Apache 源码安装

Linux系统环境

[root@apache01 ~]#cat /etc/redhat-release                   #==》系统版本
CentOS release 6.7 (Final)
[root@apache01 ~]# uname –r                                 #==》内核版本
2.6.32-573.el6.x86_64
[root@apache01 ~]# uname -m                                 #==》系统架构

Apache配置文件
提示：/application/apache是Apache程序目录

/application/apache/conf/httpd.conf                   #==》Apache主配置文件httpd.conf
/application/apache/conf/extra/httpd-vhosts.conf      #==》Apache扩展的配置文件
/application/apache/bin/apachectl                     #==》Apache二进制启动命令

一、Apache功能

1、web服务（http 80）

二、Apache优点

1、配置简单，速度快，性能稳定可靠。

2、apache可做代理服务器、负载均衡、rewrite规则过滤等。

3、支持select模型

三、Apache常用命令
标注：假如nginx安装目录在/application/nginx

1、/application/apache2.4.38/bin/apachectl –t              #==》检查Apache配置文件语法

2、/application/apache/bin/apachectl start                 #==》启动Apache服务

3、/application/apache/bin/apachectl stop                 #==》停止Apache服务

4、/application/apache2.4.38/bin/apachectl graceful       #==》优雅重启Apache服务

5、/application/apache2.4.38/bin/apachectl -h             #==》查看帮助

四、Apache安装前准备工作

1、配置yum源（建议使用阿里云yum源mirrors.aliyun.com）

[root@apache01 ~]# yum repolist                 #==》检查yum源
[root@apache01 ~]#wget –O /etc/yum.repos.d/CentOS-Base.repo [http://mirrors.aliyun.com/repo/Centos-6.repo](http://mirrors.aliyun.com/repo/Centos-6.repo)         #==》配置yum源为阿里云
[root@apache01 ~]#wget -O /etc/yum.repos.d/epel.repo [http://mirrors.aliyun.com/repo/epel-6.repo](http://mirrors.aliyun.com/repo/epel-6.repo)         #==》配置yum源的epel扩展源为阿里云

2、安装Apache所需的lib库

[root@apache01 ~]# yum -y install zlib expat zlib-devel expat-devel openssl openssl-devel

3、源码安装apr软件包
标注：新版本Apache软件包无法支持低版本的apr软件包，yum无法安装最新版本apr软件包，只能下载原码最新版本手动编译安装

[root@apache01 ~]# mkdir -p /home/oldboy/tools/         #==》创建目录存放nginx软件包
[root@apache01 ~]# cd /home/oldboy/tools/
[root@apache01 tools]# wget http://mirrors.tuna.tsinghua.edu.cn/apache//apr/apr-1.7.0.tar.gz
[root@apache01 tools]# tar xf apr-1.7.0.tar.gz
[root@apache01 tools]# cd apr-1.7.0
[root@apache01 apr-1.7.0]# ./configure --prefix=/usr/local/apr
[root@apache01 apr-1.7.0]# make
[root@apache01 apr-1.7.0]# make install

4、源码安装apr-util软件包

[root@apache01 ~]#cd /home/oldboy/tools/ 
[root@apache01 tools]# wget http://mirrors.tuna.tsinghua.edu.cn/apache//apr/apr-util-1.6.1.tar.gz
[root@apache01 tools]# tar xf apr-util-1.6.1.tar.gz
[root@apache01 tools]# cd apr-util-1.6.1
[root@apache01 apr-util-1.6.1]# ./configure --prefix=/usr/local/apr_util  --with-apr=/usr/local/apr
[root@apache01 apr-util-1.6.1]# make
[root@apache01 apr-util-1.6.1]#make install

5、源码安装pcre软件包

[root@apache01 ~]#cd /home/oldboy/tools/
[root@apache01 tools]# wget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz
[root@apache01 tools]# tar xf pcre-8.40.tar.gz
[root@apache01 tools]# cd pcre-8.40
[root@apache01 pcre-8.40]# ./configure --prefix=/usr/local/pcre
[root@apache01 pcre-8.40]# make
[root@apache01 pcre-8.40]# make install

五、源码安装Apache

1、Apache官网下载Apache源码安装包到系统指定目录Apache官网地址http://www.apache.org/

[root@apache01 ~]# cd /home/oldboy/tools/
[root@apache01 tools]# wget http://mirror.bit.edu.cn/apache/httpd/httpd-2.4.38.tar.gz
[root@apache01 tools]# tar xf httpd-2.4.38.tar.gz
[root@apache01 tools]# ls
httpd-2.4.38 httpd-2.4.38.tar.gz
[root@apache01 httpd-2.4.38]# ./configure --prefix=/application/apache2.4.38/ --enable-deflate --enable-expires --enable-headers --enable-modules=most --enable-so --with-mpm=worker --enable-rewrite --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr_util --with-pcre=/usr/local/pcre/

[root@apache01 httpd-2.4.38]# echo $?

[root@apache01 ~]# ln -s /application/apache2.4.38/ /application/apache

六、启动Apache服务

[root@apache01 ~]# /application/apache/bin/apachectl start #==》启动提示如下错误
AH00557: httpd: apr_sockaddr_info_get() failed for apache01
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message

解决办法：
[root@apache01 ~]# vim /application/apache/conf/httpd.conf
# ServerName  [www.example.com:80](http://www.example.com:80)

修改成
ServerName localhost:80
[root@apache01 ~]# /application/apache/bin/apachectl -t
Syntax OK
[root@apache01 ~]# /application/apache/bin/apachectl start
[root@apache01 ~]# netstat -tlunp | grep 80
tcp 0 0 :::80 :::* LISTEN 46657/httpd
