CentOS7.6源码编译安装Apache

一、编译环境安装

  安装Apache之前，我们需要安装编译Apache和所依赖的一些软件包，其中有：gcc、gcc-c++、apr、apr-util、pcre等包。

  ① 安装gcc、gcc-c++编译环境

[root@localhost ~]# yum install gcc gcc-c++

  ② 安装apr-1.6.5依赖包

[root@localhost src]# wget https://downloads.apache.org/apr/apr-1.6.5.tar.gz    //下载压缩包
[root@localhost src]# tar -zxvf apr-1.6.5.tar.gz    //解压
[root@localhost src]# cd apr-1.6.5    //进入解压包目录下
[root@localhost apr-1.6.5]# ./configure --prefix=/usr/local/apr-1.6.5    //配置
...
config.status: executing libtool commands
rm: cannot remove 'libtoolT': No such file or directory
config.status: executing default commands    //配置过程报错
//解决方法：将configure文件中 RM='$RM' 修改为 RM='$RM -f'；
[root@localhost apr-1.6.5]# make clean    //清除之前产生配置文件
[root@localhost apr-1.6.5]# ./configure --prefix=/usr/local/apr-1.6.5    //再次配置即可成功
[root@localhost apr-1.6.5]# make && make install    //编译并安装

  ③ 安装apr-util-1.6.1依赖包

[root@localhost src]# wget https://downloads.apache.org/apr/apr-util-1.6.1.tar.gz    //下载压缩包
[root@localhost src]# tar -zxvf apr-util-1.6.1.tar.gz    //解压
[root@localhost src]# cd apr-util-1.6.1    //进入解压包目录下
[root@localhost apr-util-1.6.1]# ./configure --prefix=/usr/local/apr-util-1.6.1 --with-apr=/usr/local/apr-1.6.5/    //配置 apr-util需要和apr相关联
[root@localhost apr-util-1.6.1]# make && make install    //编译并安装
...
xml/apr_xml.c:35:19: 致命错误：expat.h：没有那个文件或目录    //编译过程报错
//解决方法：缺少expat库，执行命令yum install expat-devel -y即可；
[root@localhost apr-util-1.6.1]# make && make install    //再次编译并安装

  ④ 安装pcre-8.42依赖包

[root@localhost src]# wget https://ftp.pcre.org/pub/pcre/pcre-8.42.tar.gz    //下载压缩包
[root@localhost src]# tar -zxvf pcre-8.42.tar.gz    //解压
[root@localhost src]# cd pcre-8.42    ////进入解压包目录下
[root@localhost pcre-8.42]# ./configure --prefix=/usr/local/pcre-8.42
[root@localhost pcre-8.42]# make && make install    //编译并安装

二、安装Apache

[root@localhost src]# wget https://downloads.apache.org/httpd/httpd-2.4.41.tar.gz    //下载httpd-2.4.41.tar.gz至/usr/local/src/目录下
[root@localhost src]# tar -zxvf httpd-2.4.41.tar.gz    //解压
[root@localhost httpd-2.4.41]# ./configure --prefix=/usr/local/httpd-2.4.41 --with-apr=/usr/local/apr-1.6.5/ --with-apr-util=/usr/local/apr-util-1.6.1/ --with-pcre=/usr/local/pcre-8.42/    //配置 httpd需要和apr、apr-util、pcre相关联
[root@localhost httpd-2.4.41]# make && make install    //编译并安装

三、启动httpd服务

[root@localhost local]# /usr/local/httpd-2.4.41/bin/apachectl start    //启动服务
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message    //启动报错
[root@localhost local]# vim httpd-2.4.41/conf/httpd.conf    //解决方法：编辑httpd.conf文件，搜索"#ServerName"，添加ServerName localhost:80；
...
#ServerName www.example.com:80
ServerName localhost:80
...
[root@localhost local]# /usr/local/httpd-2.4.41/bin/apachectl restart    //重启服务

四、验证是否启动成功

• # netstat -tunl | grep 80 //查看80端口状态

tcp6       0      0 :::80                   :::*                    LISTEN

• # ps -ef | grep httpd //查看httpd进程

root     118816      1  0 21:20 ?        00:00:00 /usr/local/httpd-2.4.41/bin/httpd -k start
daemon   118938 118816  0 21:36 ?        00:00:00 /usr/local/httpd-2.4.41/bin/httpd -k start
daemon   118939 118816  0 21:36 ?        00:00:00 /usr/local/httpd-2.4.41/bin/httpd -k start
daemon   118940 118816  0 21:36 ?        00:00:00 /usr/local/httpd-2.4.41/bin/httpd -k start
root     119114   7439  0 21:45 pts/0    00:00:00 grep --color=auto httpd
