新版TeamTalk部署教程
新版TeamTalk部署教程
新版TeamTalk已经在2015年03月28日发布了,目前版本定为1.0.0版本,后续版本号会按照如下规则进行:
1、版本规则按照x.y.z的形式进行。
2、各端小bug修复则版本号中z增加。
3、有新的feature增加,则版本号中y增加。
4、有重大更新及不兼容更新,则版本号x增加。
本教程会在VirtualBox 虚拟机中进行安装部署一整套服务端,并做记录,给大家做个参考,后面会将整个虚拟机打包上传到网盘中,为那些不想自己亲自部署的人一个可用环境。
这篇博客中,不会使用一键部署脚本,我会一步一步手动去部署。另外我会尽量选择源码安装mysql,php,nginx等,后面所有的安装在/usr/local/目录下。(源码安装很多参考了军哥(http://www.lnmp.org)的脚本,在此表示感谢)。
真个部署过程从晚上8:00开始到半夜将近2:00(由于时间太晚了,明天还要上班,所以配置那块后面再写),耗时近6个小时,所以本文也耗时5个多小时才完成,希望可以帮助到大家。
更新:
2015年04月02日更新
更新了配置文件说明
2015年04月07日更新
更新了数据库导入,及问题修复。
2015年05月05日
修复mysql下载不了问题,感谢@Gene反馈。
我的环境如下:
虚拟机:VirtualBox 4.3.18CPU:2核
内存:2GB
硬盘:10GB
操作系统:CentOS 6.5 x64IP:192.168.1.150
下面我们正式开始:
1、更新操作系统
更新操作系统:
CentOS 使用如下命令:
yum update
Ubuntu 使用如下命令:
apt-get update
该命令会执行更新,会消耗一段时间,国内用户,建议使用科大源或者163,搜狐等都可以,这会为大家节省很多时间,具体使用方法,可以见相关的页面:
163源帮助:http://mirrors.163.com/.help/centos.html
:http://mirrors.163.com/.help/ubuntu.html
搜狐源帮助:http://mirrors.sohu.com/help/centos.html
:http://mirrors.sohu.com/help/ubuntu.html
科大源帮助:https://lug.ustc.edu.cn/wiki/mirrors/help/centos
:https://lug.ustc.edu.cn/wiki/mirrors/help/ubuntu
执行上面命令后,会检查一些更新,会出现如下图:
后面会询问是否安装更新,有可能会询问你是否需要导入密钥之类的,输入y即可,如下图所示:
2、删除已经安装的软件
为了减少一些不必要的麻烦,我们需要先卸载系统自带的一些软件,譬如mysql,nginx,php,执行以下命令:
CentOS 执行如下命令:
yum -y remove httpd* php* mysql-server mysql mysql-libs php-mysql
Ubuntu 使用如下命令:
apt-get remove -y apache2 apache2-doc apache2-utils apache2.2-common apache2.2-bin apache2-mpm-prefork apache2-doc apache2-mpm-worker mysql-client mysql-server mysql-common php5 php5-common php5-cgi php5-mysql php5-curl php5-gdkillall apache2dpkg -l |grep mysqldpkg -P libmysqlclient15off libmysqlclient15-dev mysql-commondpkg -l |grep apachedpkg -P apache2 apache2-doc apache2-mpm-prefork apache2-utils apache2.2-commondpkg -l |grep phpdpkg -P php5 php5-common php5-cgi php5-mysql php5-curl php5-gdapt-get purge `dpkg -l | grep php| awk '{print $2}'`
如下图所示:
3、安装必要的依赖软件
由于我选择的是CentOS 最小化安装,所以系统中很多软件是没有安装的,需要我手动安装。
执行如下命令安装一些依赖软件:
CentOS 使用如下命令:
yum -y install wget vim git texinfo patch make cmake gcc gcc-c++ gcc-g77 flex bison file libtool libtool-libs autoconf kernel-devel libjpeg libjpeg-devel libpng libpng-devel libpng10 libpng10-devel gd gd-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glib2 glib2-devel bzip2 bzip2-devel libevent libevent-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel vim-minimal nano fonts-chinese gettext gettext-devel ncurses-devel gmp-devel pspell-devel unzip libcap diffutils
ubuntu 使用如下命令:
