标题: BSS3.0计费安装部署手册
1.1.1 硬件要求云化主机资源需要较多,大致规划如下
l Oracle数据库2台,用于配置和生产数据,需要较高配置
l DDAL和Nats消息系统18台,
l 余额服务12台,需要大内存
l 累积量服务12台,需要大存储
具体配置要求见主机需求excel!
1.1.2 系统要求Red Hat Enterprise LinuxServer release 7.0(Santiago)或者以上
1.1.3 参数要求系统参数ulimit按照如下要求设置
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 514978
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 102400
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 65536
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
ulimit参数:
-S use the `soft' resource limit
-H use the `hard' resource limit
-a all current limits are reported
-b the socket buffer size
-c the maximum size of core files created
-d the maximum size of a process's data segment
-e the maximum scheduling priority (`nice')
-f the maximum size of files written by the shell and its children
-i the maximum number of pending signals
-l the maximum size a process may lock into memory
-m the maximum resident set size
-n the maximum number of open file descriptors
-p the pipe buffer size
-q the maximum number of bytes in POSIX message queues
-r the maximum real-time scheduling priority
-s the maximum stack size
-t the maximum amount of cpu time in seconds
-u the maximum number of user processes
-v the size of virtual memory
-x the maximum number of file locks
内核参数按照如下设置
#每个消息队列的最大字节限制
kernel.msgmnb = 2147483647
#每个消息的最大size.
kernel.msgmax = 2147483647
#内核参数定义单个共享内存段的最大值
kernel.shmmax = 68719476736
#参数是控制共享内存页数
kernel.shmall = 4294967296
kernel.unknown_nmi_panic = 1
#这个参数决定了系统中同时运行的最大的message queue的个数
kernel.msgmni = 60000
kernel.sem = 10000 32000 100 256
#SEMMSL 10000 表示每个信号集中的最大信号量数目
#SEMMNS 32000 表示系统范围内的最大信号量总数目
#SEMOPM 100 表示每个信号发生时的最大系统操作数目
#SEMMNI 256 表示系统范围内的最大信号集总数目
修改方式:root用户修改
1) 修改/etc/sysctl.conf
2) 重新加载sysctl-p /etc/sysctl.conf
3) 查看内核参数ipcs –l
