	记录几个常用的CentOS 7下的yum源,包括PHP7,MariaDB,Redis,Nginx等,以及阿里云源,方便虚拟机或云主机上安装这些软件。 
	  
	1.PHP7 remi源
	使用remi源: 
	
	
		  
		
			
				
					| 
							1 
							2 | 
							
								$ sudo rpm --import http://rpms.famillecollet.com/RPM-GPG-KEY-remi 
								$ sudo rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm |  
	  
	2.MariaDB 10.1
	Here is your custom MariaDB YUM repository entry for CentOS. Copy and paste it into a file under /etc/yum.repos.d/ (we suggest naming the file MariaDB.repo or something similar). 
	
	
		  
		
			
				
					|  | 
							
								# MariaDB 10.1 CentOS repository list - created 2016-03-31 09:25 UTC 
								# http://mariadb.org/mariadb/repositories/ 
								[mariadb] 
								name = MariaDB 
								baseurl = http://yum.mariadb.org/10.1/centos7-amd64 
								gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB 
								gpgcheck=1 |  
	执行安装命令: 
	
		  
		
			
				
					|  | 
							
								sudo yum install MariaDB-server MariaDB-client |  
	  
	3.Redis
	
		
			
				
					|  | 
							
								wget http://download.redis.io/redis-stable.tar.gz 
								tar xvzf redis-stable.tar.gz 
								cd redis-stable 
								make |  
	设置service方式启动,参见:quickstart和Redis生成环境自动启动 
	4.Nginx 1.8
	To add NGINX yum repository, create a file named /etc/yum.repos.d/nginx.repo and paste one of the configurations below: 
	CentOS: 
	
	
		
			
				
					|  | 
							
								[nginx] 
								name=nginx repo 
								baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ 
								gpgcheck=0 
								enabled=1 |  
	  
	5.阿里云
	① 备份
	
		  
		
			
				
					|  | 
							
								mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup |  
	  
	② 下载新的CentOS-Base.repo 到/etc/yum.repos.d/
	CentOS 7 
	
	
		
			
				
					|  | 
							
								wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo |
