centos7安装redis的步骤说明
- 安装gcc环境:
yum install gcc
- 安装wget环境:
yum -y install wget
- 官方下载redis包:
wget http://download.redis.io/releases/redis-3.2.3.tar.gz $ tar xzf redis-3.2.3.tar.gz
- 进入redis目录 编译安装
cd redis-3.2.3
make
- 执行安装命令
make install
make install安装完成后,会在/usr/local/bin目录下生成下面几个可执行文件,它们的作用分别是:
redis-server:Redis服务器端启动程序
redis-cli:Redis客户端操作工具。也可以用telnet根据其纯文本协议来操作
redis-benchmark:Redis性能测试工具
redis-check-aof:数据修复工具
redis-check-dump:检查导出工具
- 配置redis
cp redis.conf /etc/ 6379.conf
修改配置文件6379.conf
vi /etc/6379.conf
(1)修改daemonize配置项为yes(大概在128行),使Redis进程在后台运行
daemonize yes
(2)注释 bind 127.0.0.1 (取消限制ip)
#bind 127.0.0.1
(3)设置密码
将”# requirepass foobared“ 取掉注释改成 requirepass 123
(4)关闭防火墙
service firewalld stop
- 启动redis
cd /usr/local/bin
./redis-server /etc/6379.conf
- 检查启动情况
ps -ef | grep redis
- 添加开机启动项
(1)编写脚本
vi /etc/init.d/redis
#!/bin/sh
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/etc/${REDISPORT}.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
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE does not exist, process is not running"
else
PID=$(cat $PIDFILE)
echo "Stopping ..."
$CLIEXEC -a "123" -p $REDISPORT shutdown
while [ -x /proc/${PID} ]
do
echo "Waiting for Redis to shutdown ..."
sleep 1
done
echo "Redis stopped"
fi
;;
*)
echo "Please use start or stop as first argument"
;;
esac
(2)保存退出,设置权限
chmod 777 /etc/init.d/redis
- 启动redis
打开redis命令:service redis start
关闭redis命令:service redis stop
设为开机启动:chkconfig redis on
设为开机关闭:chkconfig redis off
