准备三台主机

ip	name	服务
192.168.23.133	yc2	httpd
192.168.23.134	yc3	mysql
192.168.23.135	yc4	php

准备环境

三台主机都需配置,这里只举yc2的示例

//配置yum源

[root@yc2 ~]# curl -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
[root@yc2 ~]# sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
[root@yc2 ~]# sed -i 's|$releasever|8|' /etc/yum.repos.d/CentOS-Base.repo

//配置epel源

[root@yc2 ~]# yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm
[root@yc2 ~]# sed -i 's|^#baseurl=https://download.fedoraproject.org/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*
[root@yc2 ~]# sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*
[root@yc2 ~]# sed -i 's|$releasever|8|' /etc/yum.repos.d/epel*
[root@yc2 ~]# yum clean all
[root@yc2 ~]# yum makecache

//关闭防火墙和selinux

[root@yc2 ~]# systemctl stop firewalld
[root@yc2 ~]# setenforce 0

在yc2上安装httpd

//安装开发工具包
[root@yc2 ~]# yum -y groups mark install 'Development Tools'

//创建apache服务的用户和组
[root@yc2 ~]# useradd -r -M -s /sbin/nologin apache

//安装依赖包
[root@yc2 ~]# yum -y install bzip2 make openssl-devel pcre-devel expat-devel libtool gcc gcc-c++ libxml2-devel

//下载源码包
[root@yc2 ~]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/httpd/httpd-2.4.46.tar.bz2

[root@yc2 ~]# ls
anaconda-ks.cfg  apr-1.7.0.tar.gz  apr-util-1.6.1.tar.gz  httpd-2.4.46.tar.bz2

//安装apr
[root@yc2 ~]# tar xf apr-1.7.0.tar.gz
[root@yc2 ~]# cd apr-1.7.0
[root@yc2 apr-1.7.0]# vim configure
    cfgfile=${ofile}T
    trap "$RM "$cfgfile"; exit 1" 1 2 15
    # $RM "$cfgfile"		//过滤到该位置，将此行加上注释，或者删除此行
[root@yc2 apr-1.7.0]# ./configure --prefix=/usr/local/apr
[root@yc2 apr-1.7.0]# make
[root@yc2 apr-1.7.0]# make install

//安装apr-util

[root@yc2 ~]# tar xf apr-util-1.6.1.tar.gz 
[root@yc2 ~]# cd apr-util-1.6.1
[root@yc2 apr-util-1.6.1]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
[root@yc2 apr-util-1.6.1]# make
[root@yc2 apr-util-1.6.1]# make install

//安装httpd

[root@yc2 ~]# tar xf httpd-2.4.46.tar.bz2 
[root@yc2 ~]# cd httpd-2.4.46
[root@yc2 ~]# ./configure --prefix=/usr/local/apache   //写出下面的配置

--enable-modules=most 
--enable-mpms-shared=all 
--with-mpm=prefork
[root@yc2 ~]# make
[root@yc2 ~]# make install

//安装后配置

[root@yc2 ~]# echo 'export PATH=/usr/local/apache/bin:$PATH' > /etc/profile.d/httpd.sh
[root@yc2 ~]# source /etc/profile.d/httpd.sh
[root@yc2 ~]# which apachectl
/usr/local/apache/bin/apachectl
[root@yc2 ~]# ln -s /usr/local/apache/include/ /usr/include/httpd

//取消ServerName的注释
