启用内核的包转发功能
修改/etc/sysctl.conf
#net.ipv4.ip_forward = 0
net.ipv4.ip_forward = 1
[root@db1 etc]# sysctl -p //使其马上生效
net.ipv4.ip_forward = 1
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