apt-get autoremove -yapt-get -fy installapt-get install -y build-essential gcc g++ makeapt-get install -y --force-yes wget vim git texinfo patch build-essential gcc g++ make cmake automake autoconf re2c wget cron bzip2 libzip-dev libc6-dev file rcconf flex vim nano bison m4 gawk less make cpp binutils diffutils unzip tar bzip2 libbz2-dev unrar p7zip libncurses5-dev libncurses5 libncurses5-dev libncurses5-dev libtool libevent-dev libpcre3 libpcre3-dev libpcrecpp0 libssl-dev zlibc openssl libsasl2-dev libltdl3-dev libltdl-dev libmcrypt-dev zlib1g zlib1g-dev libbz2-1.0 libbz2-dev libglib2.0-0 libglib2.0-dev libpng3 libjpeg62 libjpeg62-dev libjpeg-dev libpng-dev libpng12-0 libpng12-dev curl libcurl3 libmhash2 libmhash-dev libpq-dev libpq5 gettext libncurses5-dev libcurl4-gnutls-dev libjpeg-dev libpng12-dev libxml2-dev zlib1g-dev libfreetype6 libfreetype6-dev libssl-dev libcurl3 libcurl4-openssl-dev libcurl4-gnutls-dev mcrypt libcap-dev diffutils ca-certificates debian-keyring debian-archive-keyring;apt-get -fy installapt-get -y autoremove
过程如下图所示:
如下图安装结束:
4、安装mysql
本次安装的mysql版本是5.6.选择从搜狐源下载,编译过程漫长。
4.1 下载
wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.23.tar.gz
4.2 解压编译
执行如下命令:
tar -zxvf mysql-5.6.23.tar.gzcd mysql-5.6.23cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_READLINE=1 -DWITH_SSL=system -DWITH_ZLIB=system -DWITH_EMBEDDED_SERVER=1 -DENABLED_LOCAL_INFILE=1make -j 2 && make install
编译将是一个漫长得过程。。。不同的机器性能等待时间不同。
make的-j参数可以使make进行并行编译编译。我cpu的个数是2,所以指定为2.
4.3 添加mysql用户
groupadd mysqluseradd -s /sbin/nologin -M -g mysql mysql
4.4 修改配置文件
vim /etc/my.cnf
下面给出一份参考配置(只是测试用,如果要用于生产环境,请自行调配):

如果看到如下图,恭喜你,启动成功:
8 升级gcc,gdb等(非常漫长,如果系统中自带的g++支持C++11,可跳过此步骤)
8.1 下载gcc4.9.2
使用日本的源可能会快些:
wget http://ftp.tsukuba.wide.ad.jp/software/gcc/releases/gcc-4.9.2/gcc-4.9.2.tar.gz
8.2 解压编译gcc4.9.2
tar -zxvf gcc-4.9.2.tar.gzcd gcc-4.9.2./contrib/download_prerequisitesmkdir gcc-build-4.9.2cd gcc-build-4.9.2../configure --prefix=/usr -enable-checking=release -enable-languages=c,c++ -disable-multilibmake -j 2 && make installcd ../../
8.3 下载termcap
wget ftp://ftp.gnu.org/gnu/termcap/termcap-1.3.1.tar.gz
8.4 解压编译termcap
tar -zxvf termcap-1.3.1.tar.gzcd termcap-1.3.1./configure --prefix=/usrmake -j 2 && make install
8.5 下载gdb
wget http://ftp.gnu.org/gnu/gdb/gdb-7.9.tar.gz
8.6 解压编译gdb
tar -zxvf gdb-7.9.tar.gzcd gdb-7.9./configure --prefix=/usrmake -j 2 && make install
9 重启电脑
shutdown -r now
10 安装PB
10.1 下载pb
wget https://github.com/google/protobuf/releases/download/v2.6.1/protobuf-2.6.1.tar.gz
10.2 解压编译pb
tar -zxvf protobuf-2.6.1cd protobuf-2.6.1./configure --prefix=/usr/local/protobufmake -j 2 && make install
11 下载TeamTalk代码
git clone https://github.com/mogujie/TeamTalk.git
12 生成pb文件
12.1 拷贝pb相关文件
拷贝pb的库、头文件到TeamTalk相关目录中:
mkdir -p /root/TeamTalk/server/src/base/pb/lib/linux/
cp /usr/local/protobuf/lib/libprotobuf-lite.a /root/TeamTalk/server/src/base/pb/lib/linux/
cp -r /usr/local/protobuf/include/* /root/TeamTalk/server/src/base/pb/
12.2 生成pb协议
cd /root/TeamTalk/pb
执行:
export PATH=$PATH:/usr/local/protobuf/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/protobuf/lib
sh create.sh
生成协议相关源码文件。
再执行:
sh sync.sh
将相关文件拷贝到server 目录下。
13 安装依赖
cd /root/TeamTalk/server/src
sh make_log4cxx.sh
sh make_hiredis.sh
14 编译server
14.1 编译
由于我们是源码安装mysql的,所以对db_proxy_server中的CMakeList做一定的修改.
