编译安装apache2.4

一、安装需知

  • centos7环境

  • apache有自己独立的接口库,可跨多个操作系统使用。APR:Apache portable Run-time libraries,Apache可移植运行库。

  • httpd安装包下载:官网

  • 编译安装,需要依赖关系

  • 创建apache专用账户

二、编译操作步骤

#依赖包下载:
[root@centos7 ~]#yum -y install gcc make pcre-devel openssl-devel expat-devel

#下载源代码并解压缩:
[root@centos7 ~]#wget https://downloads.apache.org//apr/apr-1.7.0.tar.bz2
[root@centos7 ~]#wget https://downloads.apache.org//apr/apr-util-1.6.1.tar.bz2
[root@centos7 ~]#wget https://downloads.apache.org//httpd/httpd-2.4.46.tar.bz2

[root@centos7 ~]#ls
httpd-2.4.46.tar.bz2,apr-1.7.0.tar.bz2,apr-util-1.6.1.tar.bz2

[root@centos7 ~]#tar xvf apr-1.7.0.tar.bz2
[root@centos7 ~]#tar xvf apr-util-1.6.1.tar.bz2
[root@centos7 ~]#tar xvf httpd-2.4.46.tar.bz2

#将apr和apr-util源码与httpd源码合并,同时编译安装,节约操作步骤
#注意,要放在httpd目录的srclib目录里,并改名
mv apr-1.7.0 httpd-2.4.46/srclib/apr
mv apr-util-1.6.1 httpd-2.4.46/srclib/apr-util

#编译安装
[root@centos7 ~]#cd /httpd-2.4.43
[root@centos7 ~]#./configure \
--prefix=/app/httpd24 \
--enable-so \
--enable-ssl \
--enable-cgi \
--enable-rewrite \
--with-zlib \
--with-pcre \
--with-included-apr \
--enable-modules=most \
--enable-mpms-shared=all \
--with-mpm=prefork

#执行编译安装
[root@centos7 ~]#make -j 2 && make install

三、编译后操作

  • Httpd编译过程:/app/httpd24/build/config.nice
  • 自带的服务控制脚本:/app/httpd24/bin/apachectl
#创建专用账户
[root@centos7 ~]# useradd -s /sbin/nologin -r apache

#启用账户,需要修改配置文件
[root@centos7 ~]# vim /app/httpd24/conf/http
...
user apche
group apache
...

#配置帮助文档
[root@centos7 ~]# vim /etc/man_db.conf
...
MANDATORY_MANPATH /app/httpd24/man
...

#配置环境变量,便于快捷启停服务,或者配置service unit文件,用systemctl守护进程控制(推荐),centos7以上支持
#选一种方式即可,启停的的方式不能混着用,不能用apachectl启动,然后systemctl停
[root@centos7 ~]# echo 'PATH=/app/httpd24/bin:$PATH' > /etc/profile.d/httpd24.sh
[root@centos7 ~]# apachectl start | stop

#设置开机启动
[root@centos7 ~]# echo '/app/httpd24/bin/apachectl start' > /etc/rc.d/rc.local
[root@centos7 ~]# chmod +x /etc/rc.d/rc.local

-------------------------------------------------------------------------------------------------
#以上编译安装完成

#下面是推荐配置service unit文件,用systemctl守护进程控制服务,centos7以上支持
#如果不确定格式,可参考yum安装httpd后的service文件
[root@centos7 ~]# vim /usr/lib/systemd/system/httpd24.service
[Unit]
Description=The Apache HTTP Server
After=network.target remote-fs.target nss-lookup.target
Documentation=man:httpd(8)
Documentation=man:apachectl(8)

[Service]
Type=forking
#EnvironmentFile=/etc/sysconfig/httpd
ExecStart=/app/httpd24/bin/apachectl start
#ExecStart=/app/httpd24/bin/httpd $OPTIONS -k start
ExecReload=/app/httpd24/bin/apachectl graceful
#ExecReload=/app/httpd24/bin/httpd $OPTIONS -k graceful
ExecStop=/app/httpd24/bin/apachectl stop
KillSignal=SIGCONT
PrivateTmp=true

[Install]
WantedBy=multi-user.target

四、创建启动脚本(CentOS 6 以前版本)

#自定义启动脚本(参考httpd-2.2的服务脚本)

[root@centos6 ~]# cp /etc/rc.d/init.d/httpd /etc/rc.d/init.d/httpd24
[root@centos6 ~]# vim /etc/rc.d/init.d/httpd24
apachectl=/app/httpd24/bin/apachectl
httpd=${HTTPD-/app/httpd24/bin/httpd}
pidfile=${PIDFILE-/app/httpd24/logs/httpd.pid}
lockfile=${LOCKFILE-/var/lock/subsys/httpd24}

[root@centos6 ~]# chkconfig –add httpd24
[root@centos6 ~]# chkconfig –list httpd24
