[PHP知识库]centos7自定义RPM软件包（php-7.4）

一、基本概念

1. 官方未提供RPM包

2. 官方的RPM无法自定义

3. 大量源码包，希望提供统一的软件管理机制

二、软件打包流程

1.准备源码包软件

? 案例：以下载php7.4版本为案例：官方软件包下载地址：PHP: Downloads

2. 安装rpm-build

[root@module ~]# yum -y install rpm-build   #安装软件
[root@module ~]# -ba xxx.spec               #会提示失败，自动创建目录
[root@module ~]# ls /root/                  #查看rpmbuild是否自动创建成功

3. 准备源码包软件

[root@module ~]# cp php-7.4.27.tar.gz /root/rpmbuild/SOURCES/  #将提前下载好的源码包拷贝到SOURCES目录

4. 编写编译配置文件

[root@module x86_64]# vim /root/rpmbuild/SPECS/php.spec #编写编译配置文件
%global __python /usr/local/bin/python3    #指定使用python3，根据python安装路径填写；默认是用的python2，编译过程中会有问题
%define _user www
%define _group www
%define _prefix /usr/local/php

5. 过程中遇到的问题

问题1：error: Installed (but unpackaged) file(s) found:

error: Installed (but unpackaged) file(s) found:
   /etc/php-fpm.conf.default
   /etc/php-fpm.d/www.conf.default


RPM build errors:
    Installed (but unpackaged) file(s) found:
   /etc/php-fpm.conf.default
   /etc/php-fpm.d/www.conf.default
#解决方案：
#RPM包的spec脚本中没有包含但又被安装的文件，把这个文件添加在%files段就可以了，如下
%file
/etc/php-fpm.conf.default
/etc/php-fpm.d/www.conf.default

问题2：No package oniguruma found?

# 编译安装 PHP 7.4 提示 No package oniguruma found
# 使用 --with-mbstring 参数，则需要安装 oniguruma
#oniguruma 是一个处理正则表达式库，php7.4 中，mbstring 正则表达式处理功能对这个包有依赖。所以，安 
 装php7.4前需要安装oniguruma和oniguruma-devel 两个软件包

#下载地址：https://pkgs.org/download/oniguruma 和 https://pkgs.org/download/oniguruma-devel 

#方法1：一般安装epel 然后安装即可：
[root@module ~]# yum install -y epel-release
[root@module ~]# yum install -y oniguruma oniguruma-devel

#方法2：行手动安装/更新epel:
[root@module ~]# rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
[root@module ~]# yum install -y https://www.elrepo.org/elrepo-release-7.el7.elrepo.noarch.rpm
[root@module ~]# yum install -y oniguruma oniguruma-devel

#方法3：Centos7，直接执行以下命令即可安装：
[root@module ~]# yum -y install https://rpms.remirepo.net/enterprise/7/remi/x86_64/oniguruma5php-6.9.6-1.el7.remi.x86_64.rpm
[root@module ~]# yum -y install https://rpms.remirepo.net/enterprise/7/remi/x86_64/oniguruma5php-devel-6.9.6-1.el7.remi.x86_64.rpm

#方法4：如果报冲突
[root@module ~]# yum remove epel-release #如果报冲突，先把冲突的包删除
[root@module ~]# rpm -ivh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@module ~]# yum install -y oniguruma oniguruma-devel
[root@module ~]# yum clean all && yum makecache
[root@module ~]# yum repolist all #检查 epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 是否启用

问题3：Bad exit status from /var/tmp/rpm-tmp.CwPoYe (%install)

error: Bad exit status from /var/tmp/rpm-tmp.CwPoYe (%install)

RPM build errors:
Bad exit status from /var/tmp/rpm-tmp.CwPoYe (%install)

#处理方式在：spec文件最上方添加
%global __python /usr/bin/python3

原因：生成python二进制文件的时候使用了python2

问题4：

编译安装libiconv库
[root@module ~]# wget https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.16.tar.gz #下载软件包
[root@module ~]# cd libiconv-1.16 #进入目录
[root@module ~]# mkdir /root/liconv
[root@module ~]# ./configure --prefix=/root/liconv
[root@module ~]# make && make install #源码方式安装
[root@module ~]# cp -f /root/liconv/libcharset.so.1 /usr/lib  #拷贝库文件
[root@module ~]# cp -f /root/liconv/libiconv.so.2 /usr/lib
[root@module ~]# ln -s /usr/lib/libiconv.so.2 /usr/lib/libiconv.so #该库链接到/usr/lib/libiconv.so

若还是提示cannot find -liconv
[root@module ~]# vim /root/rm.sh  #编写脚本文件，目的删除-static
#!/bin/sh
echo "begin"
gcc -static -o mtserver mtsocket.c current.c  ini.c dcmscomm.c public.c sqlite3.c cjson.c config.c db.c dbcd.c dcms01dev.c power.c common.c mtserver.c  -lm -liconv -lrt -ldl -lpthread
