今天装apache，遇到好多坑，现在把它记下来，以免以后在犯错
首先先安装linux编译环境
首先下载三样东西
wget http://mirrors.hust.edu.cn/apache//httpd/httpd-2.4.25.tar.gz
wget http://apache.fayea.com//apr/apr-1.5.2.tar.gz
wget http://apache.fayea.com//apr/apr-util-1.5.4.tar.gz
然后安装编译环境
yum install gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel zlib-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel openssl-devel libxml2-devel gettext-devel pcre-devel
解压
tar xzvf httpd-2.4.25.tar.gz
tar xzvf apr-1.5.2.tar.gz
tar xzvf apr-util-1.5.4.tar.gz
然后编译
cd apr-1.5.2
./configure --prefix=/usr/local/apr
make && make install
cd apr-util-1.5.4
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make && make install
cd httpd-2.4.25
./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-modules=most --enable-mods-shared=most --enable-mpms-shared=most --with-mpm=event
make && make install
注意：如果这一步报错error: MPM most does not support dynamic loading.
就把
--enable-mpms-shared=most
改成--enable-mpms-shared=all
然后启动
先关掉防火墙
systemctl stop firewalld
在/usr/sbin/目录下
apachectl start
浏览器打开本地主机ip
