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&amp;autoReconnect=true&amp;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>

                    <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

                    </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

                    </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>
