各位老铁们好，相信很多人对centos 6.5 yum 升级php都不是特别的了解，因此呢，今天就来为大家分享下关于centos 6.5 yum 升级php以及centos7升级到centos8的问题知识，还望可以帮助大家，解决大家的一些困惑，下面一起来看看吧！
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

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

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:

CentOSyumphpmcrypt扩展安装方法
使用 yum install php-mcrypt安装mcrypt扩展时会提示没有安装包
Setting up Install Process
No package php-mcrypt available.
Error: Nothing to do
mcrypt是加密扩展库，加载了它可以用他里面自带的22种加密解密算法
CentOS6默认安装的是php5.3.2
默认的 redhat repos php中是没有 mcrypt扩展的
根据红帽的官方消息（）RHEL不打算添加PHP的mcrypt的支持
Joe Orton 2010-08-05 04:47:17 EDT
Thanks for the report.
We are not planning to ship mcrypt support for PHP.
解决方法：
从php官网下载新的php 5.3源码包后，解压到本地目录
进入解压目录下的 ext目录后会发现有 mcrypt，
进入 mcrypt目录
#cd/ext/mcrypt
#phpize
注意：如果报-bash:phpize not Found那么 yum install php-devel就可以使phpize进行动态编译安装扩展
#./configure-with-php-config=/usr/sbin/php/bin/php-config
#make&& make install
出现：
----------------------------------------------------------------------
Libraries have been installed in:
/var/php-5.3.10/ext/mcrypt/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath-Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Build complete.
Don't forget to run'make test'.

已安装成功！
再次查看 phpinfo，可以看到mcrypt扩展详情。
centos通过yum安装php的教程
先给大家介绍下centos通过yum安装php
1、添加php的yum软件仓库
sudo rpm-Uvh
2、安装php相关软件，执行过程中全部选择yes即可
sudo yum install php71w.x86_64 php71w-cli.x86_64 php71w-common.x86_64 php71w-gd.x86_64 php71w-ldap.x86_64 php71w-mbstring.x86_64 php71w-mcrypt.x86_64 php71w-mysql.x86_64 php71w-pdo.x86_643、安装php71-fpm
sudo yum install php71w-fpm.x86_64
等待安装完成输入php-version查看php版本
ps:下面看下CentOS 7下Yum安装PHP7.2步骤
1、安装源
安装php72w，是需要配置额外的yum源地址的，否则会报错不能找到相关软件包。
php高版本的yum源地址，有两部分，其中一部分是epel-release，另外一部分来自webtatic。如果跳过epel-release的话，安装webtatic的时候，会有错误爆出。
所以，这里需要的命令是：
rpm-Uvh
rpm-Uvh
当然，您也可以选择下面的这个命令，也是一样的效果。
yum install epel-release-y
rpm-Uvh
2、清除历史版本
为了防止CentOS上面发生php冲突，所以，这个命令还是先执行一下更好些。
yum-y remove php*
3、安装扩展包
事实上，这里面的对应扩展库很多，这里大家一定要注意cli和fpm这两个包，而其它的相关包就看您需要了。
yum-y install php72w php72w-cli php72w-fpm php72w-common php72w-devel还有比较豪华的版本：
yum-y install php72w php72w-cli php72w-fpm php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml4、安装完成以后，启动服务
systemctl enable php-fpm.service
systemctl start php-fpm.service5、安装成功
总结
以上所述是小编给大家介绍的centos通过yum安装php的教程，希望对大家有所帮助！
