Apache(httpd) source installation

Because the Apr libraries used by httpd2.2 and httpd2.4 are different, and the Apr that comes with centos7 does not match them, you need to install the Apr library files using yum.

[root@dl-001 src]# WGet http://mirrors.cnnic.cn/apache/httpd/httpd-2.4.29.tar.gz //2.4 source package [root@dl-001 src]# WGet http://mirrors.cnnic.cn/apache/apr/apr-1.6.3.tar.gz //apr-1.6.3r package [root@dl-001 src]# WGet http://mirrors.cnnic.cn/apache/apr/apr-util-1.6.1.tar.gz //apr-util-1.6.1 package

Description: Download and unzip, the following operations need to enter.

1, Install the apr package

Note: APR version 1.6.2 has changed, encryption settings have been made, and the following commands are required for compilation (otherwise the library file cannot be invoked when Apache is installed):

[root@dl-001 httpd-2.4.29]# CC="gcc -m64" ./configure --prefix=/usr/local/apr

2, Install the Apr-util package

[root@dl-001 src]# cd apr-util-1.6.1 [root@dl-001 apr-util-1.6.1]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr [root@dl-001 apr-util-1.6.1]# echo $? 0 //Compile and install: [root@dl-001 apr-util-1.6.1]# make && make install

3, Install httpd

[root@dl-001 src]# cd httpd-2.4.29 [root@dl-001 httpd-2.4.29]# ./configure --prefix=/usr/local/apache2.4 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-so --enable-mods-shared=most //Report errors: configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/ //Note: The library file pcre needs to be installed //Solution: [root@dl-001 httpd-2.4.29]# yum list |grep pcre //View related packages //Install the following packages based on the results of your search: [root@dl-001 httpd-2.4.29]# yum install -y pcre-devel [root@dl-001 httpd--2.4.29]# ./configure --prefix=/usr/local/apache2.4 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-so --enable-mods-shared=most [root@dl-001 httpd-2.4.29]# echo $? 0 //Compile and Install [root@dl-001 httpd-2.4.29]# make [root@dl-001 httpd-2.4.29]# make install [root@dl-001 httpd-2.4.29]# echo $? 0

When source compilation installs httpd,. /configure executes without errors and errors occur when make

The errors are as follows:

... /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_StopParser' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_Parse' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_ErrorString' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_SetElementHandler' collect2: error: ld returned 1 exit status make[2]: *** [htpasswd] Error 1 make[2]: Leave Directory/usr/local/src/httpd-2.4.28/support" make[1]: *** [all-recursive] Error 1 make[1]: Leave Directory/usr/local/src/httpd-2.4.28/support" make: *** [all-recursive] Error 1

Note: The xml-related libraries are missing and the libxml2-devel package needs to be installed.Direct installation does not solve the problem because the apr-util called by httpd is already installed, but apr-util is not supported by the libxml2-devel package

1. Install the libxml2-devel package
[root@dl-001 ~]# yum install -y libxml2-devel

2. Remove the apr-util installation directory and recompile the installation

[root@dl-001 ~]# rm -rf /usr/local/apr-util [root@dl-001 ~]# cd /usr/local/src/apr-util-1.6.1 # This is an important step and you must clear the cache from the previous configuration [root@dl-001 apr-util-1.6.1]# make clean # Source Installation Three Steps [root@dl-001 apr-util-1.6.1]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr [root@dl-001 apr-util-1.6.1]# make [root@dl-001 apr-util-1.6.1]# make install

3. Recompile and install httpd

# It is also important to clean up the previous cache [root@dl-001 src]# cd /usr/local/src/httpd-2.4.28 [root@dl-001 httpd-2.4.29]# make clean [root@dl-001 httpd-2.4.29]# ./configure --prefix=/usr/local/apache2.4 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-so --enable-mods-shared=most [root@dl-001 httpd-2.4.29]# make # make did not report a mistake at this time [root@dl-001 httpd-2.4.29]# make install

4. Start the service

[root@dl-001 httpd-2.4.29]# Cd/usr/local/apache 2.4//Switch to the Apache 2.4 directory [root@dl-001 apache2.4]# ls bin build cgi-bin conf error htdocs icons include logs man manual modules //Note: More common directories are bin (executable file storage directory), conf (configuration file location directory), htdocs (storage of an access page), logs (log file storage directory), modules (storage of extensions). //View the modules that Apache loads: [root@dl-001 apache2.4]# /usr/local/apache2.4/bin/httpd -M //perhaps [root@dl-001 apache2.4]# /usr/local/apache2.4/bin/apachectl -M //Start: [root@dl-001 apache2.4]# /usr/local/apache2.4/bin/apachectl start AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using fe80::65d2:adc:20d3:8c74.
