1.切换至root用户
2.uname -a/-m grep MemTotal /proc/meminfo grep SwapTotal /proc/meminfo free -m
3.df -h /tmp 至少1G空间
4.查看安装依赖软件 rpm -q package_name

semmsl, semmns, semopm, and semmni |
# /sbin/sysctl -a | grep sem
This command displays the value of the semaphore parameters in the order listed. |
shmall, shmmax, and shmmni |
# /sbin/sysctl -a | grep shm |
file-max |
# /sbin/sysctl -a | grep file-max |
ip_local_port_range |
# /sbin/sysctl -a | grep ip_local_port_range |

# /sbin/sysctl -a | grep rmem_max |
wmem_default |
# /sbin/sysctl -a | grep wmem_default |
wmem_max |
# /sbin/sysctl -a | grep wmem_max |
不符合要求的,需要按照下面的格式修改/etc/sysctl.conf文件
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
使用下面的命令使修改的内核参数生效# /sbin/sysctl -p
