Wherein, gorlisten can be arranged on the nginx server for load balancing in production environment, gorreplay can be arranged on the nginx server for load balancing in test environment, also can be arranged on the independently server outside independent of production environment and test environment.
When in production environment in the nginx server of load balancing and test environment for the nginx server of load balancing or independently on server after operating flux Replication Tools, instruction (i.e. sudo./program/gor_x64/gor--input-raw:8180--output-tcp10. 204.76.237:28020-output-tcp-stats-output-http-stats-stat s--output-http-workers=-1) is sent by performing on the nginx server of load balancing in production environment, like this, just start to copy each service request for the nginx server of load balancing in production environment, and send to gorreplay.Wherein, 10.205.76.237 be the Internet protocol (IP for the nginx server of load balancing in production environment, InternetProtocol) address,: 8180 is the entrance for the nginx server of load balancing in production environment: 28020 is the port that flow Replication Tools inside uses.Its replicating principle catches HTTP (http, HypertextTransferProtocol) transmission control protocol (tcp of port, TransmissionControlProtocol) wrap, amendment destination address, and the nginx server be transmitted to for load balancing in test environment, service request is transmitted to testing server by the nginx server for load balancing in test environment.
When in test environment for the nginx server of load balancing or after independently server performing and receiving instruction (i.e. sudo ~/program/gor_x64/gor--input-tcp10.204.76.237:28020--outpu t-http " http: // 127.1:8180 "-output-tcp-stats-output-http-stats – stats), in test environment for the nginx server of load balancing or independently server start to receive each service request for the nginx server replicates of load balancing in production environment, and distribute to testing server and carry out load testing.Wherein, 10.205.76.237 is the IP address for the nginx server of load balancing or independently server in test environment,
http: // 127.1:8180for the entry address for the nginx server of load balancing or independently server in test environment.
When in test environment for the nginx server of load balancing or independently server does not perform receive instruction time, abandon receive from production environment for each service request of the nginx server of load balancing.
In this step, in production environment in the nginx server of load balancing and test environment for the nginx server of load balancing or after independently server starts to send and receives each service request of copying, user can adopt packet catcher to check in production environment for the access log for the nginx server of load balancing or independently server in the nginx server of load balancing and test environment, and carry out contrasting and check in production environment and whether each service request received correctly is copied in test environment for the nginx server of load balancing or independently server for the nginx server of load balancing.
Further, also comprise before the method:
Pre-set the quantity of testing server for the nginx server of load balancing in test environment; Or testing server pre-set self heap capacity and, the size of total thread stack and concurrent thread quantity.
Wherein, concurrent thread quantity comprises following one or more: the Thread Count created when maximum concurrent thread quantity, initialization, the Thread Count created when closing the thread no longer needed.
The method also comprises:
For the quantity of the nginx server update testing server of load balancing in test environment; Or the size of the heap capacity of testing server renewal self and/or always thread stack and/or concurrent thread quantity.
Such as, when in production environment for the nginx server of load balancing under comprise 3 application servers, application server is 4 core CPU, 16 gigabits (GB) internal memory, Java Virtual Machine (JVM on application server, JavaVirtualMachine) heap capacity is 1GB, when the size of total thread stack is 256KB, can arrange in test environment for comprising 2 testing servers under the nginx server of load balancing, testing server is 1 core CPU, 2GB internal memory, the heap capacity of the JVM on testing server is 512MB, the size of thread stack is 256KB, after using this configuration monitoring a period of time, the configuration that can change test environment proceeds monitoring.
Such as, for the nginx server of load balancing, the quantity of testing server is increased or minimizing in test environment, thus change the quantity of the service request that every platform testing server receives, namely change the load of every platform testing server, thus detect each testing server response time to service request under different loads.
The size of the heap capacity of self and/or total thread stack can increase or reduce by each testing server, thus changes the disposal ability of testing server, judges whether to occur the problems such as RAM leakage.Under same memory, improve the size of total thread stack, then treatable Thread Count is more.Reduce heap capacity, frequently, then application program actual efficiency is lower for garbage reclamation, meanwhile, more easily occurs that heap memory overflows.In addition, also change the heap capacity in the youth generation of each testing server by Tiao Zheng – Xmn128m, select suitable Memory Allocation ratio.If due to the new object of the continuous instantiation of thread, deposit in internal memory, then internal memory use amount linearly increases, internal memory can be caused to overflow.In addition, when the resource in internal memory is not released, internal memory also can be caused to overflow.This kind of problem can be better exposed by reducing heap capacity.
Wherein ,-xmn128m refers to young for size.Whole JVM memory size be young for size, old generation size and lasting for size.In lasting generation, general fixed size was 64,000,000 (M), so increase young for after size, will reduce old generation size.This value is comparatively large on testing server performance impact, and recommended configuration is 3/8 of heap capacity.
For the application that the response time is preferential: establish large-xmn128m as far as possible, until be limited in such cases close to the minimum response time of system, the frequency that youth withholds collection generation is also minimum.Meanwhile, the object arriving old generation is reduced.
For the application that throughput is preferential: arrange large-xmn128m as much as possible, the degree of G bit may be arrived.Because to response time not requirement, refuse collection can walk abreast and carry out, the general application being applicable to 8 more than core CPU.
