Centos7 使用Docker安装rocket.chat聊天工具

下载安装

Rocket.Chat 目前最新的版本为 4.0.1，可以通过手动或者容器的方式安装。这里我推荐使用容器，部署过程会方便不少。

如果要用容器的方式部署，需要先安装 docker 和 docker-compose，再下载编排文件：

安装docker脚本

#!/bin/sh
#
#
setenforce 0

sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

systemctl stop firewalld && systemctl disable firewalld

swapoff -a && echo "swapoff -a" >> /etc/rc.local && chmod +x /etc/rc.local

yum install -y wget vim lrzsz telnet net-tools
yum install -y yum-utils device-mapper-persistent-data lvm2
yum install -y https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/docker-ce-18.06.3.ce-3.el7.x86_64.rpm
mkdir -p /etc/docker

cat > /etc/docker/daemon.json <<EOF
{
  "registry-mirrors": ["https://q2uvt0x7.mirror.aliyuncs.com"],
  "exec-opts": ["native.cgroupdriver=cgroupfs"],
  "data-root": "/data/docker",
  "storage-driver": "overlay2", 
  "storage-opts":["overlay2.override_kernel_check=true"],
  "log-driver": "json-file", 
  "log-opts": { 
      "max-size": "100m", 
      "max-file": "10" 
  }
}
EOF

systemctl enable docker && systemctl daemon-reload && systemctl start docker
echo "* soft nofile 655360" >> /etc/security/limits.conf
echo "* hard nofile 655360" >> /etc/security/limits.conf
echo "* soft nproc 655360"  >> /etc/security/limits.conf
echo "* hard nproc 655360"  >> /etc/security/limits.conf
echo "* soft  memlock  unlimited"  >> /etc/security/limits.conf
echo "* hard memlock  unlimited"  >> /etc/security/limits.conf
echo "DefaultLimitNOFILE=1024000"  >> /etc/systemd/system.conf
echo "DefaultLimitNPROC=1024000"  >> /etc/systemd/system.conf

ulimit -Hn
yum -y install chrony
systemctl enable chronyd.service && systemctl start chronyd.service && systemctl status chronyd.service
chronyc sources

安装docker-compose

yum install epel-release -y
yum install docker-compose -y

# 创建并进入工作目录
mkdir /opt/rocketchat
cd /opt/rocketchat
# 下载编排文件
curl -L https://raw.githubusercontent.com/RocketChat/Rocket.Chat/develop/docker-compose.yml -o docker-compose.yml

若下载失败，可使用下面文件

version: '2'

  #    - 443:443
  #  volumes:

根据自己的需求来修改编排文件，修改完成后，运行以下命令启动服务：

docker-compose up -d 

服务启动后，在浏览器中输入 http://{ip}:3000进行访问。

使用说明

第一次使用 Rocket.Chat 时，一些可能会不太习惯。不过不用担心，Rocket.Chat 用起来还是比较简单的。接下来，我会向大家演示 Rocket.Chat 的基本用法。

安装向导

我们第一次访问 Rocket.Chat 时，会被引导到安装向导，根据页面的提示来配置就好。
