freeswitch-1.10.1负载均衡之opensips-2.4.6

1. 安装mysql依赖库
    apt-get install libmysql++-dev

2. 下载openSIPS
    https://opensips.org/pub/opensips/2.4.6/opensips-2.4.6.tar.gz

3. 编译及安装openSIPS
    make all include_modules="db_mysql"
    make include_modules="db_mysql" prefix=/opt/opensips install

4. 修改opensipsctlrc
    DBENGINE=MYSQL
    DBPORT=3306
    DBHOST=192.168.129.172
    DBNAME=opensips
    DBRWUSER=opensips   ——对于mysql-5.7.X，该值可以是opensips；但mysql-8.x版本需要在mysql中创建相应的用户才可，该处用户为myroot
    DBRWPW="gs123456" —— opensips数据库的密码
    DBROOTUSER="myroot"

5. 创建openSIPS数据库
    opensipsdbctl create

6. 配置呼叫负载均衡
    /*!
        probe_mode该字段启动负载均衡服务器的保活功能，如果其中一个进行宕机，则opensips不会再向其路由呼叫
        vm：表示最大支持100路VoiceMail
        conf：表示最大支持100路会议室
        transc：表示最大支持100路转码
        pstn：表示最大支持500路普通呼叫（PSTN呼叫）
    */
    insert into load_balancer (group_id, dst_uri, resources, probe_mode, description) values (1,'sip:192.168.129.8', 'vm=100;conf=100;transc=100;pstn=500', 2, 'FS1');
    insert into load_balancer (group_id, dst_uri, resources, probe_mode, description) values (1,'sip:192.168.129.164', 'vm=100;conf=100;transc=100;pstn=500', 2, 'FS2');
 

7. 编辑配置文件opensips.cfg
    log_level=0
    log_stderror=no
    log_facility=LOG_LOCAL0

    children=1

    children=4

    dns_try_ipv6=no

    auto_aliases=no

    listen=udp:192.168.129.124:5060

    ####### Routing Logic ########
    route {
        if (!mf_process_maxfwd_header("10")) {
            sl_send_reply("483","Too Many Hops");
            exit;
        }

        if (!has_totag()) {
            # initial request
            record_route();
        } else {
            # sequential request - obey the indicated route
            loose_route();
            t_relay();
            exit;
        }

        # handle cancel and re-transmissions
        if (is_method("CANCEL")) {
            if (t_check_trans())
                t_relay();
            exit;
        }

        # from now on we have only the initial requests

        # select the node that'll handle the call (load balanced)
        # the method used is different for invite/register requests
        # unknown methods are rejected here
        if (is_method("INVITE")) {
            if (!load_balance("1","pstn","1")) {
                send_reply("503","Service Unavailable");
                exit;
            }
        } else if (is_method("REGISTER")) {
            if (!ds_select_dst("1", "4")) {
                send_reply("503","Service Unavailable");
                exit;
            }
        } else {
            send_reply("405","Method Not Allowed");
            exit;
        }

        # route the request
        if (!t_relay()) {
            sl_reply_error();
        }
    }

8. 配置dispatcher（register）路由表
    opensipsctl dispatcher addgw 1 sip:192.168.129.8 '' 0 'FS1' 'Outbound Gateway1'
    opensipsctl dispatcher addgw 1 sip:192.168.129.164 '' 0 'FS2' 'Outbound Gateway2'

9. openSIPS LB控制命令opensipsctl
    opensipsctl fifo lb_list   ——列出当前opensips LB状态信息
    opensipsctl fifo lb_reload ——重载opensips LB配置信息
