Java HotSpot(TM) Server VM warning: You have loaded library /wostore/sonar/sonarqube-6.7.6/bin/linux-x86-64/lib/libwrapper.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

WARNING - Unable to load the Wrapper's native library 'libwrapper.so'.
          The file is located on the path at the following location but
          could not be loaded:
            /wostore/sonar/sonarqube-6.7.6/bin/linux-x86-64/./lib/libwrapper.so
          Please verify that the file is readable by the current user
          and that the file has not been corrupted in any way.
          One common cause of this problem is running a 32-bit version
          of the Wrapper with a 64-bit version of Java, or vica versa.
          This is a 32-bit JVM.
          Reported cause:
            /wostore/sonar/sonarqube-6.7.6/bin/linux-x86-64/lib/libwrapper.so: /wostore/sonar/sonarqube-6.7.6/bin/linux-x86-64/lib/libwrapper.so: wrong ELF class: ELFCLASS64 (Possible cause: architecture word width mismatch)
          System signals will not be handled correctly.

切换到root用户

执行命令：

sysctl -w vm.max_map_count=262144

查看结果：

sysctl -a|grep vm.max_map_count

显示：

vm.max_map_count = 262144

上述方法修改之后，如果重启虚拟机将失效，所以：

解决办法：

在   /etc/sysctl.conf文件最后添加一行

vm.max_map_count=262144

即可永久修改
