下载log4j2.17
下载地址：Apache Logging Serviceshttps://logging.apache.org/

查找es安装目录下需要替换的log4j文件

/opt/elk# find . -name log4j*
./elasticsearch-7.2.0/lib/log4j-api-2.11.1.jar
./elasticsearch-7.2.0/lib/log4j-core-2.11.1.jar
./elasticsearch-7.2.0/lib/log4j-1.2-api-2.11.1.jar
./elasticsearch-7.2.0/modules/x-pack-security/log4j-slf4j-impl-2.11.1.jar
./elasticsearch-7.2.0/config/log4j2.properties

备份旧文件

#四个需要替换的旧文件
./elasticsearch-7.2.0/lib/log4j-api-2.11.1.jar
./elasticsearch-7.2.0/lib/log4j-core-2.11.1.jar
./elasticsearch-7.2.0/lib/log4j-1.2-api-2.11.1.jar
./elasticsearch-7.2.0/modules/x-pack-security/log4j-slf4j-impl-2.11.1.jar

将2.11.1文件替换为2.17.2

./elasticsearch-7.2.0/lib/log4j-1.2-api-2.17.2.jar
./elasticsearch-7.2.0/lib/log4j-api-2.17.2.jar
./elasticsearch-7.2.0/lib/log4j-core-2.17.2.jar
./elasticsearch-7.2.0/modules/x-pack-security/log4j-slf4j-impl-2.17.2.jar

修改替换的文件权限

chown -R esuser:esgroup ./elasticsearch-7.2.0/lib/log4j-1.2-api-2.17.2.jar
chown -R esuser:esgroup ./elasticsearch-7.2.0/lib/log4j-api-2.17.2.jar
chown -R esuser:esgroup ./elasticsearch-7.2.0/lib/log4j-core-2.17.2.jar
chown -R esuser:esgroup ./elasticsearch-7.2.0/modules/x-pack-security/log4j-slf4j-impl-2.17.2.jar

权限给到es用户

重新启动
