redis是叁个NOSql数据库,在java web中,平时用来积攒session等,官方网址是

日前官方网址提议的安宁版本为3.2.6,下载地址为

1.下载redis

[root@iZ25ufmpy4sZ local]# wget http://download.redis.io/releases/redis-3.2.6.tar.gz

2.解压

[root@iZ25ufmpy4sZ local]# tar -xvf redis-3.2.6.tar.gz 

3.进入redis目录并make

[root@iZ25ufmpy4sZ local]# cd  redis-3.2.6
[root@iZ25ufmpy4sZ redis-3.2.6]# ls

(cd ../deps && make distclean)
make[2]: Entering directory `/usr/local/redis-3.2.6/deps'
make[1]: Leaving directory `/usr/local/redis-3.2.6/src'

4.进入src目录make install

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

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install

5.那个时候开始,只要运转scr目录下的redis-server,不过不切合Linux处理,提议在Nginx根目录下开创多个bin和etc来分别寄存系统文件和构造文件,如下

图片 1图片 2

[root@iZ25ufmpy4sZ redis-3.2.6]# pwd
/usr/local/redis-3.2.6
[root@iZ25ufmpy4sZ redis-3.2.6]# mkdir bin
[root@iZ25ufmpy4sZ redis-3.2.6]# mkdir etc
[root@iZ25ufmpy4sZ redis-3.2.6]# ls
00-RELEASENOTES  bin  BUGS  CONTRIBUTING  COPYING  deps  etc  INSTALL  Makefile  MANIFESTO  README.md  redis.conf  runtest  runtest-cluster  runtest-sentinel  sentinel.conf  src  tests  utils

6.copy对应文件到bin和etc目录下

7.改变配置文件redis.cnf,把品质daemonize改为yes

# Close the connection after a client is idle for N seconds (0 to disable)
timeout 0

# TCP keepalive.
#
# If non-zero, use SO_KEEPALIVE to send TCP ACKs to clients in absence
# of communication. This is useful for two reasons:
#
# 1) Detect dead peers.
# 2) Take the connection alive from the point of view of network
#    equipment in the middle.
#
# On Linux, the specified value (in seconds) is the period used to send ACKs.
# Note that to close the connection the double of the time is needed.
# On other kernels the period depends on the kernel configuration.
#
# A reasonable value for this option is 300 seconds, which is the new
# Redis default starting with Redis 3.2.1.
tcp-keepalive 300

################################# GENERAL #####################################

# 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 yes

# If you run Redis from upstart or systemd, Redis can interact with your
# supervision tree. Options:
#   supervised no      - no supervision interaction
#   supervised upstart - signal upstart by putting Redis into SIGSTOP mode
#   supervised systemd - signal systemd by writing READY=1 to $NOTIFY_SOCKET
#   supervised auto    - detect upstart or systemd method based on
#                        UPSTART_JOB or NOTIFY_SOCKET environment variables
# Note: these supervision methods only signal "process is ready."
#       They do not enable continuous liveness pings back to your supervisor.
supervised 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

 

8.启动redis

[root@iZ25ufmpy4sZ bin]# ./redis-server ../etc/redis.conf

9.假诺照旧认为麻烦,能够在redis根目录创立五个剧本,start.sh和stop.sh,内容分别如下

[root@iZ25ufmpy4sZ redis]# ls
00-RELEASENOTES  bin  BUGS  CONTRIBUTING  COPYING  deps  dump.rdb  etc  INSTALL  Makefile  MANIFESTO  README.md  redis.conf  runtest  runtest-cluster  runtest-sentinel  sentinel.conf  src  start.sh  stop.sh  tests  utils
[root@iZ25ufmpy4sZ redis]# cat start.sh 
/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
[root@iZ25ufmpy4sZ redis]# cat stop.sh 
/usr/local/redis/bin/redis-cli shutdown
