下面由centos教程栏目给大家介绍centos7怎么使用yum安装lnmp环境，希望对需要的朋友有所帮助！

更新yum源
yum update

yum安装nginx
安装nginx最新源
yum localinstall http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
yum repolist enabled | grep "nginx*"
安装nginx
yum -y install  nginx
启动nginx
| service nginx start |
设置nginx服务器开机自启动
systemctl enable nginx.service

systemctl list-dependencies | grep nginx

使用yum安装mysql5.7
安装mysql源
yum -y localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
yum repolist enabled | grep "mysql.*-community.*"
安装mysql
yum -y install mysql-community-server install mysql-community-devel
启动mysql
service mysqld start
检查mysql启动是否正常
service mysqld status 或者 ps -ef | grep mysql
设置mysqld服务开机自启动
systemctl enable ysqld.service
检查mysqld开机自启动是否设置成功
systemctl list-dependencies | grep mysqld
mysql5.7以后的争强了安全机制, 所以使用yum安装,启动会系统会自动生成一个随机的密码,修改mysql密码；查看mysql的随机密码
grep 'temporary password' /var/log/mysqld.log
使用查询得到的随机密码在终端登录
mysql -u root -p 更改密码(mysql文档规定,密码必须包括大小写字母数字加特殊符号>8位)
ALTER USER 'root'@'localhost' IDENTIFIED BY 'Yourpassword';
退出mysql客户端,用刚才修改的密码登录确保密码修改成功
exit;mysql -u root -p