原来:
SET(MYSQL_INCLUDE_DIR /usr/include/mysql)
SET(MYSQL_LIB /usr/lib64/mysql)
修改为:
SET(MYSQL_INCLUDE_DIR /usr/local/mysql/include)
SET(MYSQL_LIB /usr/local/mysql/lib)
进入server目录下,执行:
sh build.sh version 1.0.0
如果一切顺利,你将会看到如下画面:
15 配置server(时间太晚了,明天再来写吧)
配置就以本机192.168.1.150 为例。
15.1 配置文件说明:
15.1.1 login_server
ClientListenIP=0.0.0.0 # can use multiple ip, seperate by ';'ClientPort=8008HttpListenIP=0.0.0.0HttpPort=8080MsgServerListenIP=0.0.0.0 # can use multiple ip, seperate by ';'MsgServerPort=8100msfs=http://127.0.0.1:8700/discovery=http://127.0.0.1/api/discovery
ClientListenIP:目前已经作废。
ClientPort:与上一个配套,同样作废。
HttpListenIP:供客户端过来获取msg_server及其他参数的接口地址,走http协议。
HttpPort:与上一个配套使用。
MsgServerListenIP:用于监听msg_server上报信息使用。
MsgServerPort:与上一个配套使用。msg_server启动的时候回来连接该ip:port,以上报自己的信息。
在运行过程中,也会实时将自己的信息汇报给login_server。
msfs:小文件存储的地址,该配置是提供给客户端获取参数时使用。
discovery:发现内容获取地址,该配置是提供给客户端获取参数时使用。
参考配置:
ClientListenIP=192.168.1.150ClientPort=8008HttpListenIP=192.168.1.150HttpPort=8080MsgServerListenIP=192.168.1.150MsgServerPort=8100msfs=http://192.168.1.150:8700/discovery=http://192.168.1.150/api/discovery
15.1.2 route_server
ListenIP=0.0.0.0 # Listening IP
ListenMsgPort=8200 # Listening Port for MsgServer
route_server配置比较简单,一个监听ip,一个监听port就OK了,供msg_server连接上来用。
参考配置:
ListenIP=192.168.1.150ListenMsgPort=8200
15.1.3 http_msg_server
ListenIP=0.0.0.0
ListenPort=8400

DBServerPort2=10600
RouteServerIP1=localhost
RouteServerPort1=8200
#RouteServerIP2=localhost#RouteServerPort2=8201
ListenIP:监听IP,供其他人来调用http_msg_server接口,比如,php在创建群组的时候,就会来调用http_msg_server的接口。
ListenPort:监听端口,与上一个配套使用。
ConcurrentDBConnCnt:DB数目,目前必须配置为2的整数倍,是历史遗留问题,后期会修复。
DBServerIP(x):db_proxy_server监听的IP,http_msg_server会主动去连接。
DBServerPort(x):db_proxy_server监听的Port
RouteServerIP(x):route_server监听的IP,http_msg_server会主动去连接。
RouteServer(x):route_server监听的Port

ListenIP:监听客户端连接上来的IP。
ListenPort:与上一个配套使用,监听客户端连接的port。
ConcurrentDBConnCnt:db_proxy_server个数,同http_msg_server 一样。
DBServerIP(x):db_proxy_server监听的ip,msg_server主动去连接。
DBServerPort(x):db_proxy_server监听的port。
LoginServerIP(x):login_server监听的ip,msg_server会主动去连接,汇报本机信息。
LoginServerPort(x):login_server监听的port。
RouteServerIP(x):route_server监听的IP,msg_server主动去连接。
RouteServerPort(x):route_server监听的port。
PushServerIP(x):push_server监听的IP,msg_server会主动去连接,给ios系统推送消息。
PushServerPort(x):push_server监听的port。
FileServerIP(x):file_server监听的IP,msg_server会主动去连接,用于文件传输,暂时未用到。
FileServerPort(x):file_server监听的port。
IpAddr1:msg_server监听的ip,用于汇报给login_server,便于login_server在客户端请求的时候返回给客户端。注意,这个ip一定要是客户端能连接的ip,之前发现好多人配置成127.0.0.1,这是不行的。
IpAddr2:同上。
aesKey:消息文本加密密钥.这里配置主要在msg_server向push_server推送的时候需要将加密的消息进行解密。
参考配置:

16、更新
16.1 导入mysql
登陆mysql:
mysql -uroot -p
输入密码:test123.
