目标

为四台新服务器部署MySQL、Coreseek、Redis、MongoDB、NFS、Varnish等服务。四台服务器分为两组、使用Linux-HA + Pacemaker 实现高可用（HA, High-Availablility）。

生产服务器基于安全原因考虑不会安装gcc等编译工具，因此所有软件的编译工作都在专门的编译机上完成。编译完成后再部署到生产环境，依赖用yum、rpm解决。

硬件环境

Linux-HA  3.0

Pacemaker

Pacemaker = CRM = Cluster Resource Manager，

通过yum安装

yum install cluster-glue resource-agents pacemaker

编译glue

./autogen.sh
./configure --prefix=/opt/servers
make
make install

./configure 的输出

注意 Use system LTDL， 在未安装lib tool-ltdl-devel之前该项会显示为no，且编译会报错

另外一个可能遇到的错误是关于uuid的，简单的yum install libuuid-devel可以解决，在解决这个问题的时候我google了一下，如果不行可能还会需要在configure的时候带上参数 LIBS=’/lib/libuuid.so.1’（注意，如果是64位则是/lib64/….）。

编译Heartbeat 3

./bootstrap
LIBS="/lib64/libuuid.so.1" CFLAGS="-I/opt/servers/include -L/opt/servers/lib" ./configure --prefix=/opt/servers
make
make install

因为我们的安装路径非标准路径，所以这里要指定一下CFLAGS 的include path，否则configure会因找不到glue_config.h而报错

checking for heartbeat/glue_config.h... no
configure: error: in `/root/build/Heartbeat-3-0-7e3a82377fa8':
configure: error: Core development headers were not found
See `config.log' for more details.

虽然已经在ldconfig 里加上了/opt/servers/lib 但是如果不在CFLAGS里指定 lib path 还是会导致 ld 找不到 -lplumb （/opt/servers/lib/libplumb.so）。
另外如果没有安装libxslt-devel在make的时候还会导致 “gmake[1]: –xinclude: Command not found”。

./configure 输出

到这里 cluster-glue 和 heartbeat 都编译完成了。

然后老大说要用rpm装。。。我了个去。。。

然后centos 6.2的源里 cluster-glue、resource-agents、pacemaker 都有，就是没有heartbeat。 幸好heartbeat的source里提供了.spec 可以用rpmbuild来生成rpm包。

下面继续 heartbeat.rpm 的 build过程

首先把下载下来的heartbeat源码包解压一份，然后再把源码包(.tar.gz)复制到 /root/rpmbuild/SOURCES/heartbeat.tar.bz2

tar -jxf Heartbeat-3.0.5.tar.bz2
cp Heartbeat-3.0.5.tar.bz2 /root/rpmbuild/SOURCES/heartbeat.tar.bz2
cd Heartbeat-XXXXXX
# 解决依赖
yum install ncurses-devel openssl-devel gettext bison flex mailx cluster-glue-libs-devel docbook-dtds docbook-style-xsl
# 开始生成。 （-bb 只编译二进制rpm包 -bs 只编译源码rpm包 -ba 同时编译二进制和源码rpm包）
rpmbuild -ba heartbeat-fedora.spec

最后生成文件

未完未完。。。
中途被拉去解决别的问题，HA的部署工作被人接手掉了
