centos通过yum安装php7,mysql5.7,nginx

PHP

首先在yum里加入repo源。

centos6:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

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

centos7:

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

导入完毕后运行

yum install php70w

相关扩展可选:php70w-gd php70w-mbstring等等

mysql5.7

下载mysql源包

wget http://repo.mysql.com//mysql57-community-release-el7-7.noarch.rpm

如果没有wget首先安装wget:

yum install wget

之后添加repo到yum:

rpm -Uvh mysql57-community-release-el7-7.noarch.rpm

安装mysql服务

yum install mysql-community-server

msyql客户端:

yum install mysql-community-client

mysql5.7之后的版本为了安全起见会随机生成一个初始密码放在/var/log/mysqld.log

找到日志中的

A temporary password is generated for root@localhost:

之类就是初始密码。

修改mysql密码

拿到初始密码之后，登录mysql修改密码

mysql -u root -p

1: 修改密码，必须有大小写，含数字特殊符号，长度8位及以上

SET PASSWORD = ‘your password’;

2: 设置密码不过期；

ALTER USER root@localhost PASSWORD EXPIRE NEVER;

3: 刷新权限表;

flush privileges;

nginx

添加repo源

rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

安装

yum install nginx
