一、Apache安裝

1、安裝依賴包

#yum install -y pcre pcre-devel apr apr-devel zlib-devel gcc openssl-devel expat-devel

 

2、創建相應文件夾

#mkdir -pv /app/{httpd24,libmemcached,memcached,php}

#mkdir /root/src

#mkdir -pv /data/{www,logs}

 

3、下載apr和apr-util編譯安裝

#cd /src

#wget https://mirrors.aliyun.com/apache/apr/apr-1.6.3.tar.gz

#wget https://mirrors.aliyun.com/apache/apr/apr-util-1.6.1.tar.gz

#tar zxf apr-util-1.6.1.tar.gz

#tar zxf apr-1.6.3.tar.gz

 

#編譯安裝apr

#cd apr-1.6.3

#./configure --prefix=/usr/local/apr

#make && make install

 

#編譯安裝apr-util

#cd apr-util-1.6.1

#./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr

#make && make install

 

4、下載編譯安裝Apache2.4.34

#wget https://mirrors.aliyun.com/apache/httpd/httpd-2.4.34.tar.gz

#tar -zxf httpd-2.4.34.tar.gz

#cp -rf apr-1.6.3 httpd-2.4.34/srclib/apr

#cp -rf apr-util-1.6.1 httpd-2.4.34/srclib/apr-util

#cd httpd-2.4.34

#./configure --prefix=/app/httpd24 --enable-so --enable-ssl --enable-rewrite --with-zlib --with-pcre --with-included-apr --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork  --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/

#make

#make install

 

5、配置Apache

# echo "export PATH=$PATH:/app/httpd24/bin" > /etc/profile.d/httpd.sh

#source /etc/profile.d/httpd.sh

#cp /app/httpd24/bin/apachectl /etc/init.d/httpd

#chmod +x /etc/init.d/httpd

#vim /etc/init.d/httpd  #在第二行（#!/bin/sh）下面添加

#chkconfig: 2345 80 90

#description: Apache Web Server

#chkconfig --add httpd  #添加服務到chkconfig

#firewall-cmd --zone=public --add-port=80/tcp --permanent

 

#groupadd www && useradd -g www -s /sbin/nologin -M www

#chown -R www:www /app/httpd24/

#chown -R www:www /data/www/

 

6、配置httpd.conf

# vim /app/httpd24/conf/httpd.conf

LoadModule rewrite_module modules/mod_rewrite.s #去掉注釋，開啟偽靜態模塊

 

LoadModule php5_module modules/libphp5.so  #添加php庫

找到AddType application/x-gzip .gz .tgz添加如下兩行,讓Apache支持PHP擴展

AddType application/x-httpd-php  .php

AddType application/x-httpd-php-source  .phps

 

找到#ServerName www.example.com:80改成ServerName localhost #否則重啟會報錯httpd: Could not reliably determine the server's fully qualified domain name, using xxxx. Set the 'ServerName' directive globally to suppress this message

 

末尾添加，隱藏Apache版本號

ServerTokens ProductOnly

ServerSignature Off

 

更改用戶和組為www

User www

Group www

 

7、啟用虛擬機

注釋DocumentRoot "/app/httpd24/htdocs"

找到#Include /etc/httpd/extra/httpd-vhosts.conf

改成Include conf/vhost/*.conf

#mkdir /app/httpd24/conf/vhost

#vim /app/httpd24/conf/vhost/vhosts1.conf

<VirtualHost *:80>

ServerAdmin admin@admin.com

DocumentRoot "/data/www"

ServerName 192.168.10.80  #頂級域名

ServerAlias 192.168.10.80   #二級域名

ErrorLog "/data/logs/vhost1-error.log"

CustomLog "/data/logs/vhost1-access.log" combined

<Directory "/data/www">

#    SetOutputFilter DEFLATE

    Options FollowSymlinks #禁止目錄遍歷

    AllowOverride All     #支持偽靜態.htaccess

    Order allow,deny

    Allow from all

    DirectoryIndex  index.php index.html

    Require all granted

</Directory>

</VirtualHost>

#/etc/init.d/httpd restart

#部分依賴無法yum安裝需手動下載安裝

#wget https://mirrors.aliyun.com/epel/7/x86_64/Packages/l/libmcrypt-2.5.8-13.el7.x86_64.rpm

#https://mirrors.aliyun.com/epel/7/x86_64/Packages/l/libmcrypt-devel-2.5.8-13.el7.x86_64.rpm

#rpm -ivh libmcrypt-2.5.8-13.el7.x86_64.rpm  libmcrypt-devel-2.5.8-13.el7.x86_64.rpm

或者直接添加阿里云epel源：

#wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

然后再執行yum install libmcrypt-devel libmcrypt -y

 

2、下載并編譯安裝PHP
