Apache2.4.25編譯安裝之虛擬主機For Centos7

    安裝之前準備:

1. 配置好防火牆,selinux,時區.

2. 檢查系統是否安裝了httpd服務

3. yum install gcc gcc-c++ zlib-devel 

4. 下載軟件,pcre,apr,apr-util,apache
   

wget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz

wget http://mirror.bit.edu.cn/apache//apr/apr-1.5.2.tar.gz

wget http://mirror.bit.edu.cn/apache//apr/apr-util-1.5.4.tar.gz

wget http://apache.fayea.com/httpd/httpd-2.4.25.tar.gz

創建軟件安裝目錄及下載目錄

1.下載目錄: /opt/dowanload

2.安裝目錄:

[root@bbs ~]# tree -L 1 /opt/app/

/opt/app/                      #主目錄

├── apache -> /opt/app/apache2.4.25  #軟連接,方便以後升級及管理

├── apache2.4.25               #apache安裝目錄,所有文件存放地

├── apr                     #apr 目錄

├── apr-util                 #apr-util 目錄

└── pcre                    #pcre 目錄

編譯安裝依賴包

tar zxf apr apr-util pcre

先安裝apr,apr-util依賴apr

#cd /opt/download

#cd  apr-1.5.2

#./configure --prefix=/opt/app/apr

#make && make install

#cd apr-util-1.5.4

#./configure --prefix=/opt/app/apr-util --with-apr=/opt/app/apr

#make && make install 

#cd pcre-8.40

#./configure --prefix=opt/app/pcre

#make && make install

開始編譯安裝apache

# tar zxf  httpd-2.4.25.tar.gz

# cd http-2.4.25

# ./configure --prefix=/opt/app/apache2.4.25 --with-apr=/opt/app/apr --with-apr-util=/opt/app/apr-util --with-pcre=/opt/app/pcre --with-mpm=worker --enable-rewrite --enable-so --enable-headers --enable-expires --enable-deflate

# make && make install

虛擬主機篇(先備份好需要改動的配置文件)

#軟連接 ln -s /opt/app/apache2.4.25 /opt/app/apache

默認安裝完成後有如下文件:

編輯虛擬主機文檔,跟2.4版本前的稍微有些變動

[root@bbs extra]# egrep -v "^$|#"  /opt/app/apache/conf/extra/httpd-vhosts.conf

<VirtualHost *:80>                  

    ServerAdmin sadoc.blog.51cto.com      

    DocumentRoot "/var/www"             #web網站存放目錄,請mkdir好目錄

    ServerName bbs.52cto.com            #域名

    ServerAlias 52ctt.com              #域名別名

    ErrorLog "logs/bbs-error_log"         #錯誤日誌

    CustomLog "logs/bbs-access_log" common   #客戶端訪問日誌

</VirtualHost>

修改主配置文件

DocumentRoot "/opt/app/apache2.4.25/htdocs"

<Directory "/opt/app/apache2.4.25/htdocs">

    Options Indexes FollowSymLinks

    AllowOverride None

    Require all granted

</Directory>

#新增如下,不增加會報錯403錯誤.

<Directory "/var/www">

   Options Indexes FollowSymLinks

   AllowOverride None

   Require all granted

</Directory>

#取消了vhost的加載註釋

Include conf/extra/httpd-vhosts.conf

apache服務啓動方式:

[root@bbs ~]# /opt/app/apache/bin/apachectl -t  #檢查配置文件是否正常.

Syntax OK   

[root@bbs ~]# /opt/app/apache/bin/apachectl -k start  #啓動服務

自己手動寫啓動腳本,方便啓動.

腳本寫的很簡單,也可以用進程數量判斷

[root@bbs ~]# cat /etc/init.d/httpd 

#!/bin/bash

#author:http://sadoc.blog.51cto.com/

#2017-04-06

#加載函數庫

. /etc/rc.d/init.d/functions

#定義變量本腳本以Pid文件是否存在判斷啓動.

PID="/opt/app/apache/logs/httpd.pid"

STARTING="/opt/app/apache/bin/apachectl"

start(){

if [ ! -s "$PID" ];then

  $STARTING -k start

  action "Apache Start" /bin/true

fi

}

stop(){

if [ -s "$PID" ];then

  $STARTING -k stop

  action "Apache Stop:" /bin/true

fi

}

case "$1" in

start)

start

;;

stop)

  stop

  

  ;;

restart)

  $0 stop;

  $0 start;

  

  ;;

 

esac

# chmod +x /etc/init.d/httpd 

用了腳本後，直接yum方式啓動,centos7可以用systemctl管理啓動

[root@bbs ~]# systemctl status httpd.service
