虚拟机上的一台centos7，本来只打算升级一下php5到php7的，想来一直没试过update，索性练习学习一下。

首先最重要的当然是备份了，因为是虚拟机，备份非常方便，整个快照一下即可。

查看一下现在的版本

# mysql -V
mysql  Ver 15.1 Distrib 5.5.64-MariaDB, for Linux (x86_64) using readline 5.1
# php -v
PHP 5.4.16 (cli) (built: Aug 11 2016 21:24:59)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies
# httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:   Jul 18 2016 15:30:14
# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)

然后运行升级

# yum clean all
# yum update

中途输入y回车确认一下升级

# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)

速度还是挺快的，几分钟就完事了，再查一下版本已经到7.7.1908了，为了彻底生效，还是重启一下吧。

继续升级PHP、MySQL(MariaDB)、Apache

数据库升级可能是最方便最顺利的，因为官方提供了yum源，按照步骤安装就行了。MariaDB官方链接点击这里

# cd /etc/yum.repos.d
# vim MariaDB.repo
# MariaDB 10.4 CentOS repository list - created 2020-04-29 05:43 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.4/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
# yum clean all

Bye
# mysql -V
mysql  Ver 15.1 Distrib 10.4.12-MariaDB, for Linux (x86_64) using readline 5.1

Apache好久没用过了，官方版本好像是2.4.43(released 2020-04-01)，但我几年前装的怎么就是2.4.6？本地Windows几年前装的WampServer中的版本就是2.4.37，不知道为什么，既然这样，就只能系统默认的2.4.6算了吧。

http://httpd.apache.org/download.cgi

# yum install httpd
Is this ok [y/d/N]: y
# systemctl start httpd
# systemctl enable httpd

继续升级PHP，主要是yum源不好找啊，为什么MariaDB官方能提供，其它的就不行呢？主要是centos更新了。

# rpm -qa |grep php
# yum remove -y php*
# yum info php //查询到可安装的php版本是5.4.16
# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
# yum clean all
# yum makecache
# yum info php //还是没变，换一个repo源

试了阿里、清华、网易、epel多个源，可能只是官方的镜像吧，都是5.4.16。就算这样，更新centos系统了，也该升级一下相应软件的版本吧？不过centos8中好像默认是7.2以上了。

最后找到remi这个源，还挺丰富的，各个版本都有，安装也顺利，国外的，就是不熟悉，不知道来源安全与否。

# yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
Is this ok [y/d/N]: y
# cd /etc/yum.repos.d
# vim remi-php74.repo //安装哪个版本就修改哪个

将此区块enabled=0修改为enabled=1，保存退出。

[remi-php74]
name=Remi's PHP 7.4 RPM repository for Enterprise Linux 7 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/7/php74/$basearch/
#mirrorlist=https://rpms.remirepo.net/enterprise/7/php74/httpsmirror
mirrorlist=http://cdn.remirepo.net/enterprise/7/php74/mirror
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
# yum clean all
# yum makecache
# yum info php //此时可以看到php7.4.5的版本了。
# yum install php php-fpm
Is this ok [y/d/N]: y
# systemctl start php-fpm
# systemctl enable php-fpm
# systemctl restart httpd

成功！
