Linux上安装Apache服务器

http://httpd.apache.org/download.cgi

httpd-2.4.29.tar.gz

#创建httpd用户
groupadd httpd
useradd -g httpd -s /sbin/nologin -M httpd
 
tar zxvf httpd-2.4..tar.gz
cd httpd-2.4.
./configure --prefix =/usr/local/apache
make && make install

编译apache时可能会出错：
#./configure --prefix……检查编辑环境时出现：
checking for APR... no
configure: error: APR not found . Please read the documentation
解决办法：

安装 apr  apr-util  pcre

https://apr.apache.org/download.cgi

apr-1.6.3.tar.gz

./configure --prefix=/usr/local/apr
make && make install

apr-util-1.6.1.tar.gz

./configure --prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config
make && make install

编译apr-util时报错：make[1]: *** [xml/apr_xml.lo] Error 1

解决方法：yum -y install expat-devel

ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/

pcre-8.38.zip

./configure --prefix=/usr/local/pcre

make && make install

然后安装Apache：

./configure --prefix=/usr/local/apache/ --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre/
 
make && make install

make 时上面报错，尝试用 apr-1.5.2 版本

下载地址： http://archive.apache.org/dist/apr/

wget http://archive.apache.org/dist/apr/apr-1.5.2.tar.gz

wget http://archive.apache.org/dist/apr/apr-util-1.5.2.tar.gz

安装方法与上面 1.6版本一样，果然成功了。应该是 CentOS7 才支持 apr-1.6 版本。

安装完成后，切到安装目录，/usr/local/apache

# vim conf/httpd.conf　　#配置“Listen”和“ServerName”属性；

Listen 80

ServerName localhost

# ./bin/apachectl configtest

Syntax OK

# 启动httpd

/usr/local/apache/bin/apachectl start | stop | restart

或者：

cp /usr/local/apache/bin/apachectl /etc/init.d/httpd

/etc/init.d/httpd start
