redis下载与安装

redis下载与安装

1. redis下载地址：https://github.com/redis/redis/archive/7.0.5.tar.gz

2. 解压：tar -zxvf redis-7.0.5.tar.gz

3. 编译：

   	make  
   	#需要有gcc支持,否则会编译失败 
   

4. 清除编译：

   	make distclean
   	#make失败后重新make的时候之前用一下
   	make 
   

5. 安装：make PREFIX=/opt/redis7 install

安装redis服务

• 前置，配置环境变量

  1. 打开环境配置： vi /etc/profile
  2. 在环境配置文件中最后追加：

  	export REDIS_HOME=/opt/redis7
  	export PATH=$PATH:$REDIS_HOME/bin	
  

  3. 让配置生效：source /etc/profile

  4. 查看环境变量PATH：echo $PATH

     配置完环境变量redis命令可以在任意目录执行了

• 安装

  1. 进入redis安装根目录utils下：cd utils

  2. 执行install_server.sh 命令: ./install_server.sh

     	这个地方可能会报错
     	
     	vi install_server.sh
     	注释掉下面几行
     
     	#_pid_1_exe="$(readlink -f /proc/1/exe)"
     	
     	#if [ "${_pid_1_exe##*/}" = systemd ]
     	
     	#then
     
     	# echo "This systems seems to use systemd."
     	
     	# echo "Please take...them. Sorry!"
     	
     	# exit 1
     	
     	#fi
     
     	保存退出，即可解决问题
     
     	继续执行 ./install_server.sh
     
     	Please ...port for this instance: [6379] 
     	让我们选择端口号，我们选择默认，回车继续...	    	
     	
     	Copied /tmp/6379.conf => /etc/init.d/redis_6379
     	Installing service...
     	Successfully added to chkconfig!
     	Successfully added to runlevels 345!
     	Starting Redis server...
     	Installation successful!
     	
     	完成后会在/etc/init.d/下生成一个redis_6379可执行文件。
     	
     
     

  3. redis_6379文件内容如下

     #!/bin/sh
     #Configurations injected by install_server below....
     
     EXEC=/opt/redis7/bin/redis-server
     CLIEXEC=/opt/redis7/bin/redis-cli

  4. 执行开启redis只需要执行service redis_6379 start …
