2.解压文件

[root@zhangmeng ~]# tar xf redis-3.2..tar.gz
[root@zhangmeng ~]#
[root@zhangmeng ~]# ll
total
-rw-------.  root root         Jun  : anaconda-ks.cfg

drwxrwxr-x.  root root        Jul  : redis-3.2.
-rw-r--r--.  root root     Jul  : redis-3.2..tar.gz

3.编译及安装

[root@zhangmeng ~]# cd redis-3.2.
[root@zhangmeng redis-3.2.]# make && make install
cd src && make all
make[]: Entering directory `/root/redis-3.2./src'
rm -rf redis-server redis-sentinel redis-cli redis-benchmark redis-check-rdb redis-check-aof *.o *.gcda *.gcno *.gcov redis.info lcov-html

make[]: *** [adlist.o] Error
make[]: Leaving directory `/root/redis-3.2./src'
make: *** [all] Error
[root@zhangmeng redis-3.2.]# 

4.上面报错：

make[3]: gcc: Command not found

/bin/sh: cc: command not found

是由于系统没有安装gcc

安装gcc：yum -y install gcc

5.重新编译安装，还是报错

[root@zhangmeng redis-3.2.]# make && make install
cd src && make all
make[]: Entering directory `/root/redis-3.2./src'
    CC adlist.o
In file included from adlist.c::
zmalloc.h::: error: jemalloc/jemalloc.h: No such file or directory
zmalloc.h::: error: #error "Newer version of jemalloc required"
make[]: *** [adlist.o] Error
make[]: Leaving directory `/root/redis-3.2./src'
make: *** [all] Error 

6.上网查了一下，将make改为make MALLOC=libc，推测是因为编译库的问题。

    [root@zhangmeng redis-3.2.10]# make MALLOC=libc
　　......
　  CC crc64.o
    CC bitops.o
    CC sentinel.o
    CC notify.o

    LINK redis-benchmark
    INSTALL redis-check-rdb
    CC redis-check-aof.o
    LINK redis-check-aof

Hint: It's a good idea to run 'make test' ;)

make[]: Leaving directory `/root/redis-3.2./src'
[root@zhangmeng redis-3.2.]# 

7.make完成之后,进行install,默认安装路径为/usr/local/bin下,这里我们把他安装目录放到/usr/local/redis下,使用PREFIX指定目录

[root@zhangmeng redis-3.2.]# mkdir /usr/local/redis
[root@zhangmeng redis-3.2.]# make PREFIX=/usr/local/redis install
cd src && make install
make[]: Entering directory `/root/redis-3.2./src'

Hint: It's a good idea to run 'make test' ;)

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
make[]: Leaving directory `/root/redis-3.2./src'
[root@zhangmeng redis-3.2.]# 

8.将redis可执行目录添加到环境变量中,编辑~/.bash_profile添加redis环境变量

[root@zhangmeng redis-3.2.]# vi ~/.bash_profile
[root@zhangmeng redis-3.2.]#
[root@zhangmeng redis-3.2.]# cat ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=/usr/local/redis/bin:$PATH:$HOME/bin

export PATH
[root@zhangmeng redis-3.2.]# 

9.拷贝redis.conf文件到/etc下

[root@zhangmeng redis-3.2.]# cp redis.conf /etc/

10.查看redis参数

[root@zhangmeng redis-3.2.]# redis-server --help
Usage: ./redis-server [/path/to/redis.conf] [options]
       ./redis-server - (read config from stdin)
       ./redis-server -v or --version
       ./redis-server -h or --help
       ./redis-server --test-memory <megabytes>

Examples:
       ./redis-server (run the server with default conf)
       ./redis-server /etc/redis/.conf
       ./redis-server --port
       ./redis-server --port  --slaveof 127.0.0.1
       ./redis-server /etc/myredis.conf --loglevel verbose

Sentinel mode:
       ./redis-server /etc/sentinel.conf --sentinel
[root@zhangmeng redis-3.2.]# 

11.版本查看

[root@zhangmeng redis-3.2.10]# redis-server -v
Redis server v=3.2.10 sha=00000000:0 malloc=libc bits=64 build=a60a764624df1665

12.启动redis服务

[root@zhangmeng redis-3.2.]# redis-server /etc/redis.conf

13.测试启动 redis-cli ping 返回PONG，启动成功。

[root@zhangmeng ~]# redis-cli ping
PONG
[root@zhangmeng ~]#
[root@zhangmeng ~]# netstat -tulnp |grep

14.关闭redis服务（备注：可指定端口:redis-cli -p <port> shutdown）

[root@zhangmeng ~]# redis-cli shutdown
[root@zhangmeng ~]#
[root@zhangmeng ~]# netstat -tulnp |grep
[root@zhangmeng ~]#

15.连接redis，下面的提示是因为刚才我们把redis关了（连接redis的两种方法见http://www.cnblogs.com/xphdbky/p/7405825.html）
