Docker
1 基础知识
由于笔者需要将生产环境的Tigase迁移到Docker环境，所有产生本章节。
2 最佳实践
2.1 部署前的准备
2.1.1 部署Docker环境
本章使用如下Docker环境部署，参阅本章建议你先搭建以下Docker集群环境并熟悉，
2.1.2 准备Tigase镜像
In docker01
如果你需要参阅本章节，请参阅以下章节完成打包Tigase的私有镜像，
2.1.3 准备MySQL镜像
In docker01
cd /data/docker/images/ docker load -i mysql_5.6.34.tar docker tag mysql:5.6.34 docker01.cmdschool.org:5000/mysql:5.6.34 docker push docker01.cmdschool.org:5000/mysql:5.6.34 docker image rm mysql:5.6.34
另外，安装包的离线下载请在能上网的docker环境的机器上使用如下命令，
docker pull mysql:5.6.34 docker save mysql:5.6.34 -o mysql_5.6.34.tar
另外，其他版本请从以下链接下载，
https://hub.docker.com/_/mysql
2.2 部署Tigase
In docker01
2.2.1 创建服务配置文件
vim /data/docker/yml/tigase-stack.yml
加入如下配置，
version: '3.1'
services:
db:
image: docker01.cmdschool.org:5000/mysql:5.6.34
volumes:
- /data/docker/service/mysql/data:/var/lib/mysql
- /data/docker/service/mysql/conf:/etc/mysql
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_ROOT_PASSWORD: mysqlpwd
TZ: Asia/Shanghai
deploy:
replicas: 1
placement:
constraints: [node.labels.mysql == true]
logging:
driver: "json-file"
options:
max-size: "100m"
max-file: "5"
tigase:
image: docker01.cmdschool.org:5000/tigase-server:7.0.1
restart: always
environment:
TZ: Asia/Shanghai
ports:
- 8080:8080
- 5222:5222
deploy:
replicas: 1
placement:
constraints: [node.labels.tigase == true]
logging:
driver: "json-file"
options:
max-size: "100m"
max-file: "5"
根据配置需求创建数据存放目录，
In docker02
mkdir -p /data/docker/service/mysql/data mkdir -p /data/docker/service/mysql/conf/conf.d/
根据配置需求创建MySQL主配置文件，
vim /data/docker/service/mysql/conf/my.cnf
加入如下配置，
[mysqld] skip-host-cache skip-name-resolve # Copyright (c) 2015, Oracle and/or its affiliates. All rights reserved. # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; version 2 of the License. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

根据MySQL的主配置文件创建子目录配置，
vim /data/docker/service/mysql/conf/conf.d/docker.cnf
加入如下配置，
[mysqld] skip-host-cache skip-name-resolve
根据配置的需求设置运行标记，
In docker01
docker node update --label-add mysql=true docker02.cmdschool.org docker node update --label-add tigase=true docker01.cmdschool.org
2.2.2 部署服务
docker stack deploy -c /data/docker/yml/tigase-stack.yml tigase
2.3 使用Web向导配置tigase
2.3.1 生成配置文件
http://10.168.0.210:8080/setup/
按照以上向导提示生成配置（按照向导跑，简单这里不详述）并单击保存，对应的参数可按如下输入，
company name: cmdschool Your XMPP (Jabber) domains: cmdschool.org Server administrators: admin@cmdschool.org Admin password: ****** Select database: MySQL MySQL Super user account name: root MySQL Super user account password: mysqlpwd MySQL Database account: tigase MySQL Database Account password: tigasepwd MySQL Database name: tigasedb MySQL Database host or IP: 10.0.4.188 MySQL Additional database parameters: 留空
另外，需要注意的是，数据库主机需要用IP，IP查询的方法如下，
docker exec -it `docker container ls | grep 'tigase' | cut -d" " -f1 ` bash
然后通过Ping获取MySQL DB的地址，
ping db
可见如下显示，
PING db (10.0.4.188) 56(84) bytes of data. 64 bytes from 10.0.4.188 (10.0.4.188): icmp_seq=1 ttl=64 time=0.056 ms 64 bytes from 10.0.4.188 (10.0.4.188): icmp_seq=2 ttl=64 time=0.049 ms 64 bytes from 10.0.4.188 (10.0.4.188): icmp_seq=3 ttl=64 time=0.042 ms 64 bytes from 10.0.4.188 (10.0.4.188): icmp_seq=4 ttl=64 time=0.049 ms [...]
2.3.2 校验保存的配置
In docker01
docker exec -it `docker container ls | grep 'tigase' | cut -d" " -f1 ` bash
然后使用如下命令查看配置，
cat /etc/tigase/init.properties
可见如下配置，
config-type=--gen-config-def --virt-hosts=cmdschool.org --admins=admin@cmdschool.org --debug=server --user-db-uri=jdbc:mysql://localhost/tigasedb?user=tigase&password=tigasepwd --sm-plugins=+jabber\:iq\:auth,+urn\:ietf\:params\:xml\:ns\:xmpp-sasl,+urn\:ietf\:params\:xml\:ns\:xmpp-bind,+urn\:ietf\:params\:xml\:ns\:xmpp-session,+jabber\:iq\:register,+jabber\:iq\:roster,+presence,+basic-filter,+domain-filter,+jabber\:iq\:privacy,+jabber\:iq\:version,+http\://jabber.org/protocol/stats,+starttls,-msgoffline,+vcard-temp,+http\://jabber.org/protocol/commands,+jabber\:iq\:private,+urn\:xmpp\:ping,+pep,+zlib,+message-archive-xep-0136,+amp --comp-name-1=muc --comp-class-1=tigase.muc.MUCComponnet --comp-name-2=pubsub --comp-class-2=tigase.pubsub.PubSubComponent --comp-name-3=http --comp-class-3=tigase.http.HttpMessageReceiver
2.4 客户端测试
以上仅仅完成服务端的配置，如果需要进行客户端测试，请按照如下链接配置客户端，
