3.第一个里程（在web{01..03}操作）
3.1搭建wordpress网站
3.1.1安装软件
vim /etc/yum.repos.d/nginx.repo [nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/gpgcheck=1 （#安装有问题改成0或注释掉） enabled=1gpgkey=https://nginx.org/keys/nginx_signing.keymodule_hotfixes=trueyum install nginx -y #安装PHPyum remove php-mysql php php-fpm php-common rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmrpm ;-Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpmyum ;install -y php71w php71w-cli php71w-common php71w-devel php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm php71w-mysqlnd php71w-opcache php71w-pecl-memcached php71w-pecl-redis php71w-pecl-mongodb
3.1.2创建管理nginx的虚拟用户www
useradd -M -s /sbin/noloin www
3.1.2修改nginx管理用户
vim /etc/nginx/nginx.conf user www;
3.1.3修改配置文件PHP
vim /etc/php-fpm.d/www.conf user = www ##和nginx保持一致 group = www
3.1.4启动服务
systemctl start php-fpm.service systemctl enable php-fpm.service
3.1.5创建站点目录，修改权限
mkdir -p /blog/wordpresschown -R www.www /blog
3.1.6上传wordpress文件
rz wordpress.tartar xf wordpress.tarcd wordpressmv * /blog/wordpress
3.1.7编写nginx server配置文件
vim /etc/nginx/conf.d/blog.conf
server{
listen 80;
server_name blog.ashuai.com;
fastcgi_buffers 512 64k; #页面显示乱
location / {
root /blog/wordpress;
index index.php;
}
location ~ \.php$ {
root /blog/wordpress;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
}
}3.1.8启动nginx
systemctl start nginx systemctl enable nginx
4.第二个里程（在m01上操作）
yum install mariadb-server mariadb -y
systemctl start mariadb systemctl enable mariadb
mysqladmin -u root password 123
mysql -uroot -p123 create database wordpress; #授权给wordpress用户库的权限 grant all on wordpress.* to 'wordpress'@'172.16.1.%' identified by '123';
4.5连接数据库
访问blog.ashuai.com（web01）
vim /blog/wordpress/wp-config.php// ** MySQL 设置 - 具体信息来自您正在使用的主机 ** // /** WordPress数据库的名称 */define( 'DB_NAME', 'wordpress' );/** MySQL数据库用户名 */define( 'DB_USER', 'wordpress' );/** MySQL数据库密码 */define( 'DB_PASSWORD', '123' );/** MySQL主机 */define( 'DB_HOST', '172.16.1.51' );/** 创建数据表时默认的文字编码 */define( 'DB_CHARSET', 'utf8mb4' );
5.第三个历程共享存储NFS（在nfs01上操作）
5.1安装软件
yum install nfs-utils rpcbind -y
vim /etc/exports/blog/data 172.16.1.0/24(rw,sync)
mkdir -p /data/blogchown -R nfsnobody.nfsnobody /datachmod -R 777 /data
#先启动rpc服务 systemctl start rpcbind.service systemctl enable rpcbind.service #在启动nfs服务 systemctl start nfs systemctl enable nfs
yum install nfs-utils.x86_64 -y
mount -t nfs 172.16.1.31:/data/blog /blog/wordpress/wp-content/uploads/

7.搭建负载均衡服务器
7.1安装软件
vim /etc/yum.repos.d/nginx.repo [nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/gpgcheck=1 （#安装有问题改成0或注释掉） enabled=1gpgkey=https://nginx.org/keys/nginx_signing.keymodule_hotfixes=trueyum install nginx -y
useradd -M -s /sbin/noloin www
vim /etc/nginx/nginx.conf
user www;
##############################################
vim /etc/nginx/conf.d/proxy.conf
upstream shuai { #负载均衡
server 172.16.1.7:80;
server 172.16.1.8:80;
server 172.16.1.9:80;
}
server{
listen 80;
server_name blog.ashuai.com;
location / {
proxy_pass http://shuai; #反向代理 proxy_set_header Host $host;
}
}systemctl start nginx systemctl enable nginx
