如何自动启动Solr？

此刻我必须去/usr/java/apache-solr-1.4.0/example然后执行以下操作：

java -jar start.jar

如何让它在启动时自动启动？

我在共享 Linux 服务器上。

当您使用共享 Linux 机器时，您可能必须要求系统管理员执行以下操作。

在中创建启动脚本/etc/init.d/solr.

将此代码（我的 Solr 启动脚本）复制到该文件中：

#!/bin/sh

# Prerequisites:
# 1. Solr needs to be installed at /usr/local/solr/example
# 2. daemon needs to be installed
# 3. Script needs to be executed by root

# This script will launch Solr in a mode that will automatically respawn if it
# crashes. Output will be sent to /var/log/solr/solr.log. A PID file will be
# created in the standard location.

start () {
    echo -n "Starting solr..."

    # Start daemon
    daemon --chdir='/usr/local/solr/example' --command "java -jar start.jar" --respawn --output=/var/log/solr/solr.log --name=solr --verbose

    RETVAL=$?
    if [ $RETVAL = 0 ]
    then
        echo "done."
    else
        echo "failed. See error code for more information."
    fi
    return $RETVAL
}

stop () {
    # Stop daemon
    echo -n "Stopping solr..."

    daemon --stop --name=solr  --verbose
    RETVAL=$?

    if [ $RETVAL = 0 ]
    then
        echo "Done."
    else
        echo "Failed. See error code for more information."
    fi
    return $RETVAL
}


restart () {
    daemon --restart --name=solr  --verbose
}


status () {
    # Report on the status of the daemon
    daemon --running --verbose --name=solr
    return $?
}


case "$1" in
    start)
        start
    ;;
    status)
        status
    ;;
    stop)
        stop
    ;;
    restart)
        restart
    ;;
    *)
        echo $"Usage: solr {start|status|stop|restart}"
        exit 3
    ;;
esac

exit $RETVAL

然后运行：

chkconfig --添加 solr

或者（在 Ubuntu 上）：

update-rc.d solr 默认值

...或者，如果您的 Linux 发行版没有chkconfig (or update-rc.d), link /etc/init.d/solr to /etc/rc3.d/S99solr and /etc/rc5.d/S99solr and /etc/rc3.d/K01solr and /etc/rc5.d/K01solr:

% ln -s /etc/init.d/solr /etc/rc3.d/S99solr

% ln -s /etc/init.d/solr /etc/rc5.d/S99solr

% ln -s /etc/init.d/solr /etc/rc3.d/K01solr

% ln -s /etc/init.d/solr /etc/rc5.d/K01solr

现在重新启动时，Solr 将以运行级别 3 和 5 启动（带有网络和完整的控制台）GUI).

要手动启动 solr，请运行：

% /etc/init.d/solr start
