编译安装apache2.4.12
1.准备工作
操作系统 RHEL 6.7
YUM 本地yum源
IP地址 192.168.10.10
准备好，apache包和其他依赖安装包，本案例tar安装包下载目录在/install
#cd /install
用 wget从互联网下载安装包
#wget http://archive.apache.org/dist/apr/apr-1.4.5.tar.gz
#wget http://archive.apache.org/dist/apr/apr-util-1.3.12.tar.gz
#wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.10/pcre-8.10.zip
#wget http://archive.apache.org/dist/httpd/httpd-2.4.12.tar.gz
下载完成后，查看下载的文件，一共四个package
# ls -al
-rw-r--r-- 1 root root 994320 Feb 14 2012 apr-1.4.5.tar.gz
-rw-r--r-- 1 root root 769076 May 21 2011 apr-util-1.3.12.tar.gz
-rw-r--r-- 1 root root 6853506 Jan 28 2015 httpd-2.4.12.tar.gz
-rw-r--r-- 1 root root 1409751 Jun 26 2010 pcre-8.10.zip
安装apache 2.4.12首先需要安装依赖包，否则在进行configure处理apache的时候会出现以下错误，报APR版本过低，如下：
# ./configure --prefix=/usr/local/apache2 --enable-rewrite --enable-so --enable-headers --enable-expires --with-mpm=worker --enable-modules=most --enable-deflate
checking for chosen layout... Apache
checking for working mkdir -p... yes
checking for grep that handles long lines and -e... /bin/grep
checking for egrep... /bin/grep -E
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
configure:
configure: Configuring Apache Portable Runtime library...
configure:
checking for APR... configure: WARNING: APR version 1.4.0 or later is required, found 1.3.9
configure: WARNING: skipped APR at apr-1-config, version not acceptable
no
configure: error: APR not found. Please read the documentation.
2.删除旧的依赖包
删除旧版本的APR和自带的httpd
2.1 查询系统自带rpm包
# rpm -qa | grep apr
apr-util-devel-1.3.9-3.el6_0.1.x86_64
apr-1.3.9-5.el6_2.x86_64
apr-util-1.3.9-3.el6_0.1.x86_64
apr-util-ldap-1.3.9-3.el6_0.1.x86_64
apr-devel-1.3.9-5.el6_2.x86_64
# rpm -qa | grep httpd
httpd-tools-2.2.15-45.el6.x86_64
httpd-2.2.15-45.el6.x86_64
httpd-devel-2.2.15-45.el6.x86_64
删除1.3.9的APR，同种方法删除自带的HTTPD
# rpm -e --nodeps apr-1.3.9-5.el6_2.x86_64
# rpm -e --nodeps apr-util-1.3.9-3.el6_0.1.x86_64
# rpm -e --nodeps apr-devel-1.3.9-5.el6_2.x86_64
# rpm -e apr-util-ldap-1.3.9-3.el6_0.1.x86_64
# rpm -e apr-util-devel-1.3.9-3.el6_0.1.x86_64
删除完成后再次使用rpm -qa 进行查询，无输出则删除成功
3.安装依赖包
3.1 安装apr
解压apr包，然后进入解压目录,进行编译安装，其他同理
#tar -zxf apr-1.4.5.tar.gz
# cd apr-1.4.5
# ./configure --prefix=/usr/local/apr
#make && make install
make install 无报错完成后，查看apr版本
#cd /usr/local/apr/bin
#./apr-1-config --version
1.4.5 #当前版本为1.4.5
3.2 安装apr-util
解压安装 apr-util
# tar zxvf apr-util-1.3.12.tar.gz
进入加压目录，./congifure 编译安装
#cd apr-util-1.3.12
#./configure --prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config
#make && make install
3.3 安装 pcre
#unzip -o pcre-8.10.zip
#cd pcre-8.10
#./configure --prefix=/usr/local/pcre
#make && make instal
3.4 安装apache
#tar zxvf httpd-2.4.12.tar.gz
进入安装目录
#cd httpd-2.4.12
#./configure --prefix=/usr/local/apache2 --enable-rewrite --enable-so --enable-headers --enable-expires --with-mpm=worker --enable-modules=most --enable-deflate
#make && make install
安装完成后，检查版本
# /etc/init.d/httpd -version
Server version: Apache/2.4.12 (Unix)
Server built: May 27 2016 14:05:45
查看安装后的目录，如下:
# tree -L 1 /usr/local/apache2/
/usr/local/apache2/
├── bin
├── build
├── cgi-bin
├── conf
├── error
├── htdocs
├── icons
├── include
├── logs
├── man
├── manual
└── modules
注:如果没有tree 命令，用本地的yum 安装一下即可
#yum install -y tree
4.启动 apache
将apache的启动脚本复制到/etc/rc.d/init.d目录下
#cp /usr/local/apache2/bin/apachectl /etc/init.d/httpd
启动 apache
# /etc/init.d/httpd start
查看启动状态
# ps -ef | grep httpd
root 3334 1 0 19:51 ? 00:00:00 /usr/local/apache2/bin/httpd -k start
daemon 3335 3334 0 19:51 ? 00:00:00 /usr/local/apache2/bin/httpd -k start
daemon 3336 3334 0 19:51 ? 00:00:00 /usr/local/apache2/bin/httpd -k start
daemon 3337 3334 0 19:51 ? 00:00:00 /usr/local/apache2/bin/httpd -k start
daemon 3338 3334 0 19:51 ? 00:00:00 /usr/local/apache2/bin/httpd -k start
root 5465 2595 0 23:09 pts/0 00:00:00 grep httpd
使用浏览器输入 http://192.168.10.10
显示
It Works!
表示已经启动成功
5. 启动脚本
启动脚本给出了启动命令的用法，从apache启动脚本看，apache启动是调用/usr/local/apache2/bin/httpd，
$HTTPD -k $ARGV 启动是调用HTTPD='/usr/local/apache2/bin/httpd'
# cat /etc/init.d/httpd|grep -v ^#|grep -v ^$
ACMD="$1"
ARGV="$@"
HTTPD='/usr/local/apache2/bin/httpd'
if test -f /usr/local/apache2/bin/envvars; then
. /usr/local/apache2/bin/envvars
fi
LYNX="lynx -dump"
STATUSURL="http://localhost:80/server-status"
ULIMIT_MAX_FILES="ulimit -S -n `ulimit -H -n`"
if [ "x$ULIMIT_MAX_FILES" != "x" ] ; then
$ULIMIT_MAX_FILES
fi
ERROR=0
if [ "x$ARGV" = "x" ] ; then
ARGV="-h"
fi
case $ACMD in

$HTTPD -k $ARGV
ERROR=$?
;;

echo The startssl option is no longer supported.
