Centos如何通过yum安装php7？

随着PHP的升级迭代，老的php版本陵扰在一些高并发，情况下越来越吃力，PHP7+顺势而生，随着swoole的扩展协程在php中也变得得以实现，下面看下怎么在centos下升级对应的php吧。

首先确定centos版本

1.通过cat/etc/redhat-release本机用到的是Centos6.2版本

2.由于是升级php，为了防止冲突我们使用rpm_qa|grepphp看看洞汪蠢系统中是否有PHP，然后我们remove掉他yumremove_yphp*，以免影响冲突。

3.接下来我们来安装php7.2，我的安装过程可谓一波三折啊，跟着我看看踩了的那些坑吧。

因为默认的yum源没有php7.2，因此我们必须额外安装yum源

配置安装yum源EPELandRemirepository

Centos7系列:

Centos6系列:

然而悲催的是第一步都出错了，竟然提示打不开纳陪rpm，此处不要慌张，只需要yumupdate_ynss即可nss(Linux名称解析服务)

2)接下来安装yum-utils

yuminstall-yyum-utils

执行完后我们通过以下命令

yum-config-manager--enableremi-php72

启用php72这里注意只是启用了，但是具体的还得通过以下命令来安装

yuminstall-yphpphp-mcryptphp-cliphp-gdphp-curlphp-mysqlphp-ldapphp-zipphp-fileinfophp-fpmphp-develphp-mbstring

What？又报错这又是什么原因呢看着提示是yum找不到。不要怕此时应该是python版本问题导致的。我们只需要将python重新软链下即可

rm-rf/usr/bin/python&&ln-s/usr/bin/python2.6/usr/bin/python

至此php7.2安装完成。

先安装前面的教程，再安装后面的

安装PHP

1、安装PHP73

1.1、卸载旧版本PHP

yum remove php*

1.2、安装EPEL：

sudo yum install epel-release

1.3、安装remi（选一个）:

sudo rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

1.4、查看目前手镇慧毕答有php的什么版本（可忽略）

sudo yum list php*

1.5、列出所有的php相关的rpm包（可忽略）

rpm -qa|grep php

1.6、删除php相关的rpm包（一次旅兄只能删除一个）（可忽略）

rpm -e php72w-mysqlnd-7.2.17-1.w7.x86_64

1.7、列出remi仓库下所有PHP7.3可用模块。（可忽略）

yum --enablerepo=remi-php73 search php | grep php73

1.8、安装PHP 7.3

yum --enablerepo=remi-php73 install php

1、安装 PHP7.3：

（解决yum安装apache关联不了PHP的问题，用以下命令安装）

yum --enablerepo=remi-php73 install php

安装模块

yum --enablerepo=remi-php73 install php73-php-fpm php73-php-cli php73-php-bcmath php73-php-gd php73-php-json php73-php-mbstring php73-php-mcrypt php73-php-mysqlnd php73-php-opcache php73-php-pdo php73-php-pecl-crypto php73-php-pecl-mcrypt php73-php-pecl-geoip php73-php-recode php73-php-snmp php73-php-soap php73-php-xml

2、设置开机启动、运行服务：

systemctl enable php73-php-fpm

systemctl start php73-php-fpm

3、查找php.ini位置：

find /etc/opt/remi/php73 -name php.ini

/etc/opt/remi/php73/php.ini

找到apache的配置文件：httpd.conf

sudo find / -name httpd.conf

位置如下：

/etc/httpd/conf/httpd.conf

5、PHP日常 *** 作

systemctl restart php73-php-fpm #重启

systemctl start php73-php-fpm #启动

systemctl stop php73-php-fpm #关闭

systemctl status php73-php-fpm #检查状态

php -m #查看PHP已安装拓展模块

php -v #查看PHP版本

因之前通过网易的 centos 镜像，将阿里乎裤谨云的 centos 升岁基级到最新版了，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、删除之前的纯颂 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-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 https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

Retrieving https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

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

4、检查 php 版本：

[root@iZ23d ~]# php -v

[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:
