MongoDB Documentation, Release 3.0.4 Run MongoDB For example, from a system shell, you can extract through the tar command: tar -zxvf mongodb-osx-x86_64-3.0.4.tgz Copy the extracted folder to the location from which MongoDB will run. mkdir -p mongodb cp -R -n mongodb-osx-x86_64-3.0.4/ mongodb The MongoDB binaries are in the bin/ directory of the archive. To ensure that the binaries are in your PATH , you can modify your PATH . For example, you can add the following line to your shell’s rc file (e.g. ~/.bashrc ): export PATH=<mongodb-install-directory>/bin:$PATH Replace <mongodb-install-directory> with the path to the extracted MongoDB archive. Before you start MongoDB for the first time, create the directory to which the mongod process will write data. By default, the mongod process uses the /data/db directory. If you create a directory other than this one, you must specify that directory in the dbpath option when starting the mongod process later in this procedure. The following example command creates the default /data/db directory: mkdir -p /data/db Before running mongod for the first time, ensure that the user account running mongod has read and write permis- sions for the directory. To run MongoDB, run the mongod process at the system prompt. If necessary, specify the path of the mongod or the data directory. See the following examples. Run without specifying paths If your system PATH variable includes the location of the mongod binary and if you use the default data directory (i.e., /data/db ), simply enter mongod at the system prompt: Step 3: Run MongoDB. Step 2: Set permissions for the data directory. Step 4: Ensure the location of the binaries is in the PATH variable. Step 3: Copy the extracted archive to the target directory. Step 1: Create the data directory. Step 2: Extract the files from the downloaded archive. 26 Chapter 2. Install MongoDB
