前言

安装常见问题
问题1：

[root@iZwz95j86y235aroi85ht0Z bin]# ./jmeter-server
Created remote object: UnicastServerRef2 [liveRef: [endpoint:[:39308](local),objID:[24e78a63:16243c70661:-7fff, 7492480871343944173]]]
Server failed to start: java.rmi.RemoteException: Cannot start. Unable to get local host IP address.; nested exception is:
java.net.UnknownHostException: iZwz95j86y235aroi85ht0Z: iZwz95j86y235aroi85ht0Z: Name or service not known
An error occurred: Cannot start. Unable to get local host IP address.; nested exception is:
java.net.UnknownHostException: iZwz95j86y235aroi85ht0Z: iZwz95j86y235aroi85ht0Z: Name or service not known

解决：
hostname 命令获取机器名称，追加一个映射 iZwz95j86y235aroi85ht0Z

vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
120.79.160.143 iZwz95j86y235aroi85ht0Z

windows用户修改c:\windows\system32\drivers\etc\hosts文件，增加一条域名与IP的映射

问题2：

[root@iZwz95j86y235aroi85ht0Z bin]# ./jmeter-server
Server failed to start: java.rmi.server.ExportException: Listen failed on port: 0; nested exception is:
java.io.FileNotFoundException: rmi_keystore.jks (No such file or directory)
An error occurred: Listen failed on port: 0; nested exception is:
java.io.FileNotFoundException: rmi_keystore.jks (No such file or directory)

解决：
拥有RMI over SSL的有效密钥库，或者禁用了SSL。

禁用SSL
jmeter.property里面 server.rmi.ssl.disable 改为 true，表示禁用

问题3：

[root@userCenter bin]# ./jmeter-server
Created remote object: UnicastServerRef2 [liveRef: [endpoint:[127.0.0.1:39687](local),objID:[-18db419a:167773db861:-7fff, -176377700206527642]]]
Server failed to start: java.rmi.RemoteException: Cannot start. userCenter is a loopback address.
An error occurred: Cannot start. userCenter is a loopback address.

解决：
执行时加上参数./jmeter-server -Djava.rmi.server.hostname=10.1.1.222

问题4：

[root@iZ949uw2xehZ bin]# ./jmeter
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c0000000, 1073741824, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 1073741824 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /usr/local/jmeter/apache-jmeter-4.0/bin/hs_err_pid5855.log

解决：
编辑jmeter
搜索 : “${HEAP:=”-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m"}"
改变初始堆内存和最大堆内存

仅修改 server_port 即可，下面两者一样

server.rmi.localport=8899 表示slave server启动显示的端口
server_port=8899 表示master机器要远程连接的端口即 remote_hosts=xxxx:8899

jmeter 分布式性能测试（多网卡配置）

我们要在多网卡的服务器上开启RMI服务的话必须指定IP，使他们能够在同一个网段内。

需要以下几步（假定所有机器都在10.120.11.*网段,agent服务器为linux,controller服务器为windows）：

修改agent服务器，指定agent机器的IP
1)修改jmeter-server文件
