CentOS7 安装 MongoDB

方法 1：RPM 包安装

访问官网页面下载 rpm 包

https://www.mongodb.com/download-center/community

# mongodb服务端
wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/3.6/x86_64/RPMS/mongodb-org-server-3.6.14-1.el7.x86_64.rpm
# mongodb 客户端连接工具 mongo
wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/3.6/x86_64/RPMS/mongodb-org-shell-3.6.14-1.el7.x86_64.rpm
# mongodb 工具集合：mongoimport, bsondump, mongodump, mongoexport, mongofiles, mongorestore, mongostat, mongotop
wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/3.6/x86_64/RPMS/mongodb-org-tools-3.6.14-1.el7.x86_64.rpm

安装 mongodb server

yum install mongodb-org-server-3.6.14-1.el7.x86_64.rpm mongodb-org-tools-3.6.14-1.el7.x86_64.rpm mongodb-org-tools-3.6.14-1.el7.x86_64.rpm

设置远程访问
修改/etc/mongod.conf文件bindIP部分
```
net:
  port: 27017
  bindIp: 0.0.0.0
```

启动服务并开机自启

systemctl restart mongod.service
systemctl status mongod.service
systemctl enable mongod.service

方法 2：两进制文件安装

下载二进制文件

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-3.6.14.tgz

安装依赖
```
yum install libcurl openssl
```

创建 mongo 用户和组

/usr/sbin/groupadd -r mongod
/usr/sbin/useradd -M -r -g mongod -d /var/lib/mongo -s /bin/false -c mongod mongod

解压文件

tar xvf mongodb-linux-x86_64-rhel70-3.6.14.tgz
mv mongodb-linux-x86_64-rhel70-3.6.14 /opt/mongodb

配置环境变量

echo '
# MongoDB
export PATH=$PATH:/opt/mongodb/bin
' >> /etc/profile
source /etc/profile

创建配置文件

创建/etc/mongod.conf文件,内容如下

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

# Where and how to store data.
storage:
  dbPath: /var/lib/mongo
  journal:
    enabled: true

# how the process runs
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile
  timeZoneInfo: /usr/share/zoneinfo

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0

# log
mkdir -p /var/log/mongodb/
chown -R mongod:mongod /var/log/mongodb/
# dbPath
mkdir -p /var/lib/mongo
chown -R mongod:mongod /var/lib/mongo

注册系统服务

创建/lib/systemd/system/mongod.service文件，内容如下

[Unit]
Description=MongoDB Database Server
Documentation=https://docs.mongodb.org/manual
After=network.target

[Service]
User=mongod
Group=mongod
Environment="OPTIONS=-f /etc/mongod.conf"

ExecStartPre=/usr/bin/mkdir -p /var/run/mongodb
ExecStartPre=/usr/bin/chown mongod:mongod /var/run/mongodb
ExecStartPre=/usr/bin/chmod 0755 /var/run/mongodb
PermissionsStartOnly=true
PIDFile=/var/run/mongodb/mongod.pid
Type=forking
# file size
LimitFSIZE=infinity
# cpu time
LimitCPU=infinity
# virtual memory size
LimitAS=infinity
# open files
LimitNOFILE=64000
# processes/threads
LimitNPROC=64000
# locked memory
LimitMEMLOCK=infinity
# total threads (user+kernel)
TasksMax=infinity
TasksAccounting=false
# Recommended limits for for mongod as specified in
# http://docs.mongodb.org/manual/reference/ulimit/#recommended-settings

[Install]
WantedBy=multi-user.target

重新加载 systemd
```
systemctl daemon-reload
```

启动服务并设置开机自启

systemctl restart mongod.service
systemctl status mongod.service
systemctl enable mongod.service
