使用centos7安装rocket.chat

安装说明

首先访问rocket.chat的官网 点这里
官网很详细的说明了不同操作系统的安装方式如Ubuntu 、centos
这是只说centos7的安装步骤，其余的请在官网自行浏览
1.进入官网点击install选择centos如下图所示

点击centos进入官方的安装界面如图所示：

可以看到官方使用的是Centos 7.6 ，其中还包括Mongodb 4.0.9和NodeJS 12.14.0。

安装步骤

1.Install necessary dependency packages–安装必须依赖的包

Update package list and configure yum to install the official MongoDB packages with the following yum repository file – 更新你的yum包 并且安装MongoDB

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 --通过yum的包管理器来安装Node.js

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

Install build tools, MongoDB, nodejs and graphicsmagick–使用构建工具安装MongoDB、nodejs和 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来安装依赖和切换到Rocket.Chat要求的node的版本

sudo npm install -g inherits n && sudo n 12.14.0

2.Install Rocket.Chat–安装Rocket.Chat
Download the latest Rocket.Chat version–下载最新的Rocket.Chat的版本

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)–安装（可以选择不同的目录）

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

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

3.Configure the Rocket.Chat service–Rocket.Chat的配置
Add the rocketchat user, set the right permissions on the Rocket.Chat folder and create the Rocket.Chat service file–添加用户并创建正确的权限来创建Rocket的服务

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

使用 vi修改刚刚写的rocketchat.service 将ROOT_URL配置成你自己ip的url。
4.Setup storage engine and replication for MongoDB (mandatory for versions > 1), and enable and start MongoDB and Rocket.Chat–设置MongoDB的存储和版本，并且启动MongoDB和Rocket

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())"

后台运行和启动rocket

sudo systemctl enable rocketchat && sudo systemctl start rocketchat

查看当前rocket启动否成功

sudo systemctl status rocketchat

关闭rocket

sudo systemctl stop rocketchat

此时rocket配置完成，使用自己的ip:3000访问此地址进入rocket的配置页面完成配置登录进入聊天界面，此时rocket配置完成

使用nginx反向代理配置

如有没有是https访问的rocket使用视频是无法显示的，因为rocket是使用webrct来做的web端，由于webrtc必须要使用https所以我们还要配置https
1.安装nginx
首先安装编译工具和库文件

yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

 cd /usr

wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

tar zxvf pcre-8.35.tar.gz

cd pcre-8.35

./configure -prefix-/usr/pce

make && make install

 cd /usr

wget http://nginx.org/download/nginx-1.6.2.tar.gz

tar zxvf nginx-1.6.2.tar.gz

 cd nginx-1.6.2

/configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/pcre-8.35

make&&makeinstall

查看nginx的版本

usr/local/nginx/sbin/nginx -v

nginx安装完成。

nginx配置

/usr/sbin/groupadd www 

/usr/sbin/groupadd www 

cat /usr/local/nginx/conf/nginx.conf

    location ~ .*\.(js|css)?$
    {
      expires 15d;
   # access_log off;
    }
    access_log off;
  }

}

验证配置的正确行

/usr/local/nginx/sbin/nginx -t

启动nginx

/usr/local/nginx/sbin/nginx

使用ip访问出现如下截图说明配置成功

nginx反向代理配置Rocket

在官方中说明如下图所示

在官方中说明当配置https的时候需要把ROOT_URL中的3000端口去掉，改成你自己的域名如下图所示：

打开nginx的配置文件

vi /usr/local/nginx/conf/nginx.conf

将server替换

# Upstreams
upstream backend {
    server 127.0.0.1:3000;
}

# HTTPS Server

server {
    listen 443;
    server_name your_hostname.com;

    # You can increase the limit if your need to.
    client_max_body_size 200M;

    error_log /var/log/nginx/rocketchat.access.log;#创建记录错误的日志 可以访问早nginx的目录就可以了 rocketchat.access.log会自动生成

    ssl on;
    ssl_certificate /etc/nginx/certificate.crt;#你自己的证书crt
    ssl_certificate_key /etc/nginx/certificate.key;#你自己的证书key
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # don’t use SSLv3 ref: POODLE

    location / {
        proxy_pass http://0.0.0.0:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forward-Proto http;
        proxy_set_header X-Nginx-Proxy true;
        proxy_redirect off;
    }
}

配置完成后验证nginx配置文件的正确性
重新加载nginx

/usr/local/nginx/sbin/nginx -s reload 

使用你自己的域名通过htpps来访问。
