1. 下载并安装 redis 2.6.16版
sudo mkdir /usr/local/src/Redis
cd /usr/local/src/Redis
sudo wget http://download.redis.io/releases/redis-2.6.16.tar.gz
tar -zxf redis-2.6.16.tar.gz
cd redis-2.6.16
sudo make
2. 检验编译是否 正确
sudo make test
- <span style="font-size:14px;">sounion@ubuntu:/usr/local/src/redis-2.6.16$ make test
- cd src && make test
- make[1]: Entering directory `/usr/local/src/redis-2.6.16/src‘
- You need tcl 8.5 or newer in order to run the Redis test
- make[1]: *** [test] Error 1
- make[1]: Leaving directory `/usr/local/src/redis-2.6.16/src‘
- make: *** [test] Error 2
- </span>
安装 tcl 8.5 后可以解决上述编译错误。
- <span style="font-size:14px;">sounion@ubuntu:/usr/local/src/redis-2.6.16$ sudo apt-get install tcl

3. 手工启动redis，测试redis是否运行正常
a)执行命令手工启动redis server: 该命令将使用缺省参数
./src/redis-server
b)检查进程是否有Redis了：ps aux | grep redis，可以看见进程列表中有一个叫“src/redis-server”的进程了
- <span style="font-size:14px;">sounion@ubuntu:~/Desktop$ ps aux | grep redis
- sounion 65350 0.0 0.0 35024 1960 pts/1 Sl+ 07:28 0:00 ./src/redis-server
- sounion 65441 0.0 0.0 13584 916 pts/4 S+ 07:31 0:00 grep --color=auto redis
- </span>
c) 启动redis自带的客户端，进行测试：
# src/redis-cli -- 启动客户端并连接本地Redis
# set foo bar -- 提示 “ok”说明设置键值正常。
# get foo -- 能够提示返回正确的“bar”，说明运行正常。
# quit -- 退出客户端
- <span style="font-size:14px;">sounion@ubuntu:/usr/local/src/redis-2.6.16$ ./src/redis-cli
- redis 127.0.0.1:6379> set foo bar
- OK
- redis 127.0.0.1:6379> get foo
- "bar"
- redis 127.0.0.1:6379> quit
- </span>
d) 如果希望使用自己的 redis.conf 配置文件，可以使用如下命令：
./src/redis-server /path/to/redis.conf
e) 如果希望额外覆盖 redis.conf 配置文件中的某些参数，可以直接在命令行中使用参数：
./src/redis-server /etc/redis.conf --loglevel debug
./sr/redis-server --port 9999 --slaveof 127.0.0.1 6379
4. 开启多个redis 服务器实例
一台Redis服务器，分成多个节点，每个节点分配一个端口（6380，6381…），默认端口是6379。
如果已经开启了 一个redis 服务实例，再次执行 ./src/redis-server 会产生如下错误
- <span style="font-size:14px;">sounion@ubuntu:/usr/local/src/redis-2.6.16$ sudo ./src/redis-server
- [347] 19 Apr 07:47:00.859 # Warning: no config file specified, using the default config. In order to specify a config file use ./src/redis-server /path/to/redis.conf
- [347] 19 Apr 07:47:00.861 * Max number of open files set to 10032
- [347] 19 Apr 07:47:00.861 # Opening port 6379: bind: Address already in use
- </span>
每个节点对应一个Redis配置文件，如：redis6380.conf、redis6381.conf
cp redis.conf redis6380.conf
vi redis6380.conf
pidfile : pidfile/var/run/redis/redis_6380.pid
port 6380
logfile : logfile/var/log/redis/redis_6380.log
rdbfile : dbfilenamedump_6380.rdb
启动多个redis实例：
./src/redis-server /usr/local/redis/redis6380.conf
./src/redis-server /usr/local/redis/redis6381.conf
5、安装 redis-server
如果只是偶尔测试使用，可以使用 ./src/redis-server 方式直接启动。
但是如果是生产环境，需要进行 redis-server 安装部署。
命令：
cd /us/local/src/redis-2.6.16//utils
sudo ./install_server.sh
这个悲催的install_server.sh 命令必须在进入 utils 目录后再执行！
因为它的脚本写法以来一些相对目录路径！
- sounion@ubuntu:/usr/local/src/redis-2.6.16/utils$ sudo ./install_server.sh
- Welcome to the redis service installer
- This script will help you easily set up a running redis server
-
-
- Please select the redis port for this instance: [6379]
- Selecting default: 6379
- Please select the redis config file name [/etc/redis/6379.conf]
- Selected default - /etc/redis/6379.conf
- Please select the redis log file name [/var/log/redis_6379.log]
- Selected default - /var/log/redis_6379.log
- Please select the data directory for this instance [/var/lib/redis/6379]
- Selected default - /var/lib/redis/6379
- Please select the redis executable path [] /usr/local/src/redis-2.6.16/src/redis-server
- s#^port [0-9]{4}$#port 6379#;s#^logfile .+$#logfile /var/log/redis_6379.log#;s#^dir .+$#dir /var/lib/redis/6379#;s#^pidfile .+$#pidfile /var/run/redis_6379.pid#;s#^daemonize no$#daemonize yes#;
- Copied /tmp/6379.conf => /etc/init.d/redis_6379
- Installing service...
- update-rc.d: warning: /etc/init.d/redis_6379 missing LSB information
- update-rc.d: see <http:
- Adding system startup for /etc/init.d/redis_6379 ...

- /etc/rc4.d/S20redis_6379 -> ../init.d/redis_6379
- /etc/rc5.d/S20redis_6379 -> ../init.d/redis_6379
- Success!
- Starting Redis server...
- Installation successful!
6、添加到开机启动
如果进行了上述生产环境安装，则不再需要手动添加开机启动。
否则，需要修改
sudo vim /etc/rc.local
添加 /usr/local/src/redis-2.6.16/src/redis-server redis.conf
7、修改redis配置
如果 vm.overcommit_memory=0, 则在低内存状态时，后台redis 保存服务可能会失败。
需要修改配置文件/etc/sysctl.conf 添加 vm.overcommit_memory=1 然后重新启动使之生效。
刷新配置生效 sysctl vm.overcommit_memory=1
补充介绍
如果内存情况比较紧张的话，需要设定内核参数： /proc/sys/vm/overcommit_memory
这里说一下这个配置的含义：
/proc/sys/vm/overcommit_memory
该文件指定了内核针对内存分配的策略，其值可以是0、1、2。
0，表示内核将检查是否有足够的可用内存供应用进程使用；如果有足够的可用内存，内存申请允许；否则，内存申请失败，并把错误返回给应用进程。
1，表示内核允许分配所有的物理内存，而不管当前的内存状态如何。
2，表示内核允许分配超过所有物理内存和交换空间总和的内存
