OpevnVZ 一些自用初始化脚本

服务端

准备

系统 centos 6.7

安装 dnsmasq

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

安装 openvz

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
# On Hardware Node we generally need
# 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

# Enables source route verification
net.ipv4.conf.all.rp_filter = 1

# Enables the magic-sysrq key
kernel.sysrq = 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

安装 OpenVZ Web Panel

gem sources -a http://rubygems.org
gem update --system 1.8.25
wget -O - https://raw.githubusercontent.com/sibprogrammer/owp/master/installer/ai.sh | \
sh -s DOWNLOAD_URL=http://owp.softunity.com.ru/download/ovz-web-panel-latest.tgz
chkconfig owp on

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:

wget -O - https://raw.githubusercontent.com/sibprogrammer/owp/master/installer/ai.sh | sh -s UNINSTALL=1

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 /

客户机

sed -i "s/archive.ubuntu.com/mirrors.163.com/" /etc/apt/sources.list
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 40976EAF437D05B5
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 3B4FE6ACC0B21F32
apt-get update
apt-get dist-upgrade
locale-gen --lang zh_CN.UTF-8
dpkg-reconfigure locales

echo "Asia/Shanghai" >/etc/timezone
apt-get install openjdk-7-jdk
apt-get install sudo screen
adduser ubuntu
adduser ubuntu sudo

安装数据库 postgresql

apt-get install postgresql postgresql-contrib
sed -i "s/#\(include_if_exists.*\)/\1/" /etc/postgresql/9.3/main/postgresql.conf
echo "listen_addresses = '*'" >> /etc/postgresql/9.3/main/exists.conf
echo "host    all             all             0.0.0.0/0            md5" >> /etc/postgresql/9.3/main/pg_hba.conf
/etc/init.d/postgresql restart

设置数据库密码

sudo -u postgres psql postgres
postgres=# \password postgres
postgres=# \quit

安装 uuid 扩展

sudo -u postgres psql postgres
postgres=# CREATE EXTENSION "uuid-ossp";
CREATE EXTENSION
postgres=# select uuid_generate_v4(); 
          uuid_generate_v4           
--------------------------------------

下载wildfly

su ubuntu
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
echo 'ubuntu=35291eedea6d270cb71fe7dfd36d0c89' >> /home/ubuntu/wildfly/standalone/configuration/mgmt-users.properties
echo 'ubuntu=' >> /home/ubuntu/wildfly/standalone/configuration/mgmt-groups.properties
cd /home/ubuntu/wildfly/standalone/deployments
wget https://jdbc.postgresql.org/download/postgresql-9.4-1200.jdbc41.jar

建立数据库

sudo -u postgres createdb core -E UTF8 -T template0

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

例如：

[standalone@localhost:9990 /] 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
[standalone@localhost:9990 /] exit
