mongodb 安装及开机自动启动

       Linux下Mongodb数据库安装及开机自启

1）注意事项：

A. 在这里使用的是SecureCRT进行操作。

B. 下面以#开头的都是对下面一行操作的解释

2）前提准备：

A. 到mongodb官网下载对应的安装包。这里我选择的是mongodb cummunity server下面linux版本中的rhel（Red Hat Enterprise Linux的缩写）最新版本。

 

当前时间2018-1-28号最新版本：https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-3.6.2.tgz下载我们的mongodb-linux-x86_64-rhel70-3.6.2.tgz文件。

B. 建立mongodb.conf文件，其中内容如下

bind_ip = 0.0.0.0

port = 47017

dbpath = /usr/local/mongodb3.6.2/bin/data/db

logpath = /usr/local/mongodb3.6.2/bin/data/logs/mongodb.log

logappend = true

fork = true

C. 建立mongod.service文件，其中内容如下

[Unit]

 

Description=mongodb

After=network.target remote-fs.target nss-lookup.target

 

[Service]

Type=forking

ExecStart=/usr/local/mongodb3.6.2/bin/mongod --config /usr/local/mongodb3.6.2/bin/mongodb.conf

ExecReload=/bin/kill -s HUP $MAINPID

ExecStop=/usr/local/mongodb3.6.2/bin/mongod --shutdown --config /usr/local/mongodb3.6.2/bin/mongodb.conf

PrivateTmp=true

 

[Install]

WantedBy=multi-user.target

3）具体操作。

我们会发现47017端口是打开的，我们的mongodb自启动是成功的
