•            hard    core            unlimited
  

•            soft    nproc           1000000
  

•            hard    nproc           1000000
  

•            soft    nofile          1000000
  

•            hard    nofile          1000000
  

•            soft    memlock         32000
  

•            hard    memlock         32000
  

•            soft    msgqueue        8192000
  

•            hard    msgqueue        8192000
  

2.5 优化内核参数
vim /etc/sysctl.conf
net.ipv4.conf.default.rp_filter = 1
net.ipv4.ip_nonlocal_bind = 1
net.ipv4.ip_forward = 1
# Do not accept source routing
net.ipv4.conf.default.accept_source_route = 0
# Controls the System Request debugging functionality of the kernel
kernel.sysrq = 0
# Controls whether core dumps will append the PID to the core filename.
# Useful for debugging multi-threaded applications.
kernel.core_uses_pid = 1
# Controls the use of TCP syncookies
net.ipv4.tcp_syncookies = 1
# Disable netfilter on bridges.
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-arptables = 0

# Controls the default maxmimum size of a mesage queue
kernel.msgmnb = 65536
# # Controls the maximum size of a message, in bytes
kernel.msgmax = 65536
# Controls the maximum shared segment size, in bytes
kernel.shmmax = 68719476736
# # Controls the maximum number of shared memory segments, in pages
kernel.shmall = 4294967296
# TCP kernel paramater
net.ipv4.tcp_mem = 786432 1048576 1572864
net.ipv4.tcp_rmem = 4096 87380 4194304
net.ipv4.tcp_wmem = 4096 16384 4194304
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_sack = 1
# socket buffer
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.core.netdev_max_backlog = 262144
net.core.somaxconn = 20480
2.6 更改主机名
2.7 所有的服务器做域名和vip绑定
Vim /etc/hosts
192.168.90.248 openstack-vip.preview.local
2.8安装openstack的q版
首先对系统进行初始化：
yum list centos-release-openstack* #查询版本
yum install centos-release-openstack-queens.noarch -y
yum install https://rdoproject.org/repos/rdo-release.rpm
yum install python-openstackclient openstack-selinux -y

3、安装keepalived和haproxy（192.168.90.201和192.168.90.202）
3.1 安装keepalived
yum install keepalived -y
[root@haproxy1 conf]# vim /etc/keepalived/keepalived.conf
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 80
priority 100
advert_int 1
unicast_src_ip 192.168.90.201
unicast_peer {
192.168.90.202
}

authentication {
    auth_type PASS
    auth_pass 123456
}
virtual_ipaddress {
    192.168.90.248 dev eth0 label eth0:0
}

}
[root@linux-host5 ~]# systemctl start keepalived
[root@linux-host5 ~]# systemctl enable keepalived
2.5.3：验证：

注意：192.168.90.203（controller）ping 192.168.90.248是否能ping通，如果ping通ok
如果不通，执行以下操作，然后重启keepalived服务。

3.2安装haproxy
一、 部署haproxy，实现访问6379端口时，轮询访问六个节点
1）下载版本1.8.14版本的harpoxy软件并安装
tar xf haproxy-1.8.14.tar.gz
cd haproxy-1.8.14
make ARCH=x86_64 TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1 USE_CPU_AFFINITY=1 PREFIX=/usr/local/haproxy
make install PREFIX=/usr/local/haproxy
cp haproxy /usr/sbin/
2）配置haproxy相关的参数
[root@master1 init.d]# vim /usr/lib/systemd/system/haproxy.service
[Unit]
Description=HAProxy Load Balancer
After=syslog.target network.target

[Service]
ExecStartPre=/usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -f /etc/haproxy/conf -c -q
ExecStart=/usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -f /etc/haproxy/conf -p /run/haproxy.pid
ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target
[root@master1 init.d]# vim /etc/haproxy/conf/ops.cfg
