PHP7

1.安装epel-release

通过命令:

yum -y install epel-release

成功安装。

2.安装PHP7

终端再次运行如下命令:

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

成功获取PHP7的yum源,然后再执行:

php安装以及安装扩展

yum install php70w  php70w-devel php70w-fpm php70w-gd php70w-mysqli php70w-mbstring

nginx

centos7系统库中默认是没有nginx的rpm包的,所以我们自己需要先更新下rpm依赖库

1.使用yum安装nginx需要包括Nginx的库,安装Nginx的库

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

2.使用下面命令安装nginx

yum install nginx

3.启动Nginx

service nginx start

systemctl start nginx.service

mysql

1.下载mysql的repo源

wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

2.安装mysql-community-release-el7-5.noarch.rpm包

sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm

安装这个包后,会获得两个mysql的yum repo源:/etc/yum.repos.d/mysql-community.repo,/etc/yum.repos.d/mysql-community-source.repo。

3.安装mysql

sudo yum install mysql-server

根据提示安装就可以了,不过安装完成后没有密码,需要重置密码

4.重置mysql密码

mysql -u root

登录时有可能报这样的错:ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2),原因是/var/lib/mysql的访问权限问题。下面的命令把/var/lib/mysql的拥有者改为当前用户:

sudo chown -R root:root /var/lib/mysql

重启mysql服务

service mysqld restart

接下来登录重置密码:

mysql -u root  //直接回车进入mysql控制台
mysql > use mysql;
mysql > update user set password=password('123456') where user='root';
mysql > exit;
