Here is a quickstep to set Celery as daemon in Ubuntu 14.04 for production:
Create file “/etc/init.d/celeryd” :

Now make it executable :
1 | sudo chmod a+x /etc/init.d/celeryd |
Then create “/etc/default/celeryd” :
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | # App instance to use # comment out this line if you don’t use an app CELERY_APP="yourprojectname" # Where to chdir at start. CELERYD_CHDIR="/path/to/your/project" # Names of nodes to start # most will only start one node: CELERYD_NODES="worker1" # but you can also start multiple and configure settings # for each in CELERYD_OPTS (see `celery multi –help` for examples). CELERYD_NODES="worker" # Absolute or relative path to the ‘celery’ command: CELERY_BIN="/usr/local/bin/celery" #CELERY_BIN="/virtualenvs/def/bin/celery" # Extra command-line arguments to the worker CELERYD_OPTS="–time-limit=300 –concurrency=8" # %N will be replaced with the first part of the nodename. CELERYD_LOG_FILE="/var/log/celery/%N.log" CELERYD_PID_FILE="/var/run/celery/%N.pid" # Workers should run as an unprivileged user. # You need to create this user manually (or you can choose # a user/group combination that already exists, e.g. nobody). CELERYD_USER="ubuntu" CELERYD_GROUP="ubuntu" # If enabled pid and log directories will be created if missing, # and owned by the userid/group configured. CELERY_CREATE_DIRS=1 |
Then, we need to chown required folder :
1 2 | sudo chown ubuntu -R /var/run/celery/ sudo chown ubuntu -R /var/log/celery |
Now we ready to start the services by
1 | sudo service celeryd start |
You can see the log at “/var/log/celery/worker.log”
For Celerybeat, create file “/etc/init.d/celerybeat” :
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 | #!/bin/bash # ========================================================= # celerybeat – Starts the Celery periodic task scheduler. # ========================================================= # # :Usage: /etc/init.d/celerybeat {start|stop|force-reload|restart|try-restart|status} # :Configuration file: /etc/default/celerybeat or /etc/default/celeryd # # See http://docs.celeryproject.org/en/latest/tutorials/daemonizing.html#generic-init-scripts ### BEGIN INIT INFO # Provides: celerybeat # Required-Start: $network $local_fs $remote_fs # Required-Stop: $network $local_fs $remote_fs # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: celery periodic task scheduler ### END INIT INFO # Cannot use set -e/bash -e since the kill -0 command will abort # abnormally in the absence of a valid process ID. #set -e VERSION=10.1 echo "celery init v${VERSION}." if [ $(id -u) -ne 0 ]; then echo "Error: This program can only be used by the root user." echo " Unpriviliged users must use ‘celery beat –detach’" exit 1 fi # May be a runlevel symlink (e.g. S02celeryd) if [ -L "$0" ]; then SCRIPT_FILE=$(readlink "$0") else SCRIPT_FILE="$0" fi SCRIPT_NAME="$(basename "$SCRIPT_FILE")" # /etc/init.d/celerybeat: start and stop the celery periodic task scheduler daemon. # Make sure executable configuration script is owned by root _config_sanity() { local path="$1" local owner=$(ls -ld "$path" | awk ‘{print $3}’) local iwgrp=$(ls -ld "$path" | cut -b 6) local iwoth=$(ls -ld "$path" | cut -b 9) if [ "$(id -u $owner)" != "0" ]; then echo "Error: Config script ‘$path’ must be owned by root!" echo echo "Resolution:" echo "Review the file carefully and make sure it has not been " echo "modified with mailicious intent.

Then make it executable by “sudo chmod a+x /etc/init.d/celerybeat”.
Now, setup configuration by create file “/etc/default/celerybeat” :
1 2 3 4 5 6 7 8 | # Where to chdir at start. CELERYBEAT_CHDIR="/project/path/" # Extra arguments to celerybeat CELERYBEAT_OPTS="–schedule=/var/run/celery/celerybeat-schedule" # Name of the celery config module.# CELERY_CONFIG_MODULE="celeryconfig" |
And start celerybeat by :
1 | sudo service celerybeat start |
