使用自写脚本启动ES集群时，添加安全策略时报错如下：
Positional arguments not allowed, found [ -E xpack.security.enabled=true -E xpack.security.transport.ssl.enabled=true -E xpack.license.self_generated.type=basic -E xpack.security.transport.ssl.keystore.path=certs/elastic-certificates.p12 -E xpack.security.transport.ssl.truststore.path=certs/elastic-certificates.p12 -E xpack.security.transport.ssl.verification_mode=certificate]
if [[ $1 == 'security' ]]; thenecho '使用安全集群'shift 1ES_OPT=$@ES_OPT="$ES_OPT -E xpack.security.enabled=true -E xpack.security.transport.ssl.enabled=true -E xpack.license.self_generated.type=basic -E xpack.security.transport.ssl.keystore.path=certs/elastic-certificates.p12 -E xpack.security.transport.ssl.truststore.path=certs/elastic-certificates.p12 -E xpack.security.transport.ssl.verification_mode=certificate"
ficd $ES_HOME
for (( i = 0; i < $num; i++ )); doecho "尝试启动第`expr $i + 1`个ES节点"bin/elasticsearch -E node.name=node$i -E cluster.name=cluster -E path.data=node${i}_data $ES_OPT -d
done最后发现$ES_OPT为字符串处理，修改为数组处理
if [[ $1 == 'security' ]]; thenecho '使用安全集群'shift 1ES_OPT=$@ES_OPT=($ES_OPT[@] -Expack.security.enabled=true -Expack.security.transport.ssl.enabled=true -Expack.license.self_generated.type=basic -Expack.security.transport.ssl.keystore.path=certs/elastic-certificates.p12 -Expack.security.transport.ssl.truststore.path=certs/elastic-certificates.p12 -Expack.security.transport.ssl.verification_mode=certificate)

done
