###检查nginx配置文件
[root@web02 conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
log_format main ‘$remote_addr - $remote_user [$time_local]"$request" ‘
‘$status $body_bytes_sent"$http_referer" ‘
‘"$http_user_agent""$http_x_forwarded_for"‘;
access_log logs/access.log main;
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
includeextra/www.conf;
includeextra/bbs.conf;
includeextra/blog.conf;
includeextra/stat.conf;
}
###检查blog配置文件
[root@web02 conf]# pwd
/application/nginx/conf
[root@web02 conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.etiantian.org;
location / {
root html/blog;
index index.html index.htm;
}
}
[root@web02 conf]# ps -ef|grep nginx

[root@web02 conf]# curl blog.etiantian.org
blog 10.0.0.7
说明：利用nginx的location区块实现动态请求与静态请求的分别处理
[root@web02 conf]# vim extra/blog.conf
server {
listen 80;
server_name blog.etiantian.org;
# 静态请求处理的location
location / {
root html/blog;
index index.php index.html index.htm; <-- 需要注
意编辑修改默认首页文件
}
# 动态请求处理的location
location ~* .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
[root@web02 conf]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.10.2/conf/nginx.confsyntax is ok
nginx: configuration file/application/nginx-1.10.2/conf/nginx.conf test is successful
[root@web02 conf]# /application/nginx/sbin/nginx -s reload
nginx负责接收用户的请求，静态数据（html js css 图片等）请求的话nginx直接处理了，动态页面（php$）就转交给php-fpm处理了，有数据请求呢，php就会和mysql进行交互，如果加了memcached，那么php会首先到memcached去找，mem没有的话再到mysql去找，同时会在mem存一份，以供下次数据请求。
echo‘<?php phpinfo(); ?>‘ >/application/nginx/html/blog/test_info.php
[root@web02 blog]# curl -I blog.etiantian.org

说明：当php服务停止时，9000端口信息消失，即停止PHP错误报502错误，linux系统测试完毕后，建议利用浏览器进行最终测试，测试效果更明显
些。

下载部署wordpress博客程序（https://cn.wordpress.org/ 英文官网：https://www.wordpress.org/ ）
1, 网站下载： wget https://cn.wordpress.org/wordpress-4.5.1-zh_CN.tar.gz
2，网上下载上传到Linux： tar xf wordpress-4.5.1-zh_CN.tar.gz
mvwordpress/* /application/nginx/html/blog/
chown -Rwww.www /application/nginx/html/blog/
注意：确认hosts文件进行了解析
浏览器页面进行wordpress部署
vimwp-config.php 可以修改wordpress上的数据库连接参数信息

[root@web02 blog]#
浏览器中访问blog.etiantian.org/index.php
注：如果出现再次进入网站的时候可以使用强制刷新缓存文件（ctrl+F5）
在nginx上面传软件到新克隆的虚拟机（172.16.1.51DB01）上
[root@web02 ~]# cd /home/oldboy/tools/
[root@web02 ~]#scp -rpmysql-5.6.34-linux-glibc2.5-x86_64.tar.gz 172.16.1.51:/home/oldboy/tools/
###1.添加用户
useradd-s /sbin/nologin -M mysql
####2.解压 mysql 二进制包
cd/home/oldboy/tools
tarxf mysql-5.6.34-*-x86_64.tar.gz
####3.把MySQL 移动到 /application/
mkdir-p /application/
mv/home/oldboy/tools/mysql-5.6.34-*-x86_64 /application/mysql-5.6.34
####4.创建软连接
ln -s/application/mysql-5.6.34/ /application/mysql
####5.让MySQL用户管理 /application/mysql
chown-R mysql.mysql /application/mysql/
####6.安装这个软件 初始化数据库
#1.软件安装在哪里
#2.数据存放在哪里
#3.MySQL使用的用户谁？
/application/mysql/scripts/mysql_install_db--basedir=/application/mysql --datadir=/application/mysql/data --user=mysql
#####To start mysqld at boot time you have to copy
#####support-files/mysql.server to the right placefor your system
#####mysql启动脚本默认放在support-files/mysql.server
#####
#####记得给MySQL设置个密码
#####PLEASE REMEMBER TO SET A PASSWORD FOR THEMySQL root USER !
#####To do so, start the server, then issue the followingcommands:
#####
##### /application/mysql/bin/mysqladmin -u root password ‘new-password‘
##### /application/mysql/bin/mysqladmin -u root -h web01 password‘new-password‘
####7.复制启动脚本授权
cp/application/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod+x /etc/init.d/mysqld
####8.修改启动脚本和 mysql命令 中的路径
sed-i ‘s#/usr/local/mysql#/application/mysql#g‘ /application/mysql/bin/mysqld_safe/etc/init.d/mysqld
####9.复制默认的配置文件
\cp/application/mysql/support-files/my-default.cnf /etc/my.cnf
/etc/init.d/mysqldstart
###故障
##1./tmp权限
##2.主机名解析 hosts解析#ping 主机名
##3.一步一步执行
##
##/application/mysql/bin/mysql
##Welcome to the MySQL monitor. Commands end with ; or \g.
##Your MySQL connection id is 1
##Server version: 5.5.49 MySQL Community Server(GPL)
##mysql>
####10.PATH路径
echo‘export PATH=/application/mysql/bin:$PATH‘ >>/etc/profile
source/etc/profile
whichmysql
####11.加入开机自启动
chkconfig--add mysqld
chkconfigmysqld on
####12.给MySQL root用户设置密码
/application/mysql/bin/mysqladmin-u root password ‘oldboy123‘
####13.重新登录MySQL数据库
mysql-uroot -poldboy123
mysqldump-uroot -poldboy123 --all-databases >/tmp/mysqlbak.sql
ll/tmp/bak.sql -h
[root@web02 tools]# scp -rp /tmp/mysqlbak.sql 172.16.1.51:/tmp
当上面的命令执行成功后，切换到db数据库，将nginx服务器上推送的数据库同步到本地数据库。
mysql-uroot -poldboy123 </tmp/bak.sql
###db01添加新的用户
grantall on wordpress.* to wordpress@‘10.0.0.0/255.255.255.0‘identified by ‘oldboy123‘;
flushprivileges;
[root@DB tmp]# mysql -uroot -poldboy123</tmp/mysqlbak.sql
