Redis安装

 1、安装tcl8.6

tcl官网：http://www.linuxfromscratch.org/blfs/view/cvs/general/tcl.html

可以从官网获取tcl的最新版本，官网也有详细的安装步骤

# wget http://downloads.sourceforge.net/tcl/tcl8.6.0-src.tar.gz
# tar xf tcl8.6.0-src.tar.gz
# cd tcl8.6.0/unix/
# ./configure --prefix=/usr \
            --mandir=/usr/share/man \
            $([ $(uname -m) = x86_64 ] && echo --enable-64bit) &&
make &&
sed -e "s@^\(TCL_SRC_DIR='\).*@\1/usr/include'@" \
    -e "/TCL_B/s@='\(-L\)\?.*unix@='\1/usr/lib@" \
    -i tclConfig.sh

# make test
# make install && make install-private-headers && ln -v -sf tclsh8.6 /usr/bin/tclsh && chmod -v 755 /usr/lib/libtcl8.6.so
# tclsh8.6  //有这个命令表示安装成功

2、安装redis

redis官网：http://redis.io/

# tar xf redis-2.6.2.tar.gz
# cd redis-2.6.2
# make
# make test
# make install
# cp redis.conf /etc/
# vi /etc/sysctl.conf //如果已经配置过这里了，可以忽略，如果没有，一定要配置 vm.overcommit_memory = 1
# redis-server /etc/redis.conf

# netstat -nutlp | grep 6379 | grep -v grep //看到以下表示redis启动成功
6379          0.0.0.0:*               LISTEN      14845/xinetd

3、编写Redis的服务管理脚本

# vi /etc/init.d/redis

#!/bin/bash
# Init file for redis
# chkconfig: - 80 12
# description: redis daemon
# processname: redis
# TITLE END
# Source function library.
. /etc/rc.d/init.d/functions

BIN="/usr/local/bin"
CONFIG="/etc/redis.conf"
PIDFILE="/var/run/redis.pid"
prog="redis-server"
desc="Redis Server"
start() {
        if [ -e $PIDFILE ];then
             echo "$desc already running...."
             exit 1
        fi
        echo -n $"Starting $desc: "
        daemon $BIN/$prog $CONFIG
        RETVAL=$?
        echo
        [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog
        return $RETVAL
}
stop() {
        echo -n $"Stop $desc: "
        killproc $prog
        RETVAL=$?
        echo
        [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$prog $PIDFILE
        return $RETVAL
}
restart() {
        stop
        start
}
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  restart)
        restart
        ;;
  status)
        status $prog
        RETVAL=$?
        ;;
   *)
        echo $"Usage: $0 {start|stop|restart|condrestart|status}"
        RETVAL=1
esac
exit $RETVAL

4、设置Redis开机启动

# chmod 755 /etc/init.d/redis
# chkconfig --add redis
# chkconfig --level 345 redis on
# chkconfig --list redis

5、Redis的日志配置

redis默认会把日志打印到屏幕上，并且不是以daemon的模式运行，可以改下配置文件

 

# vi /etc/redis.conf
#daemonize no   //默认为no，注释掉，新增一行改为yes
daemonize yes

# Set server verbosity to 'debug'
# it 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   //这里定义日志的级别，默认为notice

#logfile stdout    //这里指定Redis的日志文件位置
logfile /var/log/redis.log

配置完成后，重启下Redis，看一下Redis的日志吧

[root@node3 ~]# cat /var/log/redis.log
[3779] 07 Apr 12:23:42.340 * Max number of open files set to 10032
                _._
           _.-``__ ''-._
      _.-``    `.  `_.  ''-._           Redis 2.6.2 (00000000/0) 64 bit
  .-`` .-```.  ```\/    _.,_ ''-._
 (    '      ,       .-`  | `,    )     Running in stand alone mode

  `-._    `-._  `-./  _.-'    _.-'
 |`-._`-._    `-.__.-'    _.-'_.-'|
 |    `-._`-._        _.-'_.-'    |           http://redis.io

 |    `-._`-._        _.-'_.-'    |
  `-._    `-._`-.__.-'_.-'    _.-'
      `-._    `-.__.-'    _.-'
          `-._        _.-'
              `-.__.-'

[3779] 07 Apr 12:23:42.344 # Server started, Redis version 2.6.2
[3779] 07 Apr 12:23:42.344 * The server is now ready to accept connections on port 6379

OK,到此基本配置已经配置完成

6、Redis的状态信息

Redis有一个命令，可以查看当前redis的状态信息，非常的全面

运行redis-cli info

[root@node3 ~]# redis-cli info

详细的先不解释了， 等有空再解释吧。

 7、安装Redis的WEB管理工具phpRedisAdmin

# yum install git
# git clone https://github.com/ErikDubbelboer/phpRedisAdmin.git
# cd phpRedisAdmin
# git submodule init
# git submodule update

 然后访问
