PHP
1缅糟、由于linux的yum源不存在php7.x枯夜，所以我們要更改yum源：
# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
2弯汰、yum查詢安裝php71w
# yum search php71w
3、yum 安裝php71w和各種拓展湖雹，選自己需要的即可咏闪。
//最好組件間一個(gè)空格，可能我因?yàn)樵诰庉嬑恼碌臅r(shí)候多按了空格摔吏，再次安裝的時(shí)候從這里拷貝過去的命令鸽嫂，結(jié)果沒能安裝mysqlnd組建，導(dǎo)致訪問服務(wù)器時(shí)征讲，php無法連接數(shù)據(jù)庫据某。
#yum install php71w php71w-cli php71w-common php71w-devel php71w-embedded php71w-fpm php71w-gd php71w-mbstring php71w-mysqlnd php71w-opcache php71w-pdo php71w-xml
Ps:systemclt restart httpd apache 即可支持php
Mysql
1、下載并安裝MySQL官方的 Yum Repository
# wget -i -c http://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm
# yum -y install mysql80-community-release-el7-3.noarch.rpm
- 安裝mysql-server
//
# yum -y install mysql-community-server
- MySQL數(shù)據(jù)庫設(shè)置
- 啟動
# service mysqld start
此時(shí)MySQL已經(jīng)開始正常運(yùn)行诗箍，不過要想進(jìn)入MySQL還得先找出此時(shí)root用戶的密碼癣籽，通過如下命令可以在日志文件中找出密碼：
# grep "password" /var/log/mysqld.log
- 修改密碼
//密碼規(guī)則：大寫+小寫+數(shù)字+特殊字符 ，缺一不可
alter user root@'localhost' identified by 'Xaaaaaa123456.'
