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
检查开机自动是否设置成功
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

安装php7.1
安装php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
检查源是否安装成功
yum repolist enabled | grep "webtatic*"
安装php扩展源
yum -y install php71w php71w-fpm
yum -y install php71w-mbstring php71w-common php71w-gd php71w-mcrypt
yum -y install php71w-mysql php71w-xml php71w-cli php71w-devel
yum -y install hp71w-pecl-memcached php71w-pecl-redis php71w-opcache

验证php7.1.x和扩展是否安装成功
php -v

php -m

设置php-fpm并检测php-fpm的运行状态
启动php-fpm：service php-fpm star
