ES脚本启动报错修改

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 [[ $1 == 'security' ]]; then
    echo '使用安全集群'
    shift 1
    ES_OPT=$@
    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"
fi
 
cd $ES_HOME
for (( i = 0; i < $num; i++ )); do
    echo "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 [[ $1 == 'security' ]]; then
    echo '使用安全集群'
    shift 1
    ES_OPT=$@
    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)
fi
 
cd $ES_HOME
for (( i = 0; i < $num; i++ )); do
    echo "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
