以守護進程的方式啟動:
nohup sh bin/mqnamesrv & 這個命令可能會nohup: ignoring input and appending output to ‘nohup.out’,如果出現這個,執行:
tail -f nohup.out這個時候ctrl+c就不會退出程序,僅僅是讓程序后臺運行
啟動Broker
[root@wangzhi apache-rocketmq]# sh bin/mqbroker -n localhost:9876
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000005c0000000, 8589934592, 0) failed; error='Cannot allocate memory' (errno=12)

# There is insufficient memory for the Java Runtime Environment to continue.

# An error report file with more information is saved as:
# /usr/local/software/rocketmq/distribution/target/apache-rocketmq/hs_err_pid3012.log出現了Broker內存不足的問題:
vim bin/runbroker.sh 修改 JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g" 的內容為:
JAVA_OPT="${JAVA_OPT} -server -Xms2g -Xmx2g -Xmn1g"完成之后以守護進程的方式進行啟動:
nohup sh bin/mqbroker -n localhost:9876 &
tail -f nohup.out這個時候可以使用jps查看進程,并且可以根據進程號來kill進程
