linux上安装redis4.0.9

redis安装从3.0的版本到现在4.0的版本，现在装一个4.0的版本供大家学习使用。

先yum安装gcc

 yum -y install gcc

开始编译安装

tar -xvf redis-4.0.9.tar.gz
cd redis-4.0.9/
make MALLOC=libc

　继续中...............

[root@localhost redis-4.0.9]# cd src && make install
    CC Makefile.dep

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

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install

安装好了，启动试试。

　这种方式退出就服务就停了，所以让它在后台运行可以这样做：

第一种:直接在启动服务后面加上 & 符号，让它在后台运行。

　第二种：修改redis.conf配置文件

#daemonize no
daemonize yes

启动服务

src/redis-server redis.conf 

36443:C 20 Apr 15:33:12.897 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 36443:C 20 Apr 15:33:12.898 # Redis version=4.0.9, bits=64, commit=00000000, modified=0, pid=36443, just started 36443:C 20 Apr 15:33:12.898 # Configuration loaded

　查看服务是否启动

ps -ef |grep redis
root      36412   5190  0 15:28 pts/1    00:00:00 src/redis-server 127.0.0.1:6379
root      36417   5190  0 15:28 pts/1    00:00:00 grep --color=auto redis

　停止redis服务

kill -9 进程号

　设置redis登陆密码

vim redis.conf
修改成下面内容即可
# requirepass foobared
requirepass 123456

　此时重启redis，登陆时需要密码验证

[root@localhost redis-4.0.9]# src/redis-server redis.conf
36516:C 20 Apr 15:42:02.221 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
36516:C 20 Apr 15:42:02.221 # Redis version=4.0.9, bits=64, commit=00000000, modified=0, pid=36516, just started
36516:C 20 Apr 15:42:02.221 # Configuration loaded
[root@localhost redis-4.0.9]# src/redis-cli

　　好了，这就是简单的redis部署环境了，生产环境其实一样，没什么复杂的，配置好了，然后就把ip和端口告诉开发，开发就会去连接redis，或者写到配置文件中，最后将整个的包发给我们运维，让我们去部署就行了，非常简单。
