Linux源代码编译安装详解

[日期:2018-12-02] 来源:Linux社区  作者:jzbgltb [字体: ]

1. 编译源代码步骤


configure、Makefile.in一般是项目管理器自动生成的,这依赖于两个开发工具:

  • autoconf:生成configure脚本文件;
    • autoconf需要结合一个配置文件来和其它命令生成configure脚本;这个配置文件告诉autoconf当前代码有哪些特性、指定哪些安装路径等,而后才能生成configure脚本;
  • automake:生成Makefile.in模板文件;
    • automake也要结合一个文件,这个指明有多少程序文件、它们的依赖关系是什么、以及使用哪一种版本的编译器等,而后才能生成Makefile.in;
Note:在安装之前查看INSTALL和README文件查看安装方法,因为不同程序包安装步骤不一样,有的程序包不需要configure,直接make后执行make install;而有的程序包不需要执行make install,只有一个二进制文件直接复制即可完成;

安装开发组件
想要进行编译,提前安装开发组件

CentOS 6:Development Tools、Server Platform Development
CentOS 7:Development Tools、Development and Creative Workstation

(1) ./configure(也可能是config文件)
--help:获取支持使用的选项;

在执行make命令之前,用户指定程序包的编译参数、启用特性、安装路径等等;
configure脚本会收集当前系统上的开发环境中所依赖各组件的版本、特性等,并检查所依赖的环境是否能满足,如果检查到所依赖的程序包不存在立即报错,无法执行下一步。最后会根据用户指定信息和Makefile.in文件生成一个makefile文件;

##通用的几个选项
--prefix=          :指定安装的路径
--sysconfdir=      :指定配置文件目录
--enable-feature   :启用某个特性
--disable-fecture  :禁用特性
--with-function    :启用某功能
--without-function :禁用某功能

(2) make

每个源代码都有专用的makefile,在make时依据这个配置文件,调用指定的预处理器做处理、调用指定的编译器做处理、编译文件的顺序等操作等;

(3) make install

其实是一些脚本,实现把构建出的应用程序,分别分配到用户指定的目录中;如创建出的二进制文件放到指定的二进制目录、库文件放到指定的库目录等等,使用install拷贝命令也能实现;

2. 安装后的配置

(1) 将二进制程序目录添加至PATH文件变量中,否则只能使用绝对路径才能运行程序

编辑文件/etc/profile.d/NAME.sh  
export PATH=/PATH/TO/BIN:$PATH

(2) 导出库文件路径

编辑/etc/ld.so.conf.d/NAME.conf,添加新的库文件所在的目录至此文件中;    
例如:/usr/local/apache2/lib   

ldconfig -v:重新加载库文件路径,并查看;
ldconfig -p:查看已加载所有库文件路径;

(3) 导出头文件

/usr/include/目录下,创建软链接; 
ln -s  target_dir  soft_link        ##可以导出一个目录为所有文件链接,也可以为每一个头文件导出一个链接,然后把创建的链接输出到/usr/include/目录下,或者直接复制头文件至/usr/include/目录;

(4) 导出man手册

Centos7是在/etc/man_db.conf的40到50行之间,添加一个MANPATH参数(Centos6可能是/etc/man.config);    
MANPATH_MAP     /usr/local/apache2/bin  /usr/local/apache2/man  

3. 编译安装实验

3.1. Centos7编译安装apache 2.2.27

系统版本与软件版本

[root@GNOME-C7 ~]# cat /etc/RedHat-release
CentOS Linux release 7.4.1708 (Core)
[root@GNOME-C7 ~]# uname -r
3.10.0-693.el7.x86_64
------------------------------------------------------------------
apr-1.6.3
apr-util-1.6.1
httpd-2.2.27

提前安装开发环境
[root@GNOME-C7 ~]# yum groupinstall -y "Development tools" "Development and Creative Workstation"

3.1.1. 安装apr-1.6.3

[root@GNOME-C7 ~]# cd apr-1.6.3/
root@GNOME-C7 apr-1.6.3]# ./configure -prefix=/usr/local/apr-1.6.3
[root@GNOME-C7 apr-1.6.3]# make
[root@GNOME-C7 apr-1.6.3]# make install

3.1.2. 安装apr-util-1.6.1

[root@GNOME-C7 apr-1.6.3]# cd ../apr-util-1.6.1/
[root@GNOME-C7 apr-util-1.6.1]# ./configure -prefix=/usr/local/apr-unil-1.6.1 --with-apr=/usr/local/apr-1.6.3

[root@GNOME-C7 apr-util-1.6.1]# make
遇到报错:
xml/apr_xml.c:35:19: fatal error: expat.h: No such file or directory
#include <expat.h>
                   ^
compilation terminated.
make[1]: *** [xml/apr_xml.lo] Error 1
make[1]: Leaving directory `/root/apr-util-1.6.1'
make: *** [all-recursive] Error 1
解决方法:yum install -y expat-devel

[root@GNOME-C7 apr-util-1.6.1]# make install

3.1.3. 安装httpd-2.2.27

编译安装

[root@GNOME-C7 apr-util-1.6.1]# cd ../httpd-2.2.27/
[root@GNOME-C7 httpd-2.2.27]# ./configure --sysconfdir=/etc/httpd --prefix=/usr/local/apache2  --with-apr=/usr/local/apr-1.6.3 --with-apr-util=/usr/local/apr-unil-1.6.3 --with-mpm=prefork --with-included-apr --enable-mods-shared=most --enable-ssl --enable-suexec --enable-so
遇到报错:configure: error: ...No recognized SSL/TLS toolkit detected
解决方法:yum install -y openssl-devel

