linux9期架构-day30--使用变量搭建博客

需求

搭建博客
需要做到动态资源存储至数据库
静态资源存储至nfs
并且对nfs数据做好备份，结合sersync

环境准备

主机名	ip	角色
m01	10.0.0.61	ansible管理端
web01	10.0.0.7	nginx
web02	10.0.0.8	nginx
nfs	10.0.0.31	nfs共享存储及serync
rsync	10.0.0.41	备份数据
db01	10.0.0.51	数据库服务器

ansible前提准备文件

----------------------------------------------------------rsync准备
# 1. 准备rsync主配置文件
[root@m01 rsync]# cat rsyncd.conf 
uid = www												
gid = www												
port = 873
fake super = yes
use chroot = no
max connections = 200
timeout = 600
ignore errors
read only = false
list = false
auth users = rsync_backup
secrets file = /etc/rsync.passwd
log file = /var/log/rsyncd.log
#####################################
[backup]
comment = welcome to oldboyedu backup!
path = /backup

# 2.创建rsync用户密码对应文件
[root@m01 rsync]# cat rsync.passwd 
rsync_backup:123

------------------------------------------------------------nfs准备
# 1. 下载安装包到ansible
https://raw.githubusercontent.com/wsgzao/sersync/master/sersync2.5.4_64bit_binary_stable_final.tar.gz

# 2. 解压文件
[root@m01 rsync]# tar xf sersync2.5.4_64bit_binary_stable_final.tar.gz

# 3. 解压后的包重命名（作为sersync监控使用）
[root@m01 rsync]# mv GNU-Linux-x86/ sersync


---------------------------------------------------------web两台主机准备
# 1. 准备nginx和php安装包
-rw-r--r-- 1 root root 20453103 May 27 15:08 nginx.php.tar.gz

# 2. 准备wordpress博客压缩包
-rw-r--r-- 1 root root 11098483 May 20 14:38 wordpress-5.0.3-zh_CN.tar.gz

# 3. 准备nginx主配置文件（将用户改为了www）
-rw-r--r-- 1 root root      641 Jun 12 04:30 nginx.conf

# 4. 准备php配置文件（就是将文件中的用户和组改为了www）
-rw-r--r-- 1 root root    17962 Jun 12 04:32 www.conf

# 5. 准备nignx连接php文件（也是nginx的conf.d下的配置文件）
[root@m01 nginx]# cat nginx_blog.conf 
server {
        listen 80;
        server_name www.wp.com;
        root /code/wordpress;
        index index.php index.html;

        location ~ \.php$ {
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include /etc/nginx/fastcgi_params;

        }
}
