CentOS 6.6搭建LNMP環境

標籤：

一、安裝前

1、關閉linux的安全機制

vim /etc/selinux/config

SELINUX=enforcing  改為  SELINUX=disabled

 

2、關閉iptables防火牆

   vim /etc/sysconfig/iptables   #把裡邊的條例全部dd刪除掉，wq儲存退出

   service iptables stop            #關閉iptables
   chkconfig iptables off          #開機不自啟動iptables

 

3、配置yum源（本地，網路都可以）#如果能上網的話建議配置網路yum源

詳細如何配置yum請閱讀  http://blog.csdn.net/allen_a/article/details/51198585

 

4、重啟系統

  reboot

 

二、安裝篇

yum list
yum clean all
yum -y install pcre-devel zlib-devel
yum -y install gcc* gcc-*
yum remove httpd
rpm -qa httpd
1）編譯安裝nginx
A.安裝支援軟體
yum -y install pcre-devel zlib-devel
B.建立運行使用者、組
useradd -M -s /sbin/nologin nginx
C.編譯安裝Nginx
tar zxvf nginx-1.6.0
cd nginx-1.6.0
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module
make && make install

/usr/local/nginx/sbin/nginx   # 啟動Nginx

訪問Nginx伺服器的IP,會出現    歡迎來到Nginx

nginx開啟，關閉命令

killall -s HUP nginx
killall -1 nginx

killall -s QUIT nginx
killall -3 nginx


查看日誌資訊
cd /usr/local/nginx/logs/

natstat -anpt | grep nginx


最佳化應用程式控制
vim /etc/init.d/nginx
#!/bin/bash
# chkconfig: - 99 20
# description: Nginx Server Control Script
PROC="/usr/local/nginx/sbin/nginx"
PID="/usr/local/nginx/logs/nginx.pid"
case "$1" in
start)
  $PROC
  $PROG
  ;;
stop)
  kill -s QUIT $(cat $PID)
  ;;
restart)
  $0 stop
  $0 start
  ;;
reload)
  kill -s HUP $(cat $PID)
  ;;
status)
  [ -f $PID ] &> /dev/null
       if [ $? -eq 0 ]
          then 
          netstat  -anpt | grep nginx
       else
          echo "Nginx is not running."
        fi   
  ;;
*)
  echo "Usage: $0 {start|stop|restart|reload|status}"
esac
exit 0 


檢查文法
nginx -t



檢測安裝環境，卸載rpm的應用程式
yum remove httpd mysql php


1、安裝MySQL資料庫
1）編譯安裝MySQL資料庫
yum -y install ncurses-devel


tar zxvf cmake-2.8.6.tar.gz
cd cmake-2.8.6
./configure 
gmake 
gmake install


tar zxvf mysql-5.5.22.tar.gz
cd mysql-5.5.22
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=ALL -DSYSCONFIGDIR=/etc
make && make install


2）最佳化調整
rm -rf /etc/my.cnf
cp support-files/my-medium.cnf /etc/my.cnf
cp support-files/mysql.server /etc/rc.d/init.d/mysqld
chmod +x /etc/rc.d/init.d/mysqld 
chkconfig --level 35 mysqld on
echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
. /etc/profile 或者 source /etc/profile


3）初始化資料庫
groupadd mysql
useradd -M -s /sbin/nologin mysql -g mysql
chown -R mysql:mysql /usr/local/mysql/


/usr/local/mysql/scripts/mysql_install_db  --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --user=mysql


4）啟動資料庫
service mysqld start
mysqladmin -u root password ‘pwd123‘
mysql -u root -p


2、安裝PHP解析環境
1）編譯安裝PHP
yum -y install gd libxml2 libxml2-devel libjpeg-devel libpng-devel
tar zxvf php-5.3.28.tar.gz
cd php-5.3.28 


./configure --prefix=/usr/local/php5/ --with-gd --with-zlib --with-mysql=/usr/local/mysql --with-config-file-path=/usr/local/php5 --enable-mbstring --enable-fpm  --with-jpeg-dir=/usr/lib
make && make install


測試：make test


2）安裝後的調整
cp php.ini-development /usr/local/php5/php.ini
ln -s /usr/local/php5/bin/* /usr/local/bin/
ln -s /usr/local/php5/sbin/* /usr/local/sbin/


3)安裝ZendGuardLoader
tar zxvf ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz
cd ZendGuardLoader-php-5.3-linux-glibc23-x86_64/php-5.3.x/
cp ZendGuardLoader.so /usr/local/php5/lib/php/


vim /usr/local/php5/php.ini
zend_extension=/usr/local/php5/lib/php/ZendGuardLoader.so
zend_loader.enable=1


service nginx restart 


3)配置Nginx支援PHP環境
1）啟動php-fpm進程
cd /usr/local/php5/etc/


cp php-fpm.conf.default php-fpm.conf
useradd -M -s /sbin/nologin php


vim php-fpm.conf
pid = run/php-fpm.pid(去掉分號)
user = php
group = php
pm.start   20    
pm.min     5
pm.max     35
pm.max_children  50


啟動php-fpm進程
/usr/local/sbin/php-fpm 


netstat -apnt | grep php-fpm
netstat -apnt | grep nginx
netstat -apnt | grep mysqld


service nginx restart 或 reload


2）配置Nginx支援PHP解析
location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            #fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi.conf;
        }
3）php頁面的測試訪問
vim t.php
<?php
phpinfo();
?>


vim test.php
<?php 
$link=mysql_connect(‘localhost‘,‘root‘,‘pwd123‘);     //單引號
if($link)
echo "恭喜你，資料庫連接成功！"; 
mysql_close();
?>
