CentOS7安装redis

CentOS7安装redis和mongodb

本文介绍在CentOS7上安装redis数据库。

系统配置信息如下：

 

[linus@localhost ~]$ uname -r
3.10.0-229.20.1.el7.x86_64
[linus@localhost ~]$ more /etc/redhat-release 
CentOS Linux release 7.1.1503 (Core) 
[linus@localhost ~]$ 

 

 

Redis

1、下载Redis，当前最新版本是3.0.5，然后安装。

 

[linus@localhost redis]$ wget http://download.redis.io/releases/redis-3.0.5.tar.gz

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

 然后执行make test进行验证，报如下错误，安装tcl之后就可以正常执行了：

 

 

[linus@localhost redis-3.0.5]$ make test
cd src && make test

 安装完成后，可以切换src目录下，执行redis-server命令启动redis服务器：

此时可以通过redis-cli命令连接该redis服务器，并且可以通过SHUTDOWN命令关闭服务器：

服务器端会打印：

8921:M 24 Nov 13:46:52.838 * Saving the final RDB snapshot before exiting.

8921:M 24 Nov 13:46:52.844 # Redis is now ready to exit, bye bye...

 服务器端配置：

 

最关键的配置以下选项：

 

# 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
# Specify the server verbosity level.
# This can be one of:
# debug (a lot of information, useful for development/testing)
# verbose (many rarely useful info, but not a mess like the debug level)
# notice (moderately verbose, what you want in production probably)
# warning (only very important / critical messages are logged)
loglevel notice
# Specify the log file name. Also the empty string can be used to force
# Redis to log on the standard output. Note that if you use standard
# output for logging but daemonize, logs will be sent to /dev/null
logfile /var/log/redis.log
# The working directory.
#
# The DB will be written inside this directory, with the filename specified
# above using the 'dbfilename' configuration directive.
#
# The Append Only File will also be created inside this directory.
#
# Note that you must specify a directory here, not a file name.
dir ./

 

添加启动脚本/etc/init.d/redis：

 

#!/bin/sh
#
# redis        Startup script for Redis Server
#
# chkconfig: - 90 10
# description: Redis is an open source, advanced key-value store. 
#
# processname: redis-server
# config: /etc/redis.conf
# pidfile: /var/run/redis.pid
 
REDISPORT=6379
# 下面的目录要看编译的目录，这两个文件会在编译目录的src目录下。
EXEC=/usr/local/bin/redis-server
REDIS_CLI=/usr/local/bin/redis-cli
 
PIDFILE=/var/run/redis.pid
# 下面的目录要看编译的目录，这个文件会在编译目录下。
CONF="/usr/src/redis-2.8.13/redis.conf"
 
case "$1" in
    start)
        if [ -f $PIDFILE ]
        then
                echo "$PIDFILE exists, process is already running or crashed"
        else
                echo "Starting Redis server..."
                $EXEC $CONF
        fi
        if [ "$?"="0" ] 
        then 
              echo "Redis is running..."
        fi 
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $REDIS_CLI -p $REDISPORT SHUTDOWN
                while [ -x ${PIDFILE} ]
               do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
   restart|force-reload)
        ${0} stop
        ${0} start
        ;;
  *)
    echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
        exit 1
esac

 

添加redis为系统的服务：

[root@localhost redis]# ll /etc/init.d/redis 
-rw-r--r--. 1 root root 1394 Nov 24 14:06 /etc/init.d/redis
[root@localhost redis]# chmod +x /etc/init.d/redis 
[root@localhost redis]# ll /etc/init.d/redis 
-rwxr-xr-x. 1 root root 1394 Nov 24 14:06 /etc/init.d/redis
[root@localhost redis]# 
[root@localhost redis]# chkconfig --add redis
[root@localhost redis]# chkconfig redis on
[root@localhost redis]# chkconfig 

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

netconsole     	0:off	1:off	2:off	3:off	4:off	5:off	6:off
network        	0:off	1:off	2:on	3:on	4:on	5:on	6:off
redis          	0:off	1:off	2:on	3:on	4:on	5:on	6:off
[root@localhost redis]# 

 ok，现在就安装好了。启动redis使用service redis start 或者/etc/init.d/redis start ，停止redis的命令service redis stop 或者/etc/init.d/redis stop。
