本篇笔记主要讲解如何在centos7.x下配置LNMP环境，其中PHP版本为7.x。如果需要配置6.x的，请参考。
安装一些常用的源
EPEL源
centos6
yum install http://mirrors.ustc.edu.cn/fedora/epel/6/i386/epel-release-6-8.noarch.rpm
centos7
yum install http://mirrors.yun-idc.com/epel/7/x86_64/e/epel-release-7-2.noarch.rpmmysql源
#centos6
yum install http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm
#centos7
yum install http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpmnginx源
#centos6
yum install http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
#centos7
yum install http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm全量更新一遍
yum update参考链接：
安装PHP7
第一步，安装YUM源
sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm第二步，安装PHP7.1和相关依赖库
sudo yum install -y mod_PHP71w PHP71w-cli PHP71w-common PHP71w-gd PHP71w-mbstring PHP71w-mcrypt PHP71w-MysqLnd PHP71w-xml PHP71w-devel第三步，Step 3: configure PHP 7.x
sudo cp /etc/PHP.ini /etc/PHP.ini.bak
sudo vi /etc/PHP.ini安装PHP-fpm
yum install -y PHP7.1-fpm安装redis
yum install -y redis安装git
yum install -y git安装PHP的redis扩展
git clone git://github.com/nicolasff/PHPredis.git
cd PHPredis
PHPize
./configure
make
sudo -s make install
sudo -s
echo "extension=redis.so">/etc/PHP.d/redis.ini
exit
参考：
检测是否有安装：
php -m | grep redis安装nginx
yum install -y nginx安装mysql
sudo yum install -y mysql-server
sudo systemctl start mysqld然后，secure mysql
mysql_secure_installation安装composer
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer安装php-fpm
先安装php的源
yum install -y php71w-fpm安装tmux
yum install -y tmux配置redis
调整daemon状态配置php-fpm
调整运行用户，deploy
权限问题，会导致nginx层报错，说script file 找不到的问题配置nginx
- 调整运行用户，如deploy
- 调整对应文件夹的权限
- 全局的日志文件夹权限
- 默认的缓存文件夹配置系统的文字系统
vi /etc/environment
LC_ALL=en_US.utf-8
LANG=en_US.utf-8
配置基础用户
useradd -m deploy
useradd www
usermod -a -G deploy www
usermod -aG wheel deploy
