java - 无法使用 G1GC 启动 Solr

Question

我正在使用 Solr 7.7

我正在尝试使用 G1 GC 而不是默认的 CMS 启动我的 solr 服务器，但 solr 服务没有启动。

我用来启动 solr 的命令是

bin/solr start -p 8000 -a "-Dsolr.solr.home=<solrhomepath> -Denable.slave=true -Denable.master=false -XX:+UseG1GC -XX:MaxGCPauseMillis=500 -XX:+UnlockExperimentalVMOptions -XX:G1MaxNewSizePercent=30 -XX:G1NewSizePercent=5 -XX:G1HeapRegionSize=32M -XX:InitiatingHeapOccupancyPercent=70"

我通过删除/添加其他参数尝试了 start 命令的各种排列，但它不起作用。然而，只需启动就好了

"-Dsolr.solr.home=<solrhomepath> -Denable.slave=true -Denable.master=false"

并使用默认的 CMS 收集器启动

我也没有得到任何有用的错误日志。它等待默认的 180 秒，然后打印

Warning: Available entropy is low. As a result, use of the UUIDField, SSL, or any other features that require
RNG might not work properly. To check for the amount of available entropy, use 'cat /proc/sys/kernel/random/entropy_avail'.

Waiting up to 180 seconds to see Solr running on port 25280 [|]  Still not seeing Solr listening on 25280 after 180 seconds!
