Ubuntu 14.04服务器安装及软件配置
1、安装操作系统，配置root账号，通过sudo设置root的密码 如果使用ubuntu server 14.04，开启root需额外配置
1.开启root远程登录权限
sudo vi /etc/ssh/sshd_config
将PermitRootLogin without-password 修改为PermitRootLogin yes
2.重启ssh服务
service ssh restart
2、更新sources.list，然后 apt-get update
vim /etc/apt/sources.list
deb http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse deb http://mirrors.sohu.com/ubuntu/ trusty main restricted universe multiverse deb http://mirrors.sohu.com/ubuntu/ trusty-security main restricted universe multiverse deb http://mirrors.sohu.com/ubuntu/ trusty-updates main restricted universe multiverse deb http://mirrors.sohu.com/ubuntu/ trusty-proposed main restricted universe multiverse deb http://mirrors.sohu.com/ubuntu/ trusty-backports main restricted universe multiverse deb-src http://mirrors.sohu.com/ubuntu/ trusty main restricted universe multiverse deb-src http://mirrors.sohu.com/ubuntu/ trusty-security main restricted universe multiverse deb-src http://mirrors.sohu.com/ubuntu/ trusty-updates main restricted universe multiverse deb-src http://mirrors.sohu.com/ubuntu/ trusty-proposed main restricted universe multiverse deb-src http://mirrors.sohu.com/ubuntu/ trusty-backports main restricted universe multiverse
apt-get update
3、通过 locale -a ，检查中文包问题，（ 具体参考：英文Ubuntu安装中文包（locale）的方法；），然后，在/root/.profile 中增加： export LC_ALL=zh_CN.UTF-8（ 具体参考： 调整更改ubuntu时区,时间,locale ）。
vim /root/.profile
export LC_ALL=zh_CN.UTF-8
输入以下命令安装：
cd /usr/share/locales
sudo ./install-language-pack zh_CN
然后重开终端，就可以发现中文locale已经安装完毕，警告已经不再出现了。
当然，还可以执行：
sudo locale-gen
重建locale。
Ubuntu 内存问题：调整参数：/etc/sysctl.conf 【针对4G内存进行配置，老柏优化】
vim /etc/sysctl.conf
vm.lowmem_reserve_ratio = 256 32 32 vm.min_free_kbytes = 307200
4、安装相关软件
安装openjdk
sudo apt-get install openjdk-7-jdk
安装MySQL
sudo apt-get install mysql-server
安装libcv
sudo apt-get install libcv2.4
安装tomcat7
sudo apt-get install tomcat7 tomcat7-admin
安装gcc
apt-get install build-essential
安装libstdc++5
sudo apt-get install libstdc++5
安装libxv-dev
apt-get install libxv-dev
安装libcurl (httpclient)
./configure --prefix=/usr/local/curl ; make ; make install
5、软件与环境参数配置
环境变量：
vim /root/.profile
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/opt/xdt/videocheck/libs/dh:/opt/xdt/videocheck/libs/hk export JAVA_OPTS="-server -Xms512m -Xmx1024m -XX:PermSize=600M -XX:MaxPermSize=600m" export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/opt/xdt/videocheck/libs/dh:/opt/xdt/videocheck/libs/hk export LC_ALL=zh_CN.UTF-8 export JAVA_OPTS="-server -Xms512m -Xmx1024m -XX:PermSize=600M -XX:MaxPermSize=600m"
6、优化tomcat
安装authbind工具： apt-get install authbind
修改tomcat配置文件： /etc/default/tomcat7
/etc/default/tomcat7， 修改：AUTHBIND=yes
开放80端口：
touch /etc/authbind/byport/80
chmod 0755 /etc/authbind/byport/80
chown tomcat7:tomcat7 /etc/authbind/byport/80
7、MySQL数据库（存储过程与参数配置）
开启MySQL Event统计功能：
sudo vim /etc/mysql/my.cnf
增加下面内容：
— 查看是否开启定时器
SHOW VARIABLES LIKE \’event_scheduler\’;
— 开启定时器 0：off 1：on
SET GLOBAL event_scheduler = 1;
event_scheduler = 1
bind-address = 0.0.0.0
[client]
default-character-set=utf8
[mysqld]
character_set_server=utf8
[mysql]
default-character-set=utf8
GRANT ALL PRIVILEGES ON *.* TO \’root\’@\’%\’ IDENTIFIED BY \’system\’ WITH GRANT OPTION;
flush privileges;
啦啦啦
