CentOS 7 装2个版本PHP共存,网站迁移服务器

在一台高性能服务器上实现两个项目共存于不同版本的PHP环境，具体操作如下：

需求是将原本在两台服务器上分别运行的项目，一个在PHP5.6下，另一个在PHP7.4下，合并至一台高性能服务器。

首先，通过手动启用宝塔的 apache，确保Apache服务运行正常。

接着，确保Apache能够支持多版本的PHP环境，让php-V显示版本为php 7.4。

然后，配置Apache以使得ip地址能直接访问web内容，实现网站的正常访问。

利用Apache虚拟目录Alias功能，将深层的目录结构映射为一级目录，优化SEO。

进一步，实现SSL支持，为网站提供安全的连接。

为了方便管理和切换网站PHP版本，可通过命令来控制单个网站的启动与停止。

结合BT命令行大全，可以实现更多高级操作和自动化管理。

centOS怎样强制卸载PHP以及自定义安装PHP

查看php版本命令：

#php-v

这个命令是删除不干净的

#yum remove php

因为使用这个命令以后再用

#php-v

还是会看到有版本信息的。。。。。

必须强制删除

#rpm-qa|grep php

提示如下

#php-pdo-5.1.6-27.el5_5.3

#php-mysql-5.1.6-27.el5_5.3

#php-xml-5.1.6-27.el5_5.3

#php-cli-5.1.6-27.el5_5.3

#php-common-5.1.6-27.el5_5.3

#php-gd-5.1.6-27.el5_5.3

注意卸载要先卸载没有依赖的

pdo是mysql的依赖项；common是gd的依赖项；

例如：# rpm-e php-pdo-5.1.6-27.el5_5.3

error: Failed dependencies:

php-pdo is needed by(installed) php-mysql-5.1.6-27.el5_5.3.i386

所以正确的卸载顺序是：

# rpm-e php-mysql-5.1.6-27.el5_5.3

# rpm-e php-pdo-5.1.6-27.el5_5.3

# rpm-e php-xml-5.1.6-27.el5_5.3

# rpm-e php-cli-5.1.6-27.el5_5.3

# rpm-e php-gd-5.1.6-27.el5_5.3

# rpm-e php-common-5.1.6-27.el5_5.3

再用# php-v

查看版本信息已经没有提示

安装最新的PHP

wget

tar xzvf php-5.3.6.tar.gz

cd php-5.3.6

./configure--prefix=/usr/local/php

阿里云上的centos 7.2怎么yum安装php 5.6

因之前通过网易的 centos镜像，将阿里云的 centos升级到最新版了，乘自己的项目尚未开始正式开发，遂将所有的相应环境都升级到最高。

查看 centos版本：

[root@iZ23d~]# cat/etc/centos-release

CentOS Linux release 7.2.1511(Core)

1、删除之前的 php版本：

[root@iZ23d~]# yum remove php* php-common

Loaded plugins: langpacks

Repository base is listed more than once in the configuration

Repository updates is listed more than once in the configuration

Repository extras is listed more than once in the configuration

Repository centosplus is listed more than once in the configuration

No Match for argument: php-5.4.16

No Match for argument: php-5.4.16.tar.gz

No Match for argument: php-7.0.1RC1

No Match for argument: php-7.0.1RC1.tar.gz

No Match for argument: phpMyAdmin-4.4.0.tar.gz

No Match for argument: php-common

No Packages marked for removal

2、rpm安装 Php7相应的 yum源：

[root@iZ23d~]# rpm-Uvh

Retrieving

Preparing...################################# [100%]

package webtatic-release-7-3.noarch is already installed

3、直接yum安装php7：

[root@iZ23d~]# yum install php70w

Loaded plugins: langpacks

Repository base is listed more than once in the configuration

Repository updates is listed more than once in the configuration

Repository extras is listed more than once in the configuration

Repository centosplus is listed more than once in the configuration

Complete!

4、检查 php版本：

[root@iZ23d~]# php-v

PHP 7.0.0(cli)(built: Dec 2 2015 20:42:32)( NTS)

[root@iZ23d2e6hoqZ~]#

以上显示安装成功！

5、重启 Apache，查看 phpinfo:

[root@iZ23d~]# systemctl restart httpd.service

检查phpinfo:

PHP Version 7.0.0
