lnmp项目搭建 wordpress wecenter

LNMP

1、拆分机器

机器的主机名	外网IP	内网IP
db01	192.168.15.51(不需要)	172.16.1.51
web01	192.168.15.7	172.16.1.7
web02	192.168.15.8	172.16.1.8
web03	192.168.15.9	172.16.1.9
nfs	192.168.15.31	172.16.1.31
backup	192.168.15.41	172.16.1.41

2、搭建backup服务器

 # 关闭防火墙、selinux
[root@backup ~]# systemctl disable --now firewalld
[root@backup ~]# setenforce 0
setenforce: SELinux is disabled
# 安装rsync
[root@backup ~]# yum install -y rsync
# 同一用户
[root@backup ~]# useradd -u888 www
[root@backup ~]# id www
uid=1000(www) gid=1000(www) groups=1000(www)

# 编写配置文件
[root@backup ~]# vi /etc/rsyncd.conf 
## 前端代码仓库、数据库备份、上传文件的备份
uid=www
gid=www
port=873
fake super=yes
use chroot=no
max connection=200
timeuot=600
ignore errors
read only=false
list=false
auth users=www
secrets file=/etc/rsync.passwd
log file=/var/log/rsyncd/log

# 创建仓库
[root@backup ~]# mkdir /backup
[root@backup ~]# mkdir /backup/web
[root@backup ~]# mkdir /backup/database
[root@backup ~]# mkdir /backup/download
[root@backup ~]# tree /backup/
/backup/
├── database
├── download
└── web

# 授权
[root@backup ~]# chown www.www -R /backup/

# 创建密码文件
[root@backup ~]# echo "yangge:520" > /etc/rsync.passwd
[root@backup ~]# chmod 600 /etc/rsync.passwd

# 启动
[root@backup ~]# systemctl enable --now rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.

3、搭建NFS服务器

# 软件 nfs-utils rpcbind

# 安装软件
[root@nfs ~]# yum install nfs-utils rpcbind -y

# 创建用户
[root@nfs ~]# useradd www -u888
[root@nfs ~]# id www
uid=888(www) gid=888(www) groups=888(www)

# 创建前端代码仓库、数据库备份、上传文件的备份
[root@backup ~]# mkdir /nfs
[root@backup ~]# mkdir /nfs/web
[root@backup ~]# mkdir /nfs/database
[root@backup ~]# mkdir /nfs/download
[root@nfs ~]# tree /nfs/
/nfs/
├── database
├── download
└── web

# 授权
[root@nfs ~]# chown www.www -R /nfs/


# 设置挂载点
[root@nfs ~]# vim /etc/exports
/nfs/web      172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)
/nfs/database 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)
/nfs/download 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)

# 启动
[root@nfs ~]# systemctl enable --now nfs-server.service 
Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.

# 检测
[root@nfs ~]# showmount -e
Export list for nfs:
/nfs/download 172.16.1.0/24
/nfs/database 172.16.1.0/24
/nfs/web      172.16.1.0/24

[root@nfs ~]# cat /var/lib/nfs/etab 
/nfs/download	172.16.1.0/24(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,all_squash,no_subtree_check,secure_locks,acl,no_pnfs,anonuid=888,anongid=888,sec=sys,rw,secure,root_squash,all_squash)
/nfs/database	172.16.1.0/24(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,all_squash,no_subtree_check,secure_locks,acl,no_pnfs,anonuid=888,anongid=888,sec=sys,rw,secure,root_squash,all_squash)
/nfs/web	172.16.1.0/24(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,all_squash,no_subtree_check,secure_locks,acl,no_pnfs,anonuid=888,anongid=888,sec=sys,rw,secure,root_squash,all_squash)

4、搭建数据库

# 软件：mariadb

# 安装
[root@db01 ~]# yum install mariadb* -y

# 启动
[root@db01 ~]# systemctl enable --now mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

# 创建密码
[root@db01 ~]# mysqladmin -uroot passw
