Centos Linux 系统部署java程序(四、Redis的安装和部署)

安装

安装非常简单，执行以下命令即可

[root@hcss-ecs-5eee labsys]# yum install -y redis

配置

常用的配置是3个地方，当然不常用的配置还有很多，后续将会把使用的心得体会总结成长篇文章让大家知道得更详细，目前我们只讲这3个基本的。

配置文件默认是 /etc/redis.conf

端口配置端口号默认为6379。如需要修改，则在配置文件中找到port所在的位置,将port后的默认端口6379修改为你想要的端口号即可。

# Accept connections on the specified port, default is 6379 (IANA #815344).
# If port 0 is specified Redis will not listen on a TCP socket.
port 6379

密码配置默认是不使用密码的，如果需要认证密码，则在配置文件中找到requirepass的配置，手动增加一项，对应的值填上想要设置的密码，配置就改好了。

################################## SECURITY ###################################

# Require clients to issue AUTH <PASSWORD> before processing any other
# commands.  This might be useful in environments in which you do not trust
# others with access to the host running redis-server.
#
# This should stay commented out for backward compatibility and because most
# people do not need auth (e.g. they run their own servers).
#
# Warning: since Redis is pretty fast an outside user can try up to
# 150k passwords per second against a good box. This means that you should
# use a very strong password otherwise it will be very easy to break.
#
requirepass abc@123

IP绑定配置 redis为了控制访问安全，设置了ip绑定，默认绑定的IP是127.0.0.1 ，也可以改为本机上其他网卡的地址，绑定之后，就只能通过该网卡的IP来访问。也可以不设置该项，那么所有的能连上网的主机都能访问。

配置如下：

################################## NETWORK #####################################

# 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 ::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 loopback 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
