CentOS6.6體驗_LNMP – Memory of 42

常用命令

#檢查更新
yum check-update
#執行更新
yum update
#安裝軟件，如nano
yum install nano
#查看CentOS版本號
cat /etc/redhat-release
#查看CentOS位數
getconf LONG_BIT
#安裝編譯組件
yum install gcc gcc-c++ make openssl-devel
或者
sudo yum groupinstall 'Development Tools'

首先還是用LNMP練手

參考http://www.krizna.com/centos/install-lemp-on-centos-6/

nginx

去nginx官網下載源碼自己編譯安裝也是極好的，可以參考http://www.runoob.com/linux/nginx-install-setup.html

#用rpm添加nginx官方repository
rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
#檢查更新
yum check-update
#安裝nginx
yum install nginx
#啓動nginx
service nginx start
#添加到開機自動啓動
chkconfig nginx on

nginx默認目錄：
Default document root directory: /usr/share/nginx/html
Default configuration file: /etc/nginx/nginx.conf
Default Virtual host config directory: /etc/nginx/conf.d/
Default Virtual host config file: /etc/nginx/conf.d/default.conf

mysql

yum install mysql mysql-server
service mysqld start
chkconfig mysqld on
#初始化mysql
/usr/bin/mysql_secure_installation

額，默認好像是5.1的，如果想安裝新版本可以從mysql官方源安裝。

rpm -ivh https://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm
#默認5.7，如果要5.6，執行下面兩條命令
yum-config-manager --disable mysql57-community
yum-config-manager --enable mysql56-community
#查看現在庫里的mysql版本
yum repolist enabled | grep mysql
#安裝mysql
yum install mysql-community-server
service mysqld start
mysql_secure_installation
chkconfig mysqld on

新建用戶及數據庫可參考mysql tricks。

安裝默認php5.3

#這裏默認是5.3.3，更高版本請跳過這一節往下看
yum install php-fpm php-mysql
#把php-fpm配置文件中到用戶從apache改爲nginx
nano /etc/php-fpm.d/www.conf
    #修改如下兩行
    user = nginx
    group = nginx
service php-fpm start
chkconfig php-fpm on

添加一個Virtual Host測試下，新建文件/etc/nginx/conf.d/phptest.conf，寫入下面內容，並且重啓nginx使之生效 sudo service nginx reload：

server {
    listen       8080;                          # listen port
    server_name  localhost;                     # Server name
    location / {
        root   /usr/share/nginx/html;           # Document root
        index index.php  index.html index.htm;
    }
    location ~ \.php$ {
        root           /usr/share/nginx/html;   # Document root
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

新建/usr/share/nginx/html/info.php測試下安裝是否成功：

<?php
phpinfo();
?>

升級或安裝php5.5

#rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
nano /etc/yum.repos.d/remi.repo
#修改其中[remi]和[remi-php55]兩部分中的enabled值爲1。
service httpd stop
service mysqld stop
#如果已經安裝了php要升級則執行
yum update -y
#如果是首次安裝則執行下面兩行
sudo yum install mysql-server
sudo yum install php php-mysql
service httpd start
service mysqld start
#更新下mysql
mysql_upgrade -u root -p
#php到配置文件夾/etc/php-fpm.d下會有php.conf.rpmnew，將其命名爲php.conf
#如果使用nginx，要修改user和group值爲nginx

phpmyadmin

yum install phpmyadmin

新建一個文件/etc/nginx/conf.d/phpMyAdmin.conf，內容爲

server {
    listen 8080; 
    location ~ \.php$ {
        root           /usr/share/phpMyAdmin;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
    location / {
        root           /usr/share/phpMyAdmin;
        index          index.php;
    }
}

還有兩點需要注意：

#修改php session到權限爲777
chmod 777 /var/lib/php/session
#mbstring missing
#去掉/etc/php.ini中mbstring前的;
#403

配置網卡相關：

#nano etc/sysconfig/network-scripts/ifcfg-eth0
ONBOOT=yes
NM_CONTROLLED=no
#如果要配置靜態ip
BOOTPROTO=static
    #並增加
IPADDR=192.168.1.42
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=114.114.114.114
DNS2=4.4.4.4
#重啓網絡服務 /etc/init.d/network restart
#修改hostname
#nano /etc/sysconfig/network
HOSTNAME=www.fortytwo.com
    #並在host中增加條目
#nano /etc/hosts
192.168.1.42 www.fortytwo.com
