1. Install Redis step

1.1. 参考：

• http://jasdeep.ca/2012/05/installing-redis-on-mac-os-x/
• http://www.jianshu.com/p/6b5eca8d908b

1.2. 源码安装

1. 下载：从Redis官网下载最新版本的redis安装文件，本次安装使用的最新稳定版本是4.0.2；

    wget http://download.redis.io/releases/redis-4.0.2.tar.gz
   

2. 解压到指定目录；

    tar xzf redis-4.0.2.tar.gz
   

3. 使用make test命令进行编译测试，确定没有问题；

4. 使用make命令进行编译；

    ➜  source sudo wget http://download.redis.io/releases/redis-3.2.9.tar.gz
    ➜  source sudo tar -xzvf redis-3.2.9.tar.gz 
    ➜  source pwd
    /usr/local/source
    ➜  source cd ..
    ➜  local sudo ln -s /usr/local/source/redis-3.2.9 redis
    ➜  local cd redis 
    ➜  redis sudo make test
   

5. 使用make install命令进行编译安装；

    ➜  redis sudo make install
    cd src && /Library/Developer/CommandLineTools/usr/bin/make install
        INSTALL redis-sentinel
        CC redis-cli.o
        LINK redis-cli
        CC redis-benchmark.o
        LINK redis-benchmark
        INSTALL redis-check-rdb
   
    Hint: It's a good idea to run 'make test' ;)
   
        INSTALL install
        INSTALL install
        INSTALL install
        INSTALL install
        INSTALL install
   

6. 在终端输入redis-server来测试是否安装成功；

    ➜  redis redis-server
    45397:C 19 May 13:26:08.639 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
    45397:M 19 May 13:26:08.641 * Increased maximum number of open files to 10032 (it was originally set to 2560).

          _.-``    `.  `_.  ''-._           Redis 3.2.9 (00000000/0) 64 bit

      `-._    `-._  `-./  _.-'    _.-'                                   
     |`-._`-._    `-.__.-'    _.-'_.-'|                                  
     |    `-._`-._        _.-'_.-'    |           http://redis.io        
      `-._    `-._`-.__.-'_.-'    _.-'                                   
     |`-._`-._    `-.__.-'    _.-'_.-'|                                  
     |    `-._`-._        _.-'_.-'    |                                  
      `-._    `-._`-.__.-'_.-'    _.-'                                   
          `-._    `-.__.-'    _.-'                                       
              `-._        _.-'                                           
                  `-.__.-'                                               
   
    45397:M 19 May 13:26:08.646 # Server started, Redis version 3.2.9
    45397:M 19 May 13:26:08.646 * The server is now ready to accept connections on port 6379
   

7. 在redis目录下创建三个目录:bin,etc,db
8. 把/usr/local/redis/src目录下的mkreleasehdr.sh，redis-benchmark， redis-check-dump， redis-cli， redis-server复制到bin目录：

    ➜  redis sudo cp src/redis-server src/redis-cli src/mkreleasehdr.sh src/redis-benchmark bin
   

9. 把/usr/local/redis/redis.conf文件复制到etc目录下：

    ➜  redis sudo cp redis.conf etc
   

10. 修改etc下的配置文件：redis.conf

    # 守护模式
    daemonize yes
    #设置进程锁文件
    pidfile /usr/local/redis/redis.pid
    #日志文件位置
    logfile /usr/local/redis/log-redis.log
    

11. 保存后，启动redis

    ➜  redis sudo ./bin/redis-server etc/redis.conf 
    Password:
    ➜  redis ps -ef | grep 'redis'
        0 45662     1   0  1:51下午 ??         0:00.01 ./bin/redis-server 127.0.0.1:6379 
      501 45669 45402   0  1:51下午 ttys003    0:00.01 grep --color=auto --exclude-dir=.bzr --exclude-dir=CVS --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn redis
    

12. 查看日志文件

    ➜  redis tail -f log-redis.log 
      `-._    `-._`-.__.-'_.-'    _.-'                                   
     |`-._`-._    `-.__.-'    _.-'_.-'|                                  
     |    `-._`-._        _.-'_.-'    |                                  
      `-._    `-._`-.__.-'_.-'    _.-'                                   
          `-._    `-.__.-'    _.-'                                       
              `-._        _.-'                                           
                  `-.__.-'                                               
    
    45662:M 19 May 13:51:10.277 # Server started, Redis version 3.2.9
    45662:M 19 May 13:51:10.277 * The server is now ready to accept connections on port 6379
    

13. 使用客户端连接测试

    ➜  redis ./bin/redis-cli 
    127.0.0.1:6379> ping
    PONG
    127.0.0.1:6379> ping test
    "test"
    

1.3. 安装过程可能遇到的问题

• make[3]: gcc: Command not found 在make test的时候，遇到错误：make[3]: gcc: Command not found，由于用的虚拟机，没有安装gcc编译器，所以报错，解决办法是使用yum进行安装：

    # yum install gcc
  

• zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory

  make test时报错：

    zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory
    zmalloc.h:55:2: error: #error "Newer version of jemalloc required"
    make[1]: *** [adlist.o] Error 1
    make[1]: Leaving directory `/usr/local/source/redis-4.0.2/src'
    make: *** [test] Error 2
  

  原因分析：

    Allocator  
    ---------  
  
    Selecting a non-default memory allocator when building Redis is done by setting  
    the `MALLOC` environment variable. Redis is compiled and linked against libc  
    malloc by default, with the exception of jemalloc being the default on Linux  
    systems. This default was picked because jemalloc has proven to have fewer  
    fragmentation problems than libc malloc.  
  
    To force compiling against libc malloc, use:  
  
        % make MALLOC=libc  
  
    To compile against jemalloc on Mac OS X systems, use:  
  
        % make MALLOC=jemalloc
  

  说关于分配器allocator， 如果有MALLOC 这个 环境变量， 会有用这个环境变量的 去建立Redis。

  而且libc 并不是默认的 分配器， 默认的是 jemalloc, 因为 jemalloc 被证明 有更少的 fragmentation problems 比libc。

  但是如果你又没有jemalloc 而只有 libc 当然 make 出错。 所以加这么一个参数。

  解决办法

    make MALLOC=libc
  

• couldn't execute "tclsh8.5": no such file or directory

  异常原因：没有安装tcl

  解决方案：yum install -y tcl。
