一、前言
阅读这篇文章之前，建议你先阅读一下 阿里混沌工程-chaosblade工具初识
[root@rabbit-node1 ~]# blade create -h
Create a chaos engineering experiment
Usage:
blade create [command]
Aliases:
create, c
Examples:
blade create cpu load --cpu-percent 60
Available Commands:
cplus C++ chaos experiments
cpu Cpu experiment
disk Disk experiment
docker Docker experiment
druid Experiment with the Druid
dubbo Experiment with the Dubbo
es ElasticSearch experiment!
file File experiment
gateway gateway experiment!
hbase hbase experiment!
http http experiment
jedis jedis experiment
jvm Experiment with the JVM

network Network experiment
process Process experiment

rocketmq Rocketmq experiment,can make message send or pull delay and exception
script Script chaos experiment
servlet java servlet experiment
strace strace experiment
systemd Systemd experiment
tars tars experiment
Flags:
-a, --async whether to create asynchronously, default is false
-e, --endpoint string the create result reporting address. It takes effect only when the async value is true and the value is not empty
-h, --help help for create
-n, --nohup used to internal async create, no need to config
--uid string Set Uid for the experiment, adapt to docker
Global Flags:
-d, --debug Set client to DEBUG mode
Use "blade create [command] --help" for more information about a command.
二、mysql试验
mysql的混沌测试是基于
jdbc实现的，因此运行blade create mysql delay试验之前，通常先进行java agent attach操作即使用blade prepare jvm --pid 16865进行agent挂载(该步骤也可省略，隐式挂载);
常用试验场景delay和throwCustomException
[root@rabbit-node1 ~]# blade create mysql -h
Mysql experiment contains delay and exception by table name and so on.
Usage:
blade create mysql [flags]
blade create mysql [command]
Available Commands:
delay delay time
throwCustomException throw custom exception
Flags:
-h, --help help for mysql
Global Flags:
-a, --async whether to create asynchronously, default is false
-d, --debug Set client to DEBUG mode
-e, --endpoint string the create result reporting address. It takes effect only when the async value is true and the value is not empty
-n, --nohup used to internal async create, no need to config
--uid string Set Uid for the experiment, adapt to docker
Use "blade create mysql [command] --help" for more information about a command.
1.delay试验
[root@rabbit-node1 ~]# blade create mysql delay -h
Mysql delay experiment
Usage:
blade create mysql delay
Examples:
# Do a delay 2s experiment for mysql client connection port=3306 INSERT statement
blade create mysql delay --time 2000 --sqltype select --port 3306
Flags:
--database string The database name which used
--effect-count string The count of chaos experiment in effect
--effect-percent string The percent of chaos experiment in effect
-h, --help help for delay
--host string The database host
--javaHome string Specify the JAVA_HOME variable to loading jre lib
--offset string delay offset for the time
--pid string The process id
--port string The database port which used
--process string Application process name
--refresh Uninstall java agent and reload it
--sqltype string The sql type, for example, select, update and so on.
--table string The first table name in sql.
--time string delay time (required)
--timeout string set timeout for experiment in seconds
Global Flags:
-a, --async whether to create asynchronously, default is false
-d, --debug Set client to DEBUG mode
-e, --endpoint string the create result reporting address. It takes effect only when the async value is true and the value is not empty
-n, --nohup used to internal async create, no need to config
--uid string Set Uid for the experiment, adapt to docker
先通过
jps -l命令，查看需要挂载的java应用的进程号（本例中为16865）
- java应用 (部分代码截取)
spring:
datasource:
url: jdbc:mysql://192.168.198.1:3306/db1?serverTimezone=GMT%2B8&characterEncoding=utf8&useUnicode=true
username: root
password: 123456
server:
port: 8888
@GetMapping("/mysql")
public List<Map<String, Object>> mysql() {
final List<Map<String, Object>> list = jdbcTemplate.queryForList("select * from test limit 5");
return list;
}
[root@rabbit-node1 ~]# jps -l
