在CentOS上装Redis

Redis官网

$ wget http://download.redis.io/releases/redis-3.2.5.tar.gz
$ tar xzf redis-3.2.5.tar.gz
$ cd redis-3.2.5
$ make

执行第一行命令就出错了

-bash: wget: 未找到命令

原因是CentOS最小化安装没有装wget,使用下面命令安装即可:

yum -y install wget

然后往下执行,在make的时候又报错了:

cd src && make all
make[1]: 进入目录“/usr/soft/redis-3.2.5/src”
    CC adlist.o
/bin/sh: cc: 未找到命令
make[1]: *** [adlist.o] 错误 127
make[1]: 离开目录“/usr/soft/redis-3.2.5/src”
make: *** [all] 错误 2

原因是虚拟机系统中缺少gcc,安装一下gcc:

yum -y install gcc automake autoconf libtool make

重新make redis ,发现又报错了:

cd src && make all
make[1]: 进入目录“/usr/soft/redis-3.2.5/src”
    CC adlist.o
In file included from adlist.c:34:0:
zmalloc.h:50:31: 致命错误:jemalloc/jemalloc.h:没有那个文件或目录
 #include <jemalloc/jemalloc.h>
                               ^
编译中断。
make[1]: *** [adlist.o] 错误 1
make[1]: 离开目录“/usr/soft/redis-3.2.5/src”
make: *** [all] 错误 2

解决方法:

make MALLOC=libc

这样就顺利安装了,接下来运行:

src/redis-server

设置防火墙(没开启防火墙的可以跳过):

firewall-cmd --zone=public --add-port=6379/tcp --permanent
firewall-cmd --reload 

 

接下来就可以测试了,结果在windows中测试的时候发现连接不上,原来是redis默认绑定监听:

# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 127.0.0.1

注释掉,还有这里:

# 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

把yes改成no,再次运行

src/redis-server

从Windows测试,测试代码如下:

string redisIP = ConfigurationManager.AppSettings["redisIP"];
            try
            {
                ConnectionMultiplexer redis = ConnectionMultiplexer.Connect(redisIP);
                IDatabase db = redis.GetDatabase();
                string value = "abcdefg";
                db.StringSet("mykey", value);
                string value1 = db.StringGet("mykey");
                Console.WriteLine(value1);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

这里用的是StackExchange.Redis,用包管理器就可以安装:

Install-Package StackExchange.Redis

运行程序,发现还是连接不上,什么问题呢?再仔细看下redis的提示:

2599:C 11 Nov 01:34:54.682 # Warning: no config file specified, using the default config. In order to specify a config file use src/redis-server /path/to/redis.conf

也就是说我们上面修改的配置redis没有使用,接下来改下命令

src/redis-server redis.conf

这样就可以使用我们自己的配置了,再次连接,OK了。
