Tomcat 做成服务

增加tomcat.service文件

vim /usr/lib/systemd/system/tomcat.service

输入以下内容，并保存

[Unit]
Description=Tomcat
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/root/tomcat.pid
ExecStart=/root/apache-tomcat-8.0.33/bin/startup.sh 
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

终端执行：

systemctl enable tomcat.service

在tomcat的bin目录中增加文件

vim setenv.sh

输入以下内容

# add java home
export JAVA_HOME=/root/jdk1.8.0_77

测试

service tomcat start

redis 制作启动脚本

在/etc/init.d/增加redis文件

加入以下内容

#!/bin/sh
# chkconfig: 2345 10 90  
# description: Start and Stop redis   

### BEGIN INIT INFO
# Provides:          redis
# Required-Start:    $remote_fs $network
# Required-Stop:     $remote_fs $network
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts redis
# Description:       starts the redis FastCGI Process Manager daemon
### END INIT INFO


PATH=/usr/local/bin:/sbin:/usr/bin:/bin   
REDISPORT=6379  
EXEC=/root/redis-3.2.5/src/redis-server
#EXEC=/usr/local/bin/redis-server
REDIS_CLI=/root/redis-3.2.5/src/redis-cli   


PIDFILE=/run/redis_6379.pid
CONF="/root/redis-3.2.5/redis.conf"  
AUTH="1234"  

case "$1" in   
        start)   
                if [ -f $PIDFILE ]   
                then   
                        echo "$PIDFILE exists, process is already running or crashed."  
                else  
                        echo "Starting Redis server..."  
                        $EXEC $CONF   
                fi   
                if [ "$?"="0" ]   
                then   
                        echo "Redis is running..."  
                fi   
                ;;   
        stop)   
                if [ ! -f $PIDFILE ]   
                then   
                        echo "$PIDFILE exists, process is not running."  
                else  
                        PID=$(cat $PIDFILE)   
                        echo "Stopping..."  
                       $REDIS_CLI -p $REDISPORT  SHUTDOWN    
                        sleep 2  
                       while [ -x $PIDFILE ]   
                       do  
                                echo "Waiting for Redis to shutdown..."  
                               sleep 1  
                        done   
                        echo "Redis stopped"  
                fi   
                ;;   
        restart|force-reload)   
                ${0} stop   
                ${0} start   
                ;;   
        *)   
               echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2  
                exit 1  
esac

加入启动并设置权限

chkconfig redis on
chmod a+x /etc/init.d/redis

测试

/etc/init.d/redis start

activemq 制作服务

增加activemq.service

vim /usr/lib/systemd/system/activemq.service

插入以下内容

[Unit]
Description=Apache activemq
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/root/apache-activemq-5.13.2/data/activemq.pid
ExecStart=/root/apache-activemq-5.13.2/bin/activemq start
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

测试系统自启动

systemctl enable activemq.service

测试

service activemq start

Mycat 制作启动脚本

这个比较简单，直接将mycat/bin/mycat 做成链接到/etc/init.d/mycat

ln -s /root/mycat/bin/mycat /etc/init.d/mycat

测试

/etc/init.d/mycat start

设置自启动

需要修改mycat/conf/wrapper.conf需要将java改成绝对路径

#wrapper.java.command=java
wrapper.java.command=/root/jdk1.8.0_77/bin/java

再修改/etc/rc.local

在exit之前加入

/etc/init.d/mycat start

注意rc.local可能没有执行权限需要赋一下权限

chmod a+x /etc/rc.local

其它Java控制台程序

可以使用Maven的appassembler-maven-plugin的插件，制作成后台程序，之后就可以和Mycat一样了