16865 blade-0.0.1-SNAPSHOT.jar
52074 sun.tools.jps.Jps
- delay试验
官方示例:
blade create mysql delay --time 2000 --sqltype select --port 3306(注意：执行该语句前，一定要先进行java agent挂载操作)，如果你想增加更多限制如host、port、database,可使用如下命令:
blade create mysql delay --database db1 --host 192.168.198.1 --port 3306 --pid 16865 --sqltype select --table test --time 4000
- 延迟测试
time curl http://localhost:8888/mysql
- 销毁试验
blade destroy "e0b2cafeadd5ad31"
blade status --type prepare
blade revoke "9817c390d0f98b57"
2.throwCustomException试验
[root@rabbit-node1 ~]# blade create mysql throwCustomException -h
Mysql throws customer exception experiment
Usage:
blade create mysql throwCustomException
Aliases:
throwCustomException, tce
Examples:
# Do a throws customer exception experiment for mysql client connection port=3306 INSERT statement
blade create mysql throwCustomException --exception java.lang.Exception
Flags:
--database string The database name which used
--effect-count string The count of chaos experiment in effect
--effect-percent string The percent of chaos experiment in effect
--exception string Exception class inherit java.lang.Exception (required)
--exception-message string Specify exception message for exception experiment, default value is chaosblade-mock-exception
-h, --help help for throwCustomException
--host string The database host
--javaHome string Specify the JAVA_HOME variable to loading jre lib
--pid string The process id
--port string The database port which used
--process string Application process name
--refresh Uninstall java agent and reload it
--sqltype string The sql type, for example, select, update and so on.
--table string The first table name in sql.
--timeout string set timeout for experiment in seconds
Global Flags:
-a, --async whether to create asynchronously, default is false
-d, --debug Set client to DEBUG mode
-e, --endpoint string the create result reporting address. It takes effect only when the async value is true and the value is not empty
-n, --nohup used to internal async create, no need to config
--uid string Set Uid for the experiment, adapt to docker
- throwCustomException试验
blade prepare jvm --pid 16865
blade create mysql throwCustomException --exception java.lang.Exception
- 异常测试
time curl http://localhost:8888/mysql
- 销毁试验
blade destroy "191262659a5b664e"
blade status --type prepare
blade revoke "66870aef759696ec"
三、mongodb、es、rabbitmq、rocketmq试验等
用法同
mysql，不同的target支持的参数有细微区别，例如：
blade create es throwCustomException --exception java.lang.Exception --index index2
blade create rocketmq throwCustomException --exception java.lang.Exception --topic=xx --consumerGroup=xx
blade create mongodb -h
blade create es -h
blade create rabbitmq -h
blade create rocketmq-h
四、gateway试验
blade create gateway -h
1.gateway试验
[root@rabbit-node1 ~]# blade create gateway delay -h
SpringCloud Gateway delay experiment
Usage:
blade create gateway delay
Examples:
# Do a delay 2s experiment for SpringCloud Gateway forward operations
blade create gateway delay --requestPath /gateway/path --time 2000

--effect-count string The count of chaos experiment in effect
--effect-percent string The percent of chaos experiment in effect
-h, --help help for delay
--javaHome string Specify the JAVA_HOME variable to loading jre lib
--offset string delay offset for the time
--pid string The process id
--process string Application process name
--refresh Uninstall java agent and reload it
--requestPath string The gateway path which used (required)
--time string delay time (required)
--timeout string set timeout for experiment in seconds
Global Flags:
-a, --async whether to create asynchronously, default is false
-d, --debug Set client to DEBUG mode
-e, --endpoint string the create result reporting address. It takes effect only when the async value is true and the value is not empty
-n, --nohup used to internal async create, no need to config
--uid string Set Uid for the experiment, adapt to docker
- delay试验
blade prepare jvm --pid 16865
blade create gateway delay --requestPath /gateway/path --time 2000
