二、启动redis的三种方式
先切换到redis src目录下
1
2 1[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src
2
1、直接启动redis
./redis-server

如上图:redis启动成功,但是这种启动方式需要一直打开窗口,不能进行其他操作,不太方便。
按 ctrl + c可以关闭窗口。
2、以后台进程方式启动redis
第一步:修改redis.conf文件
将
1
2 1daemonize no
2
修改为
1
2 1daemonize yes
2
第二步:指定redis.conf文件启动
1 | ./redis-server /usr/local/redis-4.0.6/redis.conf |
1 | 1 |
1
2
3
4
5 1[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server /usr/local/redis-4.0.6/redis.conf
218713:C 13 Dec 13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
318713:C 13 Dec 13:07:41.109 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started
418713:C 13 Dec 13:07:41.109 # Configuration loaded
5
第三步:关闭redis进程
首先使用ps -aux | grep redis查看redis进程
1
2
3
4 1[root@iZwz991stxdwj560bfmadtZ src]# ps -aux | grep redis
2root 18714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-server 127.0.0.1:6379
3root 18719 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis
4
使用kill命令杀死进程
1
2 1[root@iZwz991stxdwj560bfmadtZ src]# kill -9 18714
2
3、设置redis开机自启动
1、在/etc目录下新建redis目录
mkdir redis
1
2 1[root@iZwz991stxdwj560bfmadtZ etc]# mkdir redis
2
2、将/usr/local/redis-4.0.6/redis.conf 文件复制一份到/etc/redis目录下,并命名为6379.conf
1
2 1[root@iZwz991stxdwj560bfmadtZ redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf
2
3、将redis的启动脚本复制一份放到/etc/init.d目录下
1
2 1[root@iZwz991stxdwj560bfmadtZ init.d]# cp /usr/local/redis-4.0.6/utils/redis_init_script /etc/init.d/redisd
2
4、设置redis开机自启动
先切换到/etc/init.d目录下
然后执行自启命令
1
2
3 1[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
2service redisd does not support chkconfig
3
看结果是redisd不支持chkconfig
解决方法:
使用vim编辑redisd文件,在第一行加入如下两行注释,保存退出
1
2
3 1# chkconfig: 2345 90 10
2# description: Redis is a persistent key-value database
3
注释的意思是,redis服务必须在运行级2,3,4,5下被启动或关闭,启动的优先级是90,关闭的优先级是10。
再次执行开机自启命令,成功
1
2 1[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
2
现在可以直接已服务的形式启动和关闭redis了
启动:
service redisd start
1
2
3
4
5
6 1[root@izwz991stxdwj560bfmadtz ~]# service redisd start
2Starting Redis server...
32288:C 13 Dec 13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
42288:C 13 Dec 13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started
52288:C 13 Dec 13:51:38.087 # Configuration loaded
6
关闭:
service redisd stop
1
2
3
4 1[root@izwz991stxdwj560bfmadtz ~]# service redisd stop
2Stopping ...
3Redis stopped
4
修改redis访问IP和密码:
vim配置文件redis.conf
1.将bind 127.0.0.1中的IP更改成你需要访问的IP,如果不更改就默认为本地访问。
2.requirepass取消注释,替换foobared就是你要修改的值:
改为:
3.使用redis-cli访问本地redis服务:
-h:IP
-p:端口
1
2 1[root@admin src]# redis-cli -h 127.0.0.1 -p 6379
2
输入密码:
1
2
3
4 1127.0.0.1:6379> AUTH "test123"
2
3OK
4
查看密码:
1
2
3
4 1127.0.0.1:6379> config get requirepass
21) "requirepass"
32) "test123"
4
这时可以看到redis输出了我们一开始设置的密码test123,这样密码就设置成功了!
