linux下安装redis与启动,及后台启动redis

1.将下载好的压缩包放到/usr/local目录下

# tar xzf redis-3.0.
# cd redis-3.0.2
# make
提示错误 make: cc: Command not found make: *** [adlist.o] Error 127
没有安装gcc环境，需要安装gcc
# yum install gcc
安装后检查是否安装成功
# rpm -qa |grep gcc
之后重新make

2.编译完成后，在Src目录下，有四个可执行文件redis-server、redis-benchmark、redis-cli和f将其拷贝到一个目录下。

# mkdir /usr/redis
# cp redis-server  /usr/redis
# cp redis-benchmark /usr/redis
# cp redis-cli  /usr/redis
# f  /usr/redis
# cd /usr/redis

3.启动服务

# redis-server   f
提示错误 -bash :redis-server:command not found建立软连接
# ln -s /usr/redis/redis-server /usr/bin/redis-server
# ln -s /usr/redis/redis-cli /usr/bin/redis-cli
重新启动
# redis-server /usr/f

4.设置开机自启动

• 先将f中daemonize设置为yes,确保守护进程开启。
• 编写开机自启动脚本
  • #vi /etc/init.d/redis

PATH=/usr/local/bin:/sbin:/usr/bin:/bin   
REDISPORT=6379  
EXEC=/usr/redis/redis-server   
REDIS_CLI=/usr/redis/redis-cli   PIDFILE=/var/run/redis.pid   
CONF="/usr/f"  
AUTH="1234"  case "$1" in   start)   if [ -f $PIDFILE ]   then   echo "$PIDFILE exists, process is already running or crashed."  else  echo "Starting "  $EXEC $CONF   fi   if [ "$?"="0" ]   then   echo "Redis "  fi   ;;   stop)   if [ ! -f $PIDFILE ]   then   echo "$PIDFILE exists, process is not running."  else  PID=$(cat $PIDFILE)   echo &#"  $REDIS_CLI -p $REDISPORT  SHUTDOWN    sleep 2  while [ -x $PIDFILE ]   do  echo "Waiting for Redis "  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

注： redis设置AUTH命令

redis 127.0.0.1:6379> AUTH PASSWORD
(error) ERR Client sent AUTH, but no password is set
redis 127.0.0.1:6379> CONFIG SET requirepass "1234"
OK
redis 127.0.0.1:6379> AUTH 1234
Ok

• 设置权限

chmod 755 redis

• 启动

# /etc/init.d/redis start  
提示错误 /etc/init.d/redis:permission denied# chmod a+x /etc/init.d/redis
a+x 是给所有人加上可执行权限，包括所有者，所属组，和其他人
o+x 只是给其他人加上可执行权限重新启动后显示
Starting  
Redis is running ...

• 设置开机自启动

# chkconfig redis on
提示错误 service redis does not support chkconfig把下面两行注释放在/etc/init.d/redis文件靠前的注释中：
# chkconfig:   2345 90 10# description:  Redis is a persistent key-value database

• 关机重启测试
