ejabberd和客户端的配置

ejabberd

web通讯的开源软件ejabberd,优点:扩展性好,可以集群,支持web客户端

服务端安装:
    1.下载bin文件,执行就可以了.
    2.从源码开始安装,附属文档比较全面.推荐!
        安装过程看源码包里的安装文档就ok
客户端安装:
    1.桌面程序有psi
    2.web客户端有很多
服务端配置:
    主配置文件: ejabberd.cfg

{loglevel, 5}.-------------------------  debug  log的级别
{hosts, ["apache.yizhong.com"]}.-------  域名
{listen,  -----------------------------  监听
 [
  {5222, ejabberd_c2s, [---------------  5222    client to server 的端口
                        {access, c2s},
                        {shaper, c2s_shaper},
                        {max_stanza_size, 65536}
                       ]},
  {5269, ejabberd_s2s_in, [
                           {shaper, s2s_shaper},
                           {max_stanza_size, 131072}
                          ]},
  {5280, ejabberd_http, [--------------   管理端口,web界面
                         http_bind,
                         http_poll,
                         web_admin
                        ]}
 ]}.
{auth_method, odbc}.  -----------------   登陆的认证方法,此为数据库
{odbc_server, {pgsql, "localhost", 5432, "ejabberd", "postgres", ""}}. ------- 用pgsql做认证
{pgsql_users_number_estimate, true}.--------  优化pgsql的统计选项
{shaper, normal, {maxrate, 1000}}.
{shaper, fast, {maxrate, 50000}}.
{acl, admin, {user, "admin", "apache.yizhong.com"}}.
{acl, local, {user_regexp, ""}}.
{access, max_user_sessions, [{100, all}]}.
{access, local, [{allow, local}]}.
{access, c2s, [{deny, blocked},
               {allow, all}]}.

{access, muc, [{allow, all}]}.
{access, register, [{allow, all}]}.
{access, pubsub_createnode, [{allow, all}]}.
{language, "en"}.
{modules,-----------------------------------虚拟主机加载的公共模块,还可以加载其他模块
 [
  {mod_adhoc,    []},
  {mod_caps,     []},
  {mod_disco,    []},
  {mod_http_bind,[]},
  {mod_http_fileserver, [{docroot, "/opt/ejabberd-2.0.2_2/www"}]},
  {mod_irc,      []},
  {mod_last,     []},
  {mod_muc,      [
                  {access, muc},
                  {access_create, muc},
                  {access_persistent, muc},
                  {access_admin, muc_admin}
                 ]},
  {mod_offline,  []},
  {mod_privacy,  []},
  {mod_private,  []},
                  {access_createnode, pubsub_createnode},
                  {plugins, ["default", "pep"]}
                 ]},
  {mod_register, [
                  {welcome_message, {"Welcome!",
                                     "Welcome to this Jabber server."}},
                  {access, register}
                 ]},
  {mod_roster,   []},
  {mod_shared_roster,[]},

 ]}.

配置pgsql连接:

{auth_method, odbc}.  -----------------   登陆的认证方法,此为数据库
{odbc_server, {pgsql, "localhost", 5432, "ejabberd", "postgres", ""}}. ------- 用pgsql做认证
{pgsql_users_number_estimate, true}.--------  优化pgsql的统计选项

这3项必有
在源码包中有pg.sql文件,在psql客户端中执行这个文件
进入pgsql:
psql -U postgres template1

执行pg.sql文件建立数据库和表:
postgres#\i /----path---/pg.sql

之后,在postgresql中新建个数据库ejabberd

退出psql,进入ejabberd数据库:
psql -U postgres ejabberd

\dt
就能看到新建立的表了

注意:  连接数据库的几个要点,
    pgsql --> 关键字
    host --> "localhost"
    端口 --> 5432   不用加引号
    数据库名字 --> "ejabberd"
    用户名 --> "postgres"
    密码 --> "" 这里为空

    还有其他的配置文件要看看,如conf文件夹里的odbcini, odbcinst.ini,里面也有用户名和密码等要点.注意要和ejabberd.cfg一致

web客户端和服务端的通讯:
用apache中转下,做个映射才可以.当然,apache要开proxy模块了;下面是apache的虚拟主机的配置:
<VirtualHost *:80>
  ServerName ezsoft
  DocumentRoot "d:/web/"
  <Directory "d:/web/">
    Options +MultiViews
  </Directory>
  AddDefaultCharset UTF-8
  ProxyPass /http-bind/ http://192.168.3.196:5280/http-bind/-----------> 这里!
</VirtualHost>
