3.结果展示
4.错误总结
问题：
[root@server4 html]# /etc/init.d/httpd start
Starting httpd: httpd: apr_sockaddr_info_get() failed for server4.example.com
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
解决方法：
[server1..4]
vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.25.38.1 server1.example.com
172.25.38.2 server2.example.com
172.25.38.3 server3.example.com
172.25.38.4 server4.example.com
问题：
boost::geometry::cs::cartesian>::m_values[1ul]’ may be used uninitialized in this function
解决方法：给大内存和多CPU
问题：
See
make[2]: *** [sql/CMakeFiles/sql.dir/item_geofunc.cc.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [sql/CMakeFiles/sql.dir/all] Error 2
make: *** [all] Error 2
尚未解决，可能是机器真的忙不过来，给大内存和CPU试一试。
