OpevnVZ 一些自用初始化脚本

服务端

准备

系统 centos 6.7

安装 dnsmasq

<source lang=bash> yum install dnsmasq sed -i "s@#resolv-file.*$@resolv-file=/etc/resolv.masqdns" cp /etc/resolv.conf /etc/resolv.masqdns echo "nameserver 127.0.0.1" > /etc/resolv.conf chkconfig dnsmasq on service dnsmasq start </source>

安装 openvz

<source lang=bash> wget -P /etc/yum.repos.d/ http://ftp.openvz.org/openvz.repo rpm --import http://ftp.openvz.org/RPM-GPG-Key-OpenVZ yum install vzkernel cat << "EOF" >> /etc/sysctl.conf

  1. On Hardware Node we generally need
  2. packet forwarding enabled and proxy arp disabled

net.ipv4.ip_forward = 1 net.ipv6.conf.default.forwarding = 1 net.ipv6.conf.all.forwarding = 1 net.ipv4.conf.default.proxy_arp = 0

  1. Enables source route verification

net.ipv4.conf.all.rp_filter = 1

  1. Enables the magic-sysrq key

kernel.sysrq = 1

  1. We do not want all our interfaces to send redirects

net.ipv4.conf.default.send_redirects = 1 net.ipv4.conf.all.send_redirects = 0 EOF

sysctl -p echo "SELINUX=disabled" > /etc/sysconfig/selinux yum install vzctl vzquota ploop reboot </source>

安装 OpenVZ Web Panel

<source lang=bash> gem sources -a http://rubygems.org gem update --system 1.8.25 wget -O - https://raw.githubusercontent.com/sibprogrammer/owp/master/installer/ai.sh | \ bash -s DOWNLOAD_URL=http://owp.softunity.com.ru/download/ovz-web-panel-latest.tgz chkconfig owp on </source> 面板默认登陆用户名密码：admin/admin

注意，安装完毕OpenVZ的内核后，需要重启服务器再安装面板，面板需要将ruby的版本控制在1.8.25。

删除面板的代码: <source lang=bash> wget -O - https://raw.githubusercontent.com/sibprogrammer/owp/master/installer/ai.sh | sh -s UNINSTALL=1 </source>

配置防火墙

iptables -A INPUT -p tcp -m tcp --dport 3000 -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -j MASQUERADE
/etc/init.d/iptables save

vz 配置

vim /etc/sysconfig/vz
mkdir /home/vz
cp -ra /vz/* /home/vz
mv /vz /vz_bak
ln -s /home/vz /

cd
wget http://download.jboss.org/wildfly/8.2.0.Final/wildfly-8.2.0.Final.tar.gz
tar xzvf wildfly-8.2.0.Final.tar.gz
mv wildfly-8.2.0.Final wildfly
rm wildfly-8.2.0.Final.tar.gz
echo 'JAVA_OPTS="$JAVA_OPTS -Djboss.bind.address=0.0.0.0"' >> /home/ubuntu/wildfly/bin/standalone.conf
echo 'JAVA_OPTS="$JAVA_OPTS -Djboss.bind.address.management=0.0.0.0"' >> /home/ubuntu/wildfly/bin/standalone.conf

配置wildfly数据源

cd /home/ubuntu/wildfly/bin
./jboss-cli.sh --connect

创建数据源的命令为：

data-source add --name=core --jndi-name=java:/core --driver-name=postgresql-9.4-1200.jdbc41.jar --connection-url=java:postgresql:core --user-name=postgres --password=postgres --transaction-isolation==TRANSACTION_READ_COMMITTED --min-pool-size=10 --max-pool-size=250
