Linux之Redhat PHP7.4.6自行编译安装

背景

安装的 Redhat 下默认php版本是5.3，想要更新到7.4.6版本实现多版本开发使用，但是服务器是处于断网状态。

步骤

1. 从官网下载对应版本的安装包 php-7.4.6.tar.gz (sig)，然后通过 Xftp6 上传到服务器

2. 解压，进入到解压目录，执行一下配置命令 ./configure 配置一下php，此处我用 --prefix 指定了一个安装目录

   [root@lbsdb php-7.4.6]# ./configure --prefix=/usr/local/php7.4.6
   

3. 接下来继续安装php

   	[root@lbsdb php-7.4.6]# ./configure --prefix=/usr/local/php7.4.6

   	Thank you for using PHP.
   
   	```
   
   

FQA.

• 安装过程中出现错误信息，提示你缺少 libxml-2.0 ，而且得是版本不低于 2.7.6

  Configuring extensions
  checking io.h usability... no
  checking io.h presence... no
  checking for io.h... no
  checking for strtoll... yes
  checking for atoll... yes
  checking whether to build with LIBXML support... yes
  checking for libxml-2.0 >= 2.7.6... no
  configure: error: Package requirements (libxml-2.0 >= 2.7.6) were not met:
  
  No package 'libxml-2.0' found
  
  Consider adjusting the PKG_CONFIG_PATH environment variable if you
  installed software in a non-standard prefix.
  

• 解决办法：安装 包libxml-2.0，去访问 Linux/Unix软件包网站，
  此处注意你的 libxml2-devel的版本 ，我的环境版本是2.7.6

  [root@lbsdb download]# yum list|grep libxml2-devel
  libxml2-devel.i686                        2.7.6-21.el6_8.1               base   
  libxml2-devel.x86_64                      2.7.6-21.el6_8.1               base 
  

  所以找了对应的2.7.6版本的进行下载，进入到下载页面，找到下方Download栏目，复制链接进行下载。

  下载完成后，上传到服务器，用 rpm 命令安装

  [root@lbsdb download]# rpm -ivh libxml2-devel-2.7.6-21.el6_8.1.x86_64.rpm 
  Preparing...                ########################################### [100%]
