Linux中nexus启动不起来
    #
    # There is insufficient memory for the Java Runtime Environment to continue.
    # Native memory allocation (mmap) failed to map 419430400 bytes for committing reserved memory.
    # Possible reasons:
    #   The system is out of physical RAM or swap space
    #   In 32 bit mode, the process size limit was hit
    # Possible solutions:
    #   Reduce memory load on the system
    #   Increase physical memory or swap space
    #   Check if swap backing store is full
    #   Use 64 bit Java on a 64 bit OS
    #   Decrease Java heap size (-Xmx/-Xms)
    #   Decrease number of Java threads
    #   Decrease Java thread stack sizes (-Xss)
    #   Set larger code cache with -XX:ReservedCodeCacheSize=

确认jdk版本,是否跟操作系统匹配,确定操作系统的内存, 设置jvm内存

linux下的nginx有启动方式,在nginx目录下有一个sbin目录,sbin目录下有一个nginx可执行程序。
执行 ./nginx
查看进程来判断nginx是否开启,命令ps -ef | grep nginx
