ejabberd服务端***：
一：配置出错
[root@ce ejabberd]# ./configure.sh
checking whether make sets $(MAKE)... yes
checking for a BSD-compatible install... /usr/bin/install -c
checking for a sed that does not truncate output... /bin/sed
checking for erl... /usr/local/bin/erl
checking for erlc... /usr/local/bin/erlc
checking for erl... /usr/local/bin/erl
checking for erlc... /usr/local/bin/erlc
checking Erlang/OTP version... {"init terminating in
do_boot",{function_clause,[{conftest,less_or_equal,[[1],[]],[{file,"conftest.erl"},{line,40}]},{conftest,check,2,[{file,"conftest.erl"},{line,30}]},{conftest,start,0,[{file,"conftest.erl"},{line,12}]},{init,start_it,1,[]},{init,start_em,1,[]}]}}
Crash dump was written to: erl_crash.dump
init terminating in do_boot ()
configure.sh: error: "Could not run Erlang/OTP version check
program using '/usr/local/bin/erl'"
二：修改配置
修改configure中less_or_equal方法
&less_or_equal(_, _) -&
%%less_or_equal([], []) -&
%%less_or_equal([Left| Rl], [Right| Rr]) -&
%%&&& case {Left
& Right, Left == Right} of
{true, _}& -&
%%&&&&&&&&&&&
{false, false} -&
%%&&&&&&&&&&&
{false, true} -&
%%&&&&&&&&&&&
less_or_equal(Rl, Rr)
%%&&& end.
三：检查***rebar
四，***rebar
/basho/rebar
unzip rebar-master.zip
cd rebar-master
&./bootstrap
Congratulations! You now have a self-contained script called
"rebar" in
your current working directory. Place this script anywhere in your
and you can use rebar to build OTP-compliant apps.
上面那句为***完后提示语，建立连接，
cd /usr/local/bin
ln -s /data/dengke/rebar-master/rebar rebar
rebar更详细参考另一篇rebar相关
五，make时报错
[root@ce ejabberd]# make
rm -rf deps/.got
rm -rf deps/.built
/usr/local/lib/erlang/bin/escript rebar get-deps
==& rel (get-deps)
==& ejabberd (get-deps)
Pulling p1_cache_tab from
{git,"git:///processone/cache_tab"}
ERROR: Rebar requires version {1,5} or higher of git to process
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
"git:///processone/cache_tab"}
ERROR: 'get-deps' failed while processing /mnt/hgfs/ejabberd:
rebar_abort
make: *** [deps/.got] Error 1
***git，相关可参考另一篇rebar相关
六，解决make报错
ejabberd 有个相关rebar.config.script配置文件，
Deps = [{p1_cache_tab, ".*", {git,
"git:///processone/cache_tab"}},
{p1_tls, ".*", {git, "git:///processone/tls"}},
{p1_stringprep, ".*", {git,
"git:///processone/stringprep"}},
{p1_xml, ".*", {git, "git:///processone/xml"}},
{p1_yaml, ".*", {git,
"git:///processone/p1_yaml"}},
{xmlrpc, ".*", {git, "git:///rds13/xmlrpc"}}],
里面有个p1_yaml这个依赖项目，p1_yaml这个又需要先***libyaml
下载 git:///processone/p1_yaml，里面README.md提到P1 YAML is an
Erlang wrapper for [libyaml](http://pyyaml.org/wiki/LibYAML) "C"
library.，所以要先***libyaml
Download and Installation

七，make install
启动可参考:http://www.process-one.net/docs/ejabberd/guide_en.pdf
八，启动报错
ejabberdctl live
[error] unable to load p1_yaml NIF: {error,{load_failed,"Failed to
load NIF library /lib/ejabberd/priv/lib/p1_yaml: 'libyaml-0.so.2:

（1）：***LibYAML:
下载：http://pyyaml.org/wiki/LibYAML
./configure && make
&& make install
***后还是报错
卸载 ： make uninstall
（2）：RPM***64位：
下载：http://rpm.pbone.net/index.php3/stat/4/idpl//dir/centos_5/com/libyaml-0-2-0.1.4-2.1.x86_64.rpm.html
rpm -i libyaml-0-2-0.1.4-2.1.x86_64.rpm
ejabberdctl live启动正常