[root@GNOME-C7 httpd-2.2.27]# make
[root@GNOME-C7 httpd-2.2.27]# make install

编译第二次,从而得到httpd.worker        ##这种方法不确定是否可以
[root@GNOME-C7 httpd-2.2.27]# cd ../
[root@GNOME-C7 ~]# rm -rf httpd-2.2.27/
[root@GNOME-C7 ~]# tar -xf httpd-2.2.27.tar.bz2
[root@GNOME-C7 ~]# cd ./httpd-2.2.27/
[root@GNOME-C7 httpd-2.2.27]# ./configure --sysconfdir=/etc/httpd --prefix=/usr/local/apache2  --with-apr=/usr/local/apr-1.6.3 --with-apr-util=/usr/local/apr-unil-1.6.3 --with-mpm=worker --with-included-apr --enable-mods-shared=most --enable-ssl --enable-suexec --enable-so
[root@GNOME-C7 httpd-2.2.27]# make       ##不用执行make install否则就会覆盖当前apache的文件了
[root@GNOME-C7 httpd-2.2.27]# cp ./httpd /usr/local/apache2/bin/httpd.worker


本次使用的编译参数
--prefix=/PATH:指明安装路径;
--sysconfdir=/PATH:指明配置文件路径;不指明,默认在安装路径下;
--enable-so:表示启用DSO动态模块加载机制;
--enable-ssl:启用支持ssl功能;
--enable-mods-shared=most:表示动态的编译进来大多数的模块;如果使用--enable-mods-shared=all,则指动态的编译所有的模块。
--with-apr=/PATH:指明apr程序包的路径;不使用=指明路径会在默认路径查找;
--with-apr-util=/PATH:指明apr-util程序包的路径;
--with-mpm=prefork:指明默认使用的MPM模块;


说明:
静态编译:将module直接在安装的过程中放到apache中,当apache使用module的时候,就可以直接使用了。
动态编译:将module引入到apache之中,在使用的时候才会真正的去加载(通过LoadModule命令)
--with.....:表示依赖的包,不指明路径,编译安装时会到默认路径下找;
--without.....:不依赖的包;
--enable.....:启用特性;
--disable.....:禁用特性;


可能用到的其他参数
[root@Centos7 httpd-2.2.29]# ./configure --help        ##查看有哪些支持的选项
部分内容如下:
    Fine tuning of the installation directories:
      --bindir=DIR            user executables [EPREFIX/bin]:所有用户执行的命令放在哪个目录;
      --sbindir=DIR           system admin executables [EPREFIX/sbin]:管理员执行的命令放在哪个目录;
      --libexecdir=DIR        program executables [EPREFIX/libexec]:库执行的程序放在哪个目录;

    libapr-1.so (libc6,x86-64) => /usr/local/apache2/lib/libapr-1.so

3.1.8. 创建服务管理脚本

这两个脚本是从其他机器上复制的,然后改了一下文件与目录的路径

[root@GNOME-C7 ~]# cat /etc/sysconfig/httpd
# Configuration file for the httpd service.

#
# The default processing model (MPM) is the process-based
# 'prefork' model.  A thread-based model, 'worker', is also
# available, but does not work with some modules (such as PHP).
# The service must be stopped before changing this variable.
#
HTTPD=/usr/local/apache2/bin/httpd.worker        ##表示启动的httpd服务mpm为worker

#
# To pass additional options (for instance, -D definitions) to the
# httpd binary at startup, set OPTIONS here.
#
#OPTIONS=

#
# By default, the httpd process is started in the C locale; to
# change the locale in which the server runs, the HTTPD_LANG
# variable can be set.
#
#HTTPD_LANG=C

#
# By default, the httpd process will create the file
# /var/run/httpd/httpd.pid in which it records its process
# identification number when it starts.  If an alternate location is
# specified in httpd.conf (via the PidFile directive), the new
# location needs to be reported in the PIDFILE.
#
#PIDFILE=/var/run/httpd/httpd.pid

3.1.9. 使用chkconfig管理

[root@GNOME-C7 ~]# chmod 755 /etc/init.d/httpd 
[root@GNOME-C7 ~]# chkconfig --add httpd
[root@GNOME-C7 ~]# chkconfig --level 3 httpd on
[root@GNOME-C7 ~]# chkconfig --list | grep httpd
httpd              0:off    1:off    2:off    3:on    4:off    5:off    6:off

3.1.10. 启动服务

[root@GNOME-C7 ~]# service httpd start
Starting httpd (via systemctl):                            [  OK  ]

3.2.9. 使用chkconfig管理

[root@GNOME-C7 ~]# chmod 755 /etc/init.d/httpd 
[root@GNOME-C7 ~]# chkconfig --add httpd
[root@GNOME-C7 ~]# chkconfig --level 3 httpd on
[root@GNOME-C7 ~]# chkconfig --list | grep httpd
httpd              0:off    1:off    2:off    3:on    4:off    5:off    6:off

3.2.10. 启动服务

[root@GNOME-C7 ~]# service httpd start
Starting httpd (via systemctl):                            [  OK  ]
[root@GNOME-C7 ~]# ss -ant | grep 80
LISTEN     0      128          *:80                       *:*  
[root@GNOME-C7 ~]# ps aux | grep http[d]        ##现在运行httpd的用户是daemon,可以在配置文件中更改
root     114229  0.0  0.0  97508  2536 ?        Ss   18:34   0:00 /usr/local/apache2/bin/httpd
