Configure the Redis boot startup script under Centos

1. Download and install

wget http://redis.googlecode.com/files/redis-2.2.13.tar.gz 
tar -zxf redis-2.2.13.tar.gz 
cd redis-2.2.13 
make 
sudo make install  
cp redis.conf /etc 

At install, the redis command is copied under /usr/local/bin

2. Set up user and log directory

Before starting Redis for the first time, it is recommended to create a separate user for Redis and create a new data and log folder

sudo useradd redis 
sudo mkdir -p /var/lib/redis 
sudo mkdir -p /var/log/redis 
sudo chown redis.redis /var/lib/redis  # db The file is here to be modified redis.conf 
sudo chown redis.redis /var/log/redis 

Configure the init script

Actually, there are a lot of startup scripts written by foreigners on github, but most of them are written by ubuntu, for Centos.

It has been modified as follows:

########################### 
PATH=/usr/local/bin:/sbin:/usr/bin:/bin 
   
REDISPORT=6379 
EXEC=/usr/local/bin/redis-server 
REDIS_CLI=/usr/local/bin/redis-cli 
   
PIDFILE=/var/run/redis.pid 
CONF="/etc/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 
############################## 

Save the above code as redis and put it under /etc/ init.d /

chmod +x /etc/init.d/redis 

If you want it to run as redis-server in the background, then

redis.conf needs to be modified to change daemonize no to daemonize yes

4. Set the startup service

sudo chkconfig redis on 

5. Start and stop redis

service redis start  # or  /etc/init.d/redis start 
service redis stop  # or  /etc/init.d/redis stop 

6. Test redis

redis-cli  
redis 127.0.0.1:6379> set foo 123 
OK 
redis 127.0.0.1:6379> get foo 
"123" 
redis 127.0.0.1:6379> exit
