集群安装

本文使用版本为 ignite v2.8.1

集群配置

默认安装 jdk 1.8 版本即可，集群每台主机上的 $IGNITE_HOME/config 目录下增加 default.xml 配置文件如下：

注 创建数据存放目录 mkdir -p /data/ignite/{storage,walArchive,wal}

启动集群

在每台集群主机上执行如下命令即可

# 安装 jdk 1.8
$ wget http://repo.hdp.com/jdk-8u211-linux-x64.tar.gz
$ tar xvf jdk-8u211-linux-x64.tar.gz
$ mkdir -p /usr/jdk64 && mv jdk1.8.0_211 /usr/jdk64/

# 添加环境变量
$ echo "export JAVA_HOME=/usr/jdk64/jdk1.8.0_211" >> /etc/profile
$ echo "export IGNITE_HOME=/root/apache-ignite" >> /etc/profile

# 启动服务
$ ./bin/ignite.sh config/default.xml &

# 激活
$ ./bin/control.sh --user ignite --password ignite --activate

# 查看状态
$ ./bin/control.sh --user ignite --password ignite --state

# 查看集群基线
$ ./bin/control.sh --user ignite --password ignite --baseline

# 从集群中手动删除节点
$ ./bin/control.sh --user ignite --password ignite --baseline remove 75a706e0-f40f-4418-84d9-93e06b853e45

# 使用 sqlline 访问数据库，用户名默认为 ignite/ignite
$ ./bin/sqlline.sh --color=true --verbose=true -n ignite -p ignite -u jdbc:ignite:thin://172.19.3.97,172.19.3.98,172.19.3.99/

注 务必关闭服务器防火墙，否则会出现集群找不到其他节点信息

注 优化参考方案：

常见问题

配置不一样导致 Remote node has peer class loading enabled flag different from local [locId8=d9ec5b41, locPeerClassLoading=true, rmtId8=3d11ed2e, rmtPeerClassLoading=false

注 将所有配置改为一致即可, 上述错误主要由于 peerClassLoadingEnabled = true 选项导致

注 配置不一致也会导致如下错误：Caused by: class org.apache.ignite.spi.IgniteSpiException: BaselineTopology of joining node (2af934c1-1936-4c2b-8368-7107a22045fc) is not compatible with BaselineTopology in the cluster. Branching history of cluster BlT ([953524018]) doesn't contain branching point hash of joining node BlT (310856721). Consider cleaning persistent storage of the node and adding it to the cluster again.

通过组播网络进行配置

                </property>
            </bean>
        </property>
    </bean>
</property>

通过 zookeeper 进行配置

<property name="discoverySpi">
     <bean class="org.apache.ignite.spi.discovery.zk.ZookeeperDiscoverySpi">
      <!-- zookeeper ip 地址 -->
      <property name="zkConnectionString" value="172.8.4.75:2181"/>
      <property name="sessionTimeout" value="30000"/>
      <!-- zookeeper 内 node 名称 -->
      <property name="zkRootPath" value="/apacheIgnite"/>
      <property name="joinTimeout" value="10000"/>
     </bean>
</property>

GC 优化

在 bin/ignite.sh 脚本中，对 JVM GC 进行优化如下：

#
# JVM options. See http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp for more details.
#
# ADD YOUR/CHANGE ADDITIONAL OPTIONS HERE
#
if [ -z "$JVM_OPTS" ] ; then
# heap 过大会造成 gc 时间过长，选取个合适的大小即可
    JVM_OPTS="-Xms10g -Xmx10g -Xmn6g -server -XX:MaxMetaspaceSize=8G"
    # 注 -XX:MaxDirectMemorySize = walSegmentSize * 4, 参考 [durable-memory-tuning](https://apacheignite.readme.io/docs/durable-memory-tuning)
    JVM_OPTS="-XX:MaxDirectMemorySize=4G"
fi

