Centos7 php升级与依赖包下载

 检查当前安装的PHP包

• [root@kk ~]#  yum list installed | grep php

移除当前PHP安装包，要是移除就要重新下载，不移除就升级，版本相差太大建议移除重新下载（我反正没有移除）

• [root@kk ~]# yum remove php*

查看当前yum源都提供了哪些可安装的PHP版本

• [root@kk ~]# yum list php*

注意：默认的yum源无法升级PHP，需要添加第三方yum源，我们选择webtatic库

CentOs 5.x

• rpm -Uvh http://mirror.webtatic.com/yum/el5/latest.rpm

CentOs 6.x

• rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm

CentOs 7.X

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

看一下当前yum源能下载哪些php的包

• [root@kk yum.repos.d]# yum list php*

• 会发现只php55w-php72w,没有我想要的php73w,所以要用别的源来下载

我们先择REMI 源

• [root@kk yum.repos.d]# yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm 

使用remi 源 升级 PHP 7.3

• 更改[remi]区域的代码块为如下，相同则不用更改

• [root@kk yum.repos.d]# vim remi.repo 
  [remi]
  name=Remi's RPM repository for Enterprise Linux 7 - $basearch
  #baseurl=http://rpms.remirepo.net/enterprise/7/remi/$basearch/
  #mirrorlist=https://rpms.remirepo.net/enterprise/7/remi/httpsmirror
  mirrorlist=http://cdn.remirepo.net/enterprise/7/remi/mirror
  enabled=0
  gpgcheck=1
  gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
  
  [root@kk yum.repos.d]# vim remi-php73.repo 
  [remi-php73]
  name=Remi's PHP 7.3 RPM repository for Enterprise Linux 7 - $basearch
  #baseurl=http://rpms.remirepo.net/enterprise/7/php73/$basearch/
  mirrorlist=https://rpms.remirepo.net/enterprise/7/php73/httpsmirror
  mirrorlist=http://cdn.remirepo.net/enterprise/7/php73/mirror
  enabled=1
  gpgcheck=1
  gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

然后进行升级

• [root@kk yum.repos.d]# yum -y upgrade php*

• 查看版本

[root@kk yum.repos.d]# php -v

不要忘记了启动php-fpm

• [root@kk yum.repos.d]# systemctl start php-fpm
  [root@kk yum.repos.d]# systemctl enable php-fpm
  [root@kk yum.repos.d]# netstat -lntup|grep php
  tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      4536/php-fpm: maste

升级成功（升其它版本方法一致）

这里再说一下安装php73w依赖包

yum install -y 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

这里安装后启动php-fpm有些不一样，名称叫php73-php-fpm，才能启动

如果想要把这些包只下载不安装

yum install -y --downloadonly --downloaddir=/tmp/kk  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

wordpress无法将上传的文件移动至wp-content/uploads/2020/01。

这说一下要是完全升级，原先的php默认配置文件会发生变化，要去/etc/opt/remi/php73/php-fpm.d/www.conf，下把用户和用户组改成我们设定好的www，然后再重启php-fpm就完成了
