wildfly jboss 优化配置
参考调优：http://www.mastertheboss.com/jboss-server/jboss-performance/jboss-as-7-performance-tuning?showall=1
1，jvm
\wildfly-10.0.0.Final\bin\standalone.conf.bat （linux standalone.conf）
set "JAVA_OPTS=-Xmx2048m -Xms2048m -XX:MaxNewSize=896m -XX:NewSize=896m -XX:SurvivorRatio=6 -XX:MetaspaceSize=256M -XX:MaxMetaspaceSize=2048m -XX:+UseLargePages "
2，log 日志
日志输出定义在root-logger里面：
<root-logger> <level name="INFO"/> <handlers> <handler name="CONSOLE"/> <handler name="FILE"/> </handlers> </root-logger>
级别是INFO;可以改为warn，error等减少日志输出。将<handler name="CONSOLE"/>删除掉，就不会往控制台输出日志。增快速度。
log将输出到两个handler里面：console和file。这两个定义如下：
<console-handler name="CONSOLE"> <level name="INFO"/> <formatter> <named-formatter name="COLOR-PATTERN"/> </formatter> </console-handler>
<size-rotating-file-handler name="FILE" autoflush="true"> <formatter> <named-formatter name="PATTERN"/> </formatter> <file relative-to="jboss.server.log.dir" path="server.log"/> <rotate-size value="1000k"/> <max-backup-index value="5"/> <append value="true"/> <suffix value=".yyyy-MM-dd"/> </size-rotating-file-handler>
文件用了size-rotating-file-handler。rotate-size规定了日志每达到1m，就生成新的日志。一天共会生成5个分割文件。当日志达到4个以后，剩下日志会全填充到server.log。导致这个转为.5文件后特别大。
3. 数据库连接池失败后，自动重新连接
<datasource jndi-name="java:jboss/datasources/MySqlDS" pool-name="MySqlDS" enabled="true" use-java-context="true"> <connection-url>jdbc:mysql://localhost:3306/statisticsystem?characterEncoding=utf-8&autoReconnect=true&failOverReadOnly=false</connection-url> <driver>mysql</driver> <security> <user-name>jboss</user-name> <password>jboss</password> </security> <validation> <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker"/> <validate-on-match>true</validate-on-match> <background-validation>false</background-validation> </validation> <timeout> <set-tx-query-timeout>false</set-tx-query-timeout> <blocking-timeout-millis>0</blocking-timeout-millis> <idle-timeout-minutes>0</idle-timeout-minutes> <query-timeout>0</query-timeout> <use-try-lock>0</use-try-lock> <allocation-retry>0</allocation-retry> <allocation-retry-wait-millis>0</allocation-retry-wait-millis> </timeout> <statement> <share-prepared-statements>false</share-prepared-statements> </statement> </datasource>
<xa-datasource jndi-name="java:jboss/datasources/MySqlStatDW" pool-name="MySqlStatDW" enabled="true" use-java-context="true"> <xa-datasource-property name="ServerName"> 192.168.8.238 </xa-datasource-property> <xa-datasource-property name="PortNumber"> 5029 </xa-datasource-property> <xa-datasource-property name="DatabaseName"> statistics </xa-datasource-property> <driver>mysql</driver> <xa-pool> <min-pool-size>5</min-pool-size> <initial-pool-size>5</initial-pool-size> <max-pool-size>100</max-pool-size> <prefill>true</prefill> </xa-pool> <security> <user-name>zhibin</user-name> <password>zhibin123</password> </security> <validation> <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker"/> <check-valid-connection-sql>SELECT 1</check-valid-connection-sql> <validate-on-match>true</validate-on-match> <background-validation>false</background-validation> <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter"/> </validation> <statement> <share-prepared-statements>false</share-prepared-statements> </statement> </xa-datasource> <xa-datasource jndi-name="java:jboss/datasources/MySqlDataCenter" pool-name="MySqlDataCenter" enabled="true" use-java-context="true"> <xa-datasource-property name="ServerName"> 211.100.75.213 </xa-datasource-property> <xa-datasource-property name="DatabaseName"> cms </xa-datasource-property> <driver>mysql</driver> <xa-pool> <min-pool-size>5</min-pool-size> <initial-pool-size>5</initial-pool-size> <max-pool-size>100</max-pool-size> <prefill>true</prefill> </xa-pool> <security> <user-name>CPdeveloper206</user-name> <password>206@)^developer</password> </security> </xa-datasource>
?characterEncoding=utf-8 是数据库存中文乱码，加上后改好。（注意：创建schema或者table时候指定字符集是utf8）
4，事务的超时
<subsystem xmlns="urn:jboss:domain:transactions:3.0"> <core-environment> <process-id> <uuid/> </process-id> </core-environment> <recovery-environment socket-binding="txn-recovery-environment" status-socket-binding="txn-status-manager"/> <coordinator-environment default-timeout="60"/> </subsystem>
5，任务job，分区任务最大的线程数
<subsystem xmlns="urn:jboss:domain:batch-jberet:1.0"> <default-job-repository name="in-memory"/> <default-thread-pool name="batch"/> <job-repository name="in-memory"> <in-memory/> </job-repository> <thread-pool name="batch"> <max-threads count="200"/> <keepalive-time time="30" unit="seconds"/> </thread-pool> </subsystem>
6，数据库做http auth
<security-domain name="dbdomain" cache-type="default"> <authentication> <login-module code="Database" flag="required"> <module-option name="dsJndiName" value="java:jboss/datasources/MySqlDS"/> <module-option name="principalsQuery" value="select passwd from USERS where login=?"/> <module-option name="rolesQuery" value="select Role , 'Roles' from USER_ROLES where login=?"/> </login-module> </authentication> </security-domain>
7，上传文件最大尺寸限制
<server name="default-server"> <http-listener name="default" max-post-size="204857600" socket-binding="http" redirect-socket="https"/>
8，改成外网地址可以访问
<interfaces> <interface name="management"> <inet-address value="${jboss.bind.address.management:0.0.0.0}"/> </interface> <interface name="public"> <inet-address value="${jboss.bind.address:0.0.0.0}"/> </interface> <interface name="unsecure"> <inet-address value="${jboss.bind.address.unsecure:127.0.0.1}"/> </interface> </interfaces>
