Construction and debugging of LAMP multi-computer scheme
What this article shares with you is the construction and debugging of LAMP multi-machine solution. I believe that most people have not yet learned this skill. In order to let you learn, I have summarized the following content for you. Without saying much, let's read on.
1.LAMP multi-machine solution to build the scene
two。 Skills that should be paid attention to in building, modulating, and testing environmental scenarios
1) after the 141host on the virtual machine is cloned successfully, the new host is reset to the new IP (192.168.153.141) address.
2) change the hostname of the 141host, such as # hostnamectl set-hostname LAMP
3) authorize the forum database in the 143 database server to the 141 host, otherwise the following error occurs, as shown in the following figure:
4) the problem of being unable to connect to the database server (192.168.153.143) will now be resolved:
[root@sky9890] # mysql-uroot-p
Enter password:
MySQL [(none)] > use mysql
Database changed
MySQL [mysql] > select Host from user where user='root'
+-- +
| | Host |
+-- +
| | 127.0.0.1 | |
| | 192.168.153.142 | |
| |:: 1 |
| | localhost |
| | localhost.localdomain |
+-- +
MySQL [mysql] > GRANT ALL ON *. * to root@'192.168.153.141' IDENTIFIED BY'*; # Authorization
MySQL [mysql] > flush privileges
MySQL [mysql] > select Host from user where user='root'
+-- +
| | Host |
+-- +
| | 127.0.0.1 | |
| | 192.168.153.141 | |
| | 192.168.153.142 | |
5) successful test, as shown below:
6) when starting the server, it is necessary to start the necessary services automatically, so it is necessary to train according to the job requirements and professionalism when studying at ordinary times.
[root@lamp sky9890] # cat / etc/rc.local
/ usr/local/apache2/bin/apachectl # apache service
[sky9890@redis_master ~] $ll / etc/rc.d/rc.local
-rw-r--r--. 1 root root 506 January 17 14:40 / etc/rc.d/rc.local
[root@lamp sky9890] # chmod + x / etc/rc.d/rc.local # must be granted for execution
