luci+nginx高可用集群配置

配置环境：
节点1：server1（172.25.62.1）
节点2：server2（172.25.62.4）
real server1（172.25.62.2）
real server2（172.25.62.3）

一、RS配置：

下载httpd服务，并修改默认发布录文件，打开httpd服务
这里写图片描述

二、nginx配置

server1和server4配置ngnix服务，配置方法在：

为了在luci管理器上用执行脚本执行，所以需要编辑nginx的执行脚本
vim nginx

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /usr/local/nginx/conf/nginx.conf
# pidfile:     /usr/local/nginx/logs/nginx.pid

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0

nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)

lockfile="/var/lock/subsys/nginx"
pidfile="/usr/local/nginx/logs/${prog}.pid"

NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"


start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}

stop() {
    echo -n $"Stopping $prog: "
    killproc -p $pidfile $prog
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}

restart() {
    configtest_q || return 6
    stop
    start
}

reload() {
    configtest_q || return 6
    echo -n $"Reloading $prog: "
    killproc -p $pidfile $prog -HUP
    echo
}

configtest() {
    $nginx -t -c $NGINX_CONF_FILE
}

configtest_q() {
    $nginx -t -q -c $NGINX_CONF_FILE
}

rh_status() {
    status $prog
}

rh_status_q() {
    rh_status >/dev/null 2>&1
}

# Upgrade the binary with no downtime.
upgrade() {
    local oldbin_pidfile="${pidfile}.oldbin"

    configtest_q || return 6
    echo -n $"Upgrading $prog: "
    killproc -p $pidfile $prog -USR2
    retval=$?
    sleep 1
    if [[ -f ${oldbin_pidfile} && -f ${pidfile} ]];  then
        killproc -p $oldbin_pidfile $prog -QUIT
        success $"$prog online upgrade"
        echo 
        return 0
    else
        failure $"$prog online upgrade"
        echo
        return 1
    fi
}

# Tell nginx to reopen logs
reopen_logs() {
    configtest_q || return 6
    echo -n $"Reopening $prog logs: "
    killproc -p $pidfile $prog -USR1
    retval=$?
    echo
    return $retval
}

case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart|configtest|reopen_logs)
        $1
        ;;
    force-reload|upgrade) 
        rh_status_q || exit 7
        upgrade
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    status|status_q)
        rh_$1
        ;;
    condrestart|try-restart)
        rh_status_q || exit 7
        restart
        ;;
    *)
        echo $"Usage: $0 {start|stop|reload|configtest|status|force-reload|upgrade|restart|reopen_logs}"
        exit 2
esac

server1和server4都需要操作
复制到/etc/init.c/下并给到执行权限

3、ricci节点配置

在server1和server4安装ricci服务
并将服务打开，开启开机自启动

4、luci管理节点设置

将管理节点设置在server1上

yum install luci -y

打开luci服务

5、在luci的web页面配置

luciweb页面配置详情：
https://blog.csdn.net/weixin_41789003/article/details/80809365
将之前的httpd服务删除，或者停掉
这里写图片描述

在luci节点管理工具查看

[root@server1 init.d]# clustat

 service:web                    server1                        started

当server1的nginx停掉之后，

[root@server1 init.d]# clustat 
Cluster Status for westos_hwj @ Thu Jun 28 11:32:58 2018
Member Status: Quorate

 server4                                     2 Online, rgmanager

 service:web                    server4                        starting

且vip自动被4接管
