==========安装start================

安装步骤：

Install necessary dependency packages

Update package list and configure apt to install the official MongoDB packages with the following repository file:

sudo apt-get -y update

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4

echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list

Configure Node.js to be installed via package manager:

sudo apt-get -y update && sudo apt-get install -y curl && curl -sL https://deb.nodesource.com/setup_12.x | sudo bash -

Install build tools, MongoDB, nodejs and graphicsmagick:

sudo apt-get install -y build-essential mongodb-org nodejs graphicsmagick

Using npm install inherits and n, and the node version required by Rocket.Chat:

sudo npm install -g inherits n && sudo n 12.18.4

Install Rocket.Chat

Download the latest Rocket.Chat version:

curl -L https://releases.rocket.chat/latest/download -o /tmp/rocket.chat.tgz

tar -xzf /tmp/rocket.chat.tgz -C /tmp

cd /tmp/bundle/programs/server && npm install

sudo mv /tmp/bundle /opt/Rocket.Chat

Configure the Rocket.Chat service

Add the rocketchat user, set the right permissions on the Rocket.Chat folder and create the Rocket.Chat service file:

sudo useradd -M rocketchat && sudo usermod -L rocketchat

sudo chown -R rocketchat:rocketchat /opt/Rocket.Chat

cat << EOF |sudo tee -a /lib/systemd/system/rocketchat.service

/lib/systemd/system/rocketchat.service修改成你自己的域名

MONGO_URL=mongodb://localhost:27017/rocketchat?replicaSet=rs01

MONGO_OPLOG_URL=mongodb://localhost:27017/local?replicaSet=rs01

ROOT_URL=http://your-host-name.com-as-accessed-from-internet:3000

PORT=3000

Setup storage engine and replication for MongoDB (mandatory for versions > 1), and enable and start MongoDB and Rocket.Chat:

sudo sed -i "s/^# engine:/ engine: mmapv1/" /etc/mongod.conf

MongoDB Versions >= 4.2.加下面一条配置

sudo sed -i "s/^#replication:/replication:\n replSetName: rs01/" /etc/mongod.conf

####我的配置###

sudo systemctl enable mongod && sudo systemctl start mongod

mongo --eval "printjson(rs.initiate())"

sudo systemctl enable rocketchat && sudo systemctl start rocketchat

启动日志：

 

登录rocketchat.service配置的URL登录或者http://ip:3000即可，第一次启动加载较慢，请耐心等待。

 

 

 

 

===================基本安装end===========

其他注意项目：

 MONGODB4.0版本低：

高版本安装：

停止服务：sudo service mongod stop

清除软件包和软件的配置文件：sudo apt-get purge mongodb-org*

清理相干文件：sudo rm -r /var/log/mongodb /var/lib/mongodb

从头再来的话find / -name mongo* |xargs rm -rf

获取apt 所用的记录软件包仓库位置的配置文件：

wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -

echo "deb http://repo.mongodb.org/apt/debian buster/mongodb-org/5.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list

wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | sudo apt-key add -

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list

检查包明细：apt-cache policy mongodb-org

更新和安装需要的版本mongodb：

sudo apt update

sudo apt-get install -y mongodb-org=4.2.17 mongodb-org-server=4.2.17 mongodb-org-shell=4.2.17 mongodb-org-mongos=44.2.17 mongodb-org-tools=4.2.17
