　　2、这里贴一下步骤

Rocket.Chat in CentOS
This installation guide was tested in the following environment:

Rocket.Chat 1.0.2
OS: CentOS 7.6
Mongodb 4.0.9
NodeJS 8.11.4

Install necessary dependency packages
#---安装依赖包
Update package list and configure yum to install the official MongoDB packages with the following yum repository file:
#---配置repo源
sudo yum -y check-update
cat << EOF | sudo tee -a /etc/yum.repos.d/mongodb-org-4.0.repo
[mongodb-org-4.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc
EOF
Configure Node.js to be installed via package manager:
#---配置node.js
sudo yum install -y curl && curl -sL https://rpm.nodesource.com/setup_8.x | sudo bash -
Install build tools, MongoDB, nodejs and graphicsmagick:
#---安装mongondb,nodejs,graphicsmagick
sudo yum install -y gcc-c++ make mongodb-org nodejs
sudo yum install -y epel-release && sudo yum install -y GraphicsMagick
Using npm install inherits and n, and the node version required by Rocket.Chat:
#---使用NPM安装 inherits，n，以及指定版本
sudo npm install -g inherits n && sudo n 8.11.4
Install Rocket.Chat
Download the latest Rocket.Chat version:
#---安装rocket.chat
curl -L https://releases.rocket.chat/latest/download -o /tmp/rocket.chat.tgz
tar -xzf /tmp/rocket.chat.tgz -C /tmp
Install (this guide uses /opt but feel free to choose a different directory):
#---这里使用得opt目录，也可以是其他目录
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:
#---配置rocket.chat服务，包括：添加rocketchat 用户，设置文佳佳权限创建服务文件
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
[Unit]
Description=The Rocket.Chat server
After=network.target remote-fs.target nss-lookup.target nginx.target mongod.target
[Service]
ExecStart=/usr/local/bin/node /opt/Rocket.Chat/main.js
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocketchat
User=rocketchat
Environment=MONGO_URL=mongodb://localhost:27017/rocketchat?replicaSet=rs01 MONGO_OPLOG_URL=mongodb://localhost:27017/local?replicaSet=rs01 ROOT_URL=http://localhost:3000/ PORT=3000
[Install]
WantedBy=multi-user.target
EOF
Open the Rocket.Chat service file just created (/usr/lib/systemd/system/rocketchat.service) using sudo and your favourite text editor, and change the ROOT_URL environmental variable to reflect the URL you want to use for accessing the server (optionally change MONGO_URL, MONGO_OPLOG_URL and PORT):
#---打开服务文件，编辑改变ROOT_URL、MONGO_URL、MONGO_OPLOG_URL、PORT
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:
#---mongoDB设置存储引擎和replication，开机自启，启动数据库
sudo sed -i "s/^#  engine:/  engine: mmapv1/"  /etc/mongod.conf
sudo sed -i "s/^#replication:/replication:\n  replSetName: rs01/" /etc/mongod.conf
sudo systemctl enable mongod && sudo systemctl start mongod
mongo --eval "printjson(rs.initiate())"
sudo systemctl enable rocketchat && sudo systemctl start rocketchat
Optional configurations
#---可选配置
Configure firewall rule Configure a HTTP reverse proxy to access Rocket.Chat server [Configure mongo access control] [Configure production values for mongodb]

Configure your Rocket.Chat server
Open a web browser and access the configured ROOT_URL (http://your-host-name.com-as-accessed-from-internet:3000), follow the configuration steps to set an admin account and your organization and server info.

ZLIB version problem
Some users had experienced problems starting rocketchat server in CentOS because their zlib version is not compatible with rocket.chat.

If you find an error message similar to the following in the logs:

Exception in callback of async function: Error: /lib64/libz.so.1: version `ZLIB_1.2.9' not found
Add this environmental variable in the Rocket.Chat service file (/usr/lib/systemd/system/rocketchat.service):

Environment=LD_PRELOAD=/opt/Rocket.Chat/programs/server/npm/node_modules/sharp/vendor/lib/libz.so