#
# Uncomment the following GC settings if you see spikes in your throughput due to Garbage Collection.
# -XX:+AlwaysPreTouch               减少新生代晋升到老年代时停顿
# -XX:+ScavengeBeforeFullGC    年轻代GC优于Full GC执行
# -XX:+DisableExplicitGC             不响应 System.gc() 代码
#
JVM_OPTS="$JVM_OPTS -XX:+UseG1GC"
JVM_OPTS="$JVM_OPTS -XX:+AlwaysPreTouch -XX:+ScavengeBeforeFullGC -XX:+DisableExplicitGC -XX:MaxGCPauseMillis=200 -XX:InitiatingHeapOccupancyPercent=45 "

#
# GC logs
#
JVM_OPTS="$JVM_OPTS -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=../heapdump -XX:+ExitOnOutOfMemoryError"
JVM_OPTS="$JVM_OPTS -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps -XX:+PrintAdaptiveSizePolicy"
JVM_OPTS="$JVM_OPTS -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=100M -Xloggc:../gc.log"

系统优化内容如下：

如果GC日志显示：low user time, low system time, long GC pause，那么一个原因就是 GC 线程因为内核等待 I/O 而卡住了，发生的原因基本是日志提交或者因为日志滚动的 gzip 导致改变的文件系统刷新。

# 增加页面刷新到磁盘的频率，从默认的30秒到5秒
sysctl -w vm.dirty_writeback_centisecs=500
sysctl -w vm.dirty_expire_centisecs=500

# 检查并且降低‘swappiness’的设定来保护堆和匿名内存
sysctl -w vm.swappiness=10

# 关闭NUMA zone-reclaim优化
sysctl -w vm.zone_reclaim_mode=0

# 关闭transparent_hugepage
echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag

# 避免内存页面直接回收导致的长时间GC暂停，在Linux的最新内核版本中，
# 可以通过/proc/sys/vm/extra_free_kbytes设置
# 在wmark_min和wmark_low之间增加额外的字节来避免前述的延迟
sysctl -w vm.extra_free_kbytes=1240000

上述代码节选至 Apache Ignite 2.3使用例子与问题总结

压缩包安装

注 ignite-compress 模块使能，需执行 cp $IGNITE_HOME/libs/optional/ignite-compress $IGNITE_HOME/libs/ 进行压缩模块安装

参考 wal 日志使能

monit 保证服务稳定

在 /etc/monit.d/services.cfg 文件里追加如下内容即可：

check process ignite
    matching "org.apache.ignite.startup.cmdline.CommandLineStartup"
    start program = "/root/apache-ignite/bin/ignite.sh /root/apache-ignite/config/default-config.xml"
    stop program = "/bin/bash -c 'kill -s SIGTERM `ps -ef | grep org.apache.ignite.startup.cmdline.CommandLineStartup | grep -v grep | awk -F" " '{print $2}'`'"

使用 centos 服务及 monit 保证服务稳定运行

编辑 vi /etc/systemd/system/ignite.service ，添加如下内容：

[Unit]
Description=Apache Ignite Service
After=network.target

[Service]
Type=simple
WorkingDirectory="/root/apache-ignite"
PrivateDevices=yes
ProtectSystem=full
ExecReload=/bin/kill -HUP $MAINPID
KillMode=mixed
KillSignal=SIGTERM
TimeoutStopSec=10
ExecStart="/root/apache-ignite/bin/ignite.sh"
SyslogIdentifier=Ignite
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target
Alias=ignite.service

执行 systemctl daemon-reload 加载服务，接下来修改 /etc/monit.d/services.cfg 配置文件并加载监控 monit reload 即可：

check process ignite
    matching "org.apache.ignite.startup.cmdline.CommandLineStartup"
    start program  "/usr/bin/systemctl start ignite.service"
    stop program  "/usr/bin/systemctl stop ignite.service"

新增设备报 IgniteCheckedException 异常

在启动参数中添加 -DIGNITE_SKIP_CONFIGURATION_CONSISTENCY_CHECK=true 参数即可
