FMS（Flash Media Server）共享內存問題解決
1）FMS報錯信息
Apr 16 10:21:56 LSCRtest2 Server[21642]: Process (21642) : shared memory (__FCS__serverstats_) init failed.
Apr 16 10:22:01 LSCRtest2 Server[21662]: Process (21662) : shared memory (__FCS__serverstats_) init failed.
2）據查是shm共享內存問題 3）查看共享內存情況
當時機器的共享內存設置情況為
[root@LSCRtest2 setup]# sysctl -a|grep kernel.shm
kernel.shmmni = 4096
kernel.shmall = 0
kernel.shmmax = 0
共享內存情況是
[root@LSCRtest2 setup]#? ipcs ------ Shared Memory Segments --------
key??????? shmid????? owner????? perms????? bytes????? nattch???? status????? ------ Semaphore Arrays --------
key??????? semid????? owner????? perms????? nsems????
0x00000000 163840???? apache??? 600??????? 1????????
0x00000000 196609???? apache??? 600??????? 1????????
0x00000000 229378???? apache??? 600??????? 1???????? ------ Message Queues --------
key??????? msqid????? owner????? perms????? used-bytes?? messages??? 4）正常運行FMS的機器 共享內存的內核設置情況
[root@LSCRtest2 setup]# sysctl -a|grep kernel.shm
kernel.shmmni = 4096
kernel.shmall = 2097152
kernel.shmmax = 33554432
key??????? msqid????? owner????? perms????? used-bytes?? messages?
[root@LSCRtest2 setup]# ipcs ------ Shared Memory Segments --------
key??????? shmid????? owner????? perms????? bytes????? nattch???? status?????

0x450f0dda 524299???? root????? 666??????? 1???????? ------ Message Queues --------
5）更改/etc/sysctl.conf文件里面填加
kernel.shmall = 2097152
kernel.shmmax = 33554432
完成后sysctl -p生效，重啟fms 正常 開始看到http://forums.adobe.com/thread/416673這文章介紹的解決方法時走了一個彎路，以為是sysctl里面的mem相關的設置選項，呵呵，對共享內存不了解，看完另一篇文章的介紹時，我曾照他方法在/dev/shm下建了一個tmp目錄給了1777權限鏈接到fms目錄的tmp目錄里，發現沒有反應，最后查找關于shared memory? failed 相關內容找到一篇有關于啟動一個服務啟動問題即共享內存問題，于是找到了解決的辦法。

總結