创建TeamTalk数据库:
create database teamtalk
见到如下:
mysql> create database teamtalk;
Query OK, 1 row affected (0.00 sec)
创建成功。
创建teamtalk用户并给teamtalk用户授权teamtalk的操作:
grant select,insert,update,delete on teamtalk.* to 'teamtalk'@'%' identified by 'test@123';
flush privileges;
导入数据库.
use teamtalk;
source /root/TeamTalk/auto_setup/mariadb/conf/ttopen.sql;
show tables;
如下:
mysql> show tables;+--------------------+| Tables_in_teamtalk |+--------------------+| IMAdmin || IMAudio || IMDepart || IMDiscovery || IMGroup || IMGroupMember || IMGroupMessage_0 || IMGroupMessage_1 || IMGroupMessage_2 || IMGroupMessage_3 || IMGroupMessage_4 || IMGroupMessage_5 || IMGroupMessage_6 || IMGroupMessage_7 || IMMessage_0 || IMMessage_1 || IMMessage_2 || IMMessage_3 || IMMessage_4 || IMMessage_5 || IMMessage_6 || IMMessage_7 || IMRecentSession || IMRelationShip || IMUser |+--------------------+25 rows in set (0.00 sec)mysql>
16.2 修改php
执行如下命令:
cd /home/wwwroot/defaultcp -r /root/TeamTalk/php/* /home/wwwroot/default
修改config.php:
vim application/config/config.php
修改第18-19行:
$config['msfs_url'] = 'http://192.168.1.150:8700/';
$config['http_url'] = 'http://192.168.1.150:8400';
修改database.php
vim application/config/database.php
修改52-54行:
$db['default']['hostname'] = '192.168.1.150';
$db['default']['username'] = 'tamtalk';
$db['default']['password'] = 'test@123';
$db['default']['database'] = 'teamtalk';
访问后,看到如下图:
16.3 修改nginx.conf
之前给出的配置有点问题,新配置如下:

}
17、测试
在后台添加test用户,运行ios 模拟器,登陆看到如下图
18、virtualBox 环境
置于怎么加载虚拟机,怎么运行虚拟机请自行百度,谷歌。
18.1 我虚拟机的环境
链接: http://pan.baidu.com/s/1sjx8g49 密码: 4572
18.2 虚拟机硬盘
因网盘大小限制1G,所以将虚拟机硬盘切分成3个文件上传:
链接: http://pan.baidu.com/s/1mgDXvwW 密码: tgzp
请使用如下命令合并解压:
cat CentOS-hd.tar.gz.* > CentOS-hd.tar.gz
tar -zxvf CentOS-hd.tar.gz
18.3 账号信息
虚拟机账号信息如下:
linux账号密码:root/123456
mysql root账号密码:root/test123
mysql teamtalk账号密码:teamtalk/test@123
php 后台账号密码:admin/admin
测试用户账号密码:test/test
18.4 运行
启动虚拟机后,运行如下命令:
ps -ef|grep server
如果看到如下:
[root@zhyh ~]# ps -ef|grep server
root 1653 1 0 22:13 ? 00:00:05 /usr/local/redis/bin/redis-server *:6379root 1658 1 1 22:13 ? 00:00:21 ./db_proxy_server
root 1717 1 0 22:13 ? 00:00:02 ./http_msg_server
root 1729 1 0 22:13 ? 00:00:02 ./route_server
root 1737 1 0 22:14 ? 00:00:02 ./login_server
root 1757 1 0 22:15 ? 00:00:02 ./msg_server
root 1788 1774 0 22:34 pts/2 00:00:00 grep server
如果没有发现:db_proxy_server, http_msg_server,route_server,login_server,msg_server的进程,请执行如下命令启动:
cd /usr/local/teamtalk
cd xxxx
../daeml xxxx
xxx代表相应的程序名。通过查看:xxxx/log/default.log 查看程序错误。
18.5 redis,php,nginx,mysql的启动,停止与重启
/etc/init.d/redis {start|stop|restart}
/etc/init.d/php-fpm {start|stop|force-quit|restart|reload}
/etc/init.d/nginx {start|stop|force-quit|restart|reload|status|configtest}
/etc/init.d/mysql {start|stop|restart|reload|force-reload|status} [ MySQL server options ]
