yum安装MongoDB
- 添加MongoDB源
# vi /etc/yum.repos.d/mongodb-org-3.0.repo[mongodb-org-3.0] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/7/mongodb-org/3.0/x86_64/ gpgcheck=0 enabled=1
- MongoDB包
mongodb-org This package is a metapackage that will automatically install the four component packages listed below. mongodb-org-server This package contains the mongod daemon and associated configuration and init scripts. mongodb-org-mongos This package contains the mongos daemon. mongodb-org-shell This package contains the mongo shell. mongodb-org-tools This package contains the following MongoDB tools: mongoimport bsondump, mongodump, mongoexport, mongofiles, mongooplog, mongoperf, mongorestore, mongostat, and mongotop.
- 安装MongoDB
# yum install -y mongodb-org - 设置MongoDB服务开机自启动
# chkconfig mongod on - 启动MongoDB服务
# service mongod start
备注:卸载MongoDB
- 停止MongoDB服务
# service mongod stop - 卸载MongoDB安装包
# yum erase $(rpm -qa | grep mongodb-org) - 删除数据库和日志目录
# rm -r /var/lib/mongo
# rm -r /var/log/mongodb
手动安装MongoDB
- 下载MongoDB安装包
# curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.0.7.tgz - 解压缩MongoDB
# tar -zxvf mongodb-linux-x86_64-3.0.7.tgz - 移动到安装目录
# mv mongodb-linux-x86_64-3.0.7 /usr/local/mongodb - 设置环境变量
# echo “export PATH=\$PATH:/usr/local/mongodb/bin” > /etc/profile.d/mongodb.sh
# source /etc/profile.d/mongodb.sh - 创建mongod用户和用户组
# useradd -r -M -s /sbin/nologin mongod - 创建数据库和日志目录并修改属组
# mkdir -p /data/mongodb/{db,log}/
# chown -R mongod:mongod /data/mongodb/ - 创建MongoDB配置文件
# vi /etc/mongod.conf# mongod.conf # for documentation of all options, see: # http://docs.mongodb.org/manual/reference/configuration-options/ # where to write logging data. systemLog: destination: file logAppend: true path: /data/mongodb/log/mongod.log # Where and how to store data. storage: dbPath: /data/mongodb/db journal: enabled: true # engine: # mmapv1: # wiredTiger: # how the process runs processManagement: fork: true # fork and run in background pidFilePath: /var/run/mongodb/mongod.pid # location of pidfile # network interfaces net: port: 27017 bindIp: 127.0.0.1 # Listen to local interface only, comment to listen on all interfaces. #security: #operationProfiling: #replication: #sharding: ## Enterprise-Only Options #auditLog: #snmp:
备注:
如果MongoDB端口不在27017-27019, 28017-28019之间,需要执行以下步骤:
# yum -y install policycoreutils-python
# semanage port -a -t mongod_port_t -p tcp <port_number>
- 创建MongoDB自启动脚本

- 设置MongoDB服务开机自启动
# chmod +x /etc/init.d/mongod
# chkconfig mongod on - 启动MongoDB服务
# service mongod start
备注:
如果启动发生错误,请检查数据库和日志目录及里面文件的权限是否设置正确,再次运行前须删除数据库目录下的mongod.lock文件。
