准备

1.CentOs 7.6 x86_64
2.Mongodb 4.0.9
3.NodeJs
4.Rocket.Chat最新版
5.服务器开放3000端口

首先执行下方代码

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

sudo yum install -y curl && sudo curl -sL https://rpm.nodesource.com/setup_12.x | sudo bash -

sudo yum install -y gcc-c++ make mongodb-org nodejs

sudo yum install -y epel-release && sudo yum install -y GraphicsMagick

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

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

查看一下README文件中需要的NODEJS的版本

cat /tmp/bundle/README

然后下载

sudo npm install -g inherits n && sudo n 8.17.0（换成README里的版本号）

继续安装Rocket.chat

cd /tmp/bundle/programs/server && sudo npm install
sudo mv /tmp/bundle /opt/Rocket.Chat
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

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

查看是否正常启动

sudo systemctl status rocketchat

正常启动为下图

由于我下载的Rocket.chat版本需要的NodeJs需要的版本是12.22.1
所以，完整代码为

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

gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc

EOF

sudo yum install -y gcc-c++ make mongodb-org nodejs

sudo yum install -y epel-release && sudo yum install -y GraphicsMagick

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

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

sudo npm install -g inherits n && sudo n 12.22.1

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

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

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

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

复制保存为install.sh，然后执行。

部署完访问VPS的IP:3000就进入web安装页面，填写管理员等信息就可以正常使用了。
