Centos6.3服務器環境的搭建

 服務器環境的安裝簡略的步驟;備忘。可以寫一個腳本，這對安裝多臺服務器是非常有必要的。省時省力。

1、更新epel源

#rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm
#rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
#yum install yum-priorities
#yum update
#yum upgrade

 

2、關閉selinux

修改/etc/selinux/config

將SELINUX=enforcing修改爲SELINUX=disabled

#setenforce 0

 

 

3、修改ssh配置

修改/etc/ssh/sshd_config

禁用root用戶登錄： #PermitRootLogin yes修改爲PermitRootLogin no

加快ssh登錄：#UseDNS yes 修改爲UseDNS no

重啓：service sshd restart

iptables 2233端口開啓

#service iptables restart

 

 

4、修改系統時間

#yum -y install ntp
#ntpdate ntp.fudan.edu.cn
#cp -f /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

 

5、基礎服務

#yum install wget gcc gcc-c++ make openssl-devel openssh-clients

 

Nginx一般是配置了2個附加模塊的：pcre和ngx_cache_purge，前者用來支持正則表達式解析，後者用來支持緩存動態請求。pcre需要先安裝

 

6、安裝pcre

 

#wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.31.tar.gz
#tar -zxvf pcre-8.31.tar.gz
#cd pcre-8.31
#./configure --prefix=/usr/local/pcre-8.31
#make && make install

 

 

7、安裝cache_purge

 

#wget http://labs.frickle.com/files/ngx_cache_purge-1.6.tar.gz
#tar -zxvf ngx_cache_purge-1.6.tar.gz

8、nginx安裝

使用 /usr/local/nginx/sbin/nginx -V 可以查看配置參數，這點在基於一個已有nginx給另外一臺服務器安裝是很有用的。

 

#groupadd nginx
#useradd -g nginx nginx
#wget http://nginx.org/download/nginx-1.2.4.tar.gz
#tar -zxvf nginx-1.2.4.tar.gz
#cd nginx-1.2.4
#./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-pcre=pcre解壓的目錄路徑 --with-http_ssl_module --add-module=前面第七步解壓的路徑
#make && make install
#/usr/local/nginx/sbin/nginx

增加啓動腳本然後開啓iptables 80端口

 

vi /etc/sysconfig/iptables 增加
#-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
重啓服務
#service iptables restart

 

9、安裝php-fpm、mysql等

 

#rpm --import http://rpms.famillecollet.com/RPM-GPG-KEY-remi
#yum install yum-priorities
#vi /etc/yum.repos.d/ remi.repo

插入下面內容

 

[remi]
name=Les RPM de remi pour Enterprise Linux $releasever - $basearch
#baseurl=http://rpms.famillecollet.com/enterprise/$releasever/remi/$basearch/
mirrorlist=http://rpms.famillecollet.com/enterprise/$releasever/remi/mirror
enabled=1
priority=10
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
failovermethod=priority

保存，然後

#yum install php mysql mysql-server php-mysql php-gd php-xml php-mbstring php-ldap php-pear php-mcrypt php-xmlrpc php-devel mysql-connector-odbc mysql-devel libdbi-dbd-mysql

#chkconfig nginx on
#chkconfig mysqld on
#chkconfig php-fpm on
#service nginx start
#service mysqld start

設置mysql root密碼

 

# mysql
> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456')

 

 

10、安裝jdk7+tomcat7

11、安裝snmp

 

#yum install -y net-snmp net-snmp-utils
配置就不詳細列出了
#chkconfig snmpd on
#service snmpd restart

 

12、添加數據庫備份腳本

/data/backup/mysql_backup.sh

 

#!/bin/bash
#功能說明：本功能用於備份整個數據庫

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin
export PATH

dbuser='root'
dbpasswd='123456'

#time
backtime=`date +%Y%m%d%H%M%S`
#log path
logpath='/data/backup/all/'
#datapath
datapath='/data/backup/all/'

echo ‘"備份時間爲${backtime} 開始" >> ${logpath}/mysqllog.log

source=`mysqldump -u ${dbuser} -p${dbpasswd} --all-databases > ${logpath}/${backtime}.sql` 2>> ${logpath}/mysqllog.log;

if [ "$?" == 0 ];then
    cd $datapath
    tar jcf ${backtime}.tar.bz2 ${backtime}.sql > /dev/null
    rm -f ${datapath}/${backtime}.sql

    echo "數據庫表 ${dbname} 備份成功!!" >> ${logpath}/mysqllog.log
else
    echo "數據庫表 ${dbname} 備份失敗!!" >> ${logpath}/mysqllog.log
fi

 

#!/bin/bash
#用於備份單個或幾個數據庫
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin
export PATH

dbuser='root'

dbpasswd='123456'

dbname='mysql'

backtime=`date +%Y%m%d%H%M%S`

logpath='/data/backup/one/'

datapath='/data/backup/one/'

echo ‘"備份時間爲${backtime},備份數據庫表 ${dbname} 開始" >> ${logpath}/mysqllog.log

for table in $dbname; do
source=`mysqldump -u ${dbuser} -p${dbpasswd} ${table}> ${logpath}/${backtime}.sql` 2>> ${logpath}/mysqllog.log;

if [ "$?" == 0 ];then
    cd $datapath

    tar jcf ${table}${backtime}.tar.bz2 ${backtime}.sql > /dev/null

    rm -f ${datapath}/${backtime}.sql

    echo "數據庫表 ${dbname} 備份成功!!" >> ${logpath}/mysqllog.log
else

    echo "數據庫表 ${dbname} 備份失敗!!" >> ${logpath}/mysqllog.log
fi

done

 

13、nginx日誌分割腳本

 

#!/bin/bash
# This script run at 00:00

# The Nginx logs path
logs_path="/var/log/nginx/"
time_dir=$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")
fulltime=$(date -d "yesterday" +"%Y%m%d")

declare -a items
items[0]=nginxstatus
items[1]=access
items[2]=error

for item in ${items[@]}
  do
  mkdir -p ${logs_path}${item}/${time_dir}/
  mv ${logs_path}${item}.log ${logs_path}${item}/${time_dir}/${item}_${fulltime}.log
done
