修改主配置文件
添加access日志及虚拟主机目录
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                       '$status $body_bytes_sent "$http_referer" '
                       '"$http_user_agent" "$http_x_forwarded_for"';

#nginx vhosts config
    include extra/www.conf;
    include extra/bbs.conf;
    include extra/blog.conf;


创建存放虚拟主机的目录
[iyunv@web02 conf]# mkdir extra
[iyunv@web02 extra]# touch www.conf
[iyunv@web02 extra]# touch bbs.conf
[iyunv@web02 extra]# touch blog.conf
修改每个虚拟主机的conf目录
   server {
        listen       80;
        server_name  www.etiantian.org etiantian.org;
        location / {
            root   html/www;
            index  index.html index.htm;

yum install freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libxslt-devel -y
rpm -qa zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
需要先安装支持的软件包
cd /home/oldboy/tools
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar zxf libiconv-1.14.tar.gz
cd libiconv-1.14
./configure --prefix=/usr/local/libiconv
make
make install
cd ../

2、PHP相关扩展库
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
yum -y install libmcrypt-devel
yum -y install mhash
yum -y install mcrypt
rpm -qa libmcrypt-devel mhash mcrypt

解压php安装包，编辑

搭建blog命令
mysql -uroot -poldboy123
create database wordpress;
show databases;
grant all on wordpress.* to wordpress@'localhost' identified by '123456';
select user,host from mysql.user;
show grants for wordpress@'localhost';
flush privileges;

下载博客安装
wget https://cn.wordpress.org/wordpress-4.5.1-zh_CN.tar.gz
  ll
tar xf wordpress-4.5.1-zh_CN.tar.gz
ls wordpress
cp -a wordpress/* /application/nginx/html/blog/
ls /application/nginx/html/blog/
chown -R www.www /application/nginx/html/blog/
ls /application/nginx/html/blog/
ls /application/nginx/html/blog/ -l
history


分离命令
wed命令
mysqldump -uroot -poldboy123 wordpress -B |gzip>bak.sql.gz
scp bak.sql.gz  root@10.0.0.51:/tmp

数据库MySQL命令
cd /tmp
gzip xf bak.sql.tar.gz
mysql -uroot -poldboy123 -e "show databases like 'wordpress';"
mysql -uroot -poldboy123 -e "use wordpress;show tables;"
mysql -uroot -poldboy123
grant all on wordpress.* to wordpress@'172.16.1.%' identified by '123456';
flush privileges;
select user,host from mysql.user;


更改.8配置文件 wp-config.php
32 define('DB_HOST', '172.16.1.51');
关闭本地数据库
/etc/init.d/mysqld stop
chkconfig mysqld off
成功。

2、将blog的资源文件迁移到NFS
[iyunv@web01 blog]# tree wp-content/uploads/
资源目录为：wp-content/uploads/

nfs命令
echo "/uploads 172.16.1.0/24(rw,sync)" /etc/exports
MySQL数据库命令
mount -t nfs  172.16.1.31:/uploads /application/nginx/html/blog/
