Redis开源代码读书笔记零（Ubuntu14.04 64位安装）

Redis代码可以在Linux, OSX, OpenBSD, NetBSD, FreeBSD系统上进行部署，并且支持大小端CPU类型。学习环境采用了一台Ubuntu14.04 64位的系统，所有代码的学习是基于redis-3.0.7。

请从Redis官网http://redis.io，下载redis-3.0.7.tar.gz源代码

Redis代码编译

32位，64bit的系统需要安装32位系统的一些支持库

# apt-get install libc6-dev-i386 g++-multilib
# make distclean
# make 32bit

64位，64bit的系统，所以一把过。

# tar -zxvf  redis-3.0.7.tar.gz
# cd  redis-3.0.7
# make
# make test

Redis安装

这里我们学习和测试使用的是64位结果。直接进行安装，这里都采用默认配置。

# make install

cd utils
./install_server.sh
Welcome to the redis service installer
This script will help you easily set up a running redis server

You must run this script as root. Sorry!
daniel@ubuntu:~/redis-3.0.7/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/bin/redis-server]
Selected config:
Port           : 6379
Config file    : /etc/redis/6379.conf
Log file       : /var/log/redis_6379.log
Data dir       : /var/lib/redis/6379
Executable     : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379

/etc/rc5.d/S20redis_6379 -> ../init.d/redis_6379
Success!
Starting Redis server...
Installation successful!

安装完成后，可以使用redis_6379脚本进行启动redis服务。当然如果需要每次随机启动redis，可以将以下脚本增加到rc.local等脚本中。

/etc/init.d/redis_6379

命令行客户端

服务启动后，可以采用redis-cli进行连接

% cd src
% redis-cli
redis> ping
PONG
redis> set foo bar
OK
redis> get foo
"bar"
redis> incr mycounter
(integer) 1
redis> incr mycounter
(integer) 2
redis>

其他注意事项

==》glibc, jemalloc, tcmalloc编译配置, make时添加MALLOC宏，默认是glibc，比如"make MALLOC=libc"

==》更多的编译输出，make时添加V宏，比如"make V=1"

==》自定义配置启动，比如"redis-server /path/to/redis.conf"

==》主从配置，比如"redis-server --port 9999 --slaveof 127.0.0.1 6379"

==》运行日志记录级别定义，比如"redis-server /etc/redis/6379.conf --loglevel debug"
