by default. So I found the file.../apache/htdocs/index.html (misled by tomcat )! Otherwise, the file You don't have permission to access/index.html on this server in the/var/www/html directory is actually running. Because I have insufficient file permissions. Add a permission to the file! Create a file index.html in/var/www/html [root @ localhost html] # chmod 766 index.html OK! Apache is available. the page is opened normally! The process is tangled and the ending is wonderful! Www.2cto.com ----------- summary --------------
