linux非root用户安装4.0.14版本redis

　　先到官网https://redis.io/download下安装包，现在最新是5.0.5版本，可惜点击下载后被windows禁了，那就下4版本的，往下看Other versions的Old(4.0)，点4版本最新4.0.14：

　　redis的优点之一就是安装包特别小，很快就能下好，点个赞。接下来进入linux的wlf用户，通过rz上传至soft目录，开始执行安装操作：

$ tar xzvf soft/redis-4.0..tar.gz
$ cd redis-4.0.
$ make

　　make构建结束后，也就安装结束了：

    LINK redis-server
    INSTALL redis-sentinel
    CC redis-cli.o
    LINK redis-cli
    CC redis-benchmark.o
    LINK redis-benchmark
    INSTALL redis-check-rdb
    INSTALL redis-check-aof

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

make[]: Leaving directory `/home/wlf/redis-4.0./src'

　　启动redis前我们用vi改下配置文件redis.conf：

# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all the network interfaces available on the server.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only into
# the IPv4 lookback interface address (this means Redis will be able to
# accept connections only from clients running into the same computer it
# is running).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 127.0.0.1

# Protected mode is a layer of security protection, in order to avoid that
# Redis instances left open on the internet are accessed and exploited.
#
# When protected mode is on and if:
#
# ) The server is not binding explicitly to a set of addresses using the
#    "bind" directive.
# ) No password is configured.
#
# The server only accepts connections from clients connecting from the
# IPv4 and IPv6 loopback addresses 127.0.0.1 and ::, and from Unix domain
# sockets.
#
# By default protected mode is enabled. You should disable it only if
# you are sure you want clients from other hosts to connect to Redis
# even if no authentication is configured, nor a specific set of interfaces
# are explicitly listed using the "bind" directive.
protected-mode yes

　　在bind 127.0.0.1前加#注掉，将protected-mode yes改为protected-mode no去掉保护策略，这样就能支持远程连接了。

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize no

# If a pid file is specified, Redis writes it where specified at startup
# and removes it at exit.
#
# When the server runs non daemonized, no pid file is created if none is
# specified in the configuration. When the server is daemonized, the pid file
# is used even if not specified, defaulting to "/var/run/redis.pid".
#
# Creating a pid file is best effort: if Redis is not able to create it
# nothing bad happens, the server will start and run normally.
pidfile /var/run/redis_6379.pid

　　默认redis不是在后台运行的，将daemonize no改为daemonize yes，另外当后台运行时默认生成的pid文件是在/var/run目录下，我们可以指定为自己的目录，如改为/home/wlf/redis-4.0.14/run/redis_6379.pid

　　保存好后启动redis：

$ src/redis-server redis.conf
:C  Sep ::56.153 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
:C  Sep ::56.153 # Redis version=4.0., bits=, commit=, modified=, pid=, just started
:C  Sep ::56.153 # Configuration loaded

　　看下进程，已经起来了：

$ netstat -nlp | grep
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp               0.0.0.0:            0.0.0.0:*               LISTEN      /src/redis-ser
tcp6              :::                 :::*                    LISTEN      /src/redis-ser

　　我们克隆会话打开另一个窗口，进入wlf用户开启客户端：

$ cd redis-4.0./
$ src/redis-cli
127.0.0.1:> set wlf wumanshu
OK
127.0.0.1:> get wlf
"wumanshu"

　　如果我们想从客户端远程连接服务端，只需指定服务端ip即可，假如redis服务端ip是10.110.1.11，那么我在客户端机器使用命令需要加参数h（默认端口也是6379）：

$ src/redis-cli -h 10.110.1.11

　　关闭客户端，同时也将关闭服务端：

$ src/redis-cli shutdown
$ netstat -nlp | grep
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

　　或者使用telnet也可以从远程机器连接到redis。不过因为以上设置，redis本身的安全机制已经荡然无存，此时很容被入侵，具体方法和安全防护措施参见redis支持远程接入的安全防护问题。
