JAVA Image Guide

By default, network access is turned off to a ECS instance. You can specify rules in a security group that allows access from an IP address range, port, or ECS security group.

You must specify port numbers (for TCP):

  • 22 (ssh)
  • 80 (http)
  • 443 (https)
  • 21, 20000~30000 (ftp)

How do use scripts to optimize the parameters​

Because this image was build based on 1 Core 1G ECS,the configuration and parameters for MySQL/MariaDB,PHP are original without any change, highly recommended If this is not the case, run the following optimization script:

Exec command
sudo /root/oneinstack/optimize.sh
warning
  • Do not execute bash optimize.sh (or sh) for documentation commands
  • It may take 1 minute to wait, please do not interrupt
  • This script will automatically optimize Nginx, MySQL, JVM and other parameters according to the system configuration
e.g.: Execute command process
[root@WeiLiu ~]# sudo /root/oneinstack/optimize.sh
Shutting down MySQL..                                      [  OK  ]
Starting MySQL.                                            [  OK  ]

Create a database user​

danger

For security purposes, we usually create a unique database connection account for each web application(Account name can not be root).

E.g: Add a user named: db_user，password: 123456, Authorization for the localhost to the oneinstack database all permissions, the commands are as follows:

Exec command
mysql -uroot -p #Tip: Enter mysql console
Enter password: #Tip: Enter mysql root password
MySQL [(none)]> grant all privileges on db_name.* to db_user@'localhost' identified by 'db_pass';
MySQL [(none)]> flush privileges;
MySQL [(none)]> exit; #Tip: quit mysql console,Notice the semicolon at the end
e.g.: Execute command process
[root@WeiLiu ~]# mysql -uroot -p
Enter password: 

MySQL [(none)]> grant all privileges on db_name.* to db_user@'localhost' identified by 'db_pass';
Query OK, 0 rows affected, 2 warnings (0.01 sec)

MySQL [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MySQL [(none)]> exit;
Bye

How to setup a remote DB connection​

For security reasons, OneinStack only allows the cloud host localhost to connect to the database，if you need a remote connection to the database，the following operations are required:

caution

The cloud host security group port, iptables (some cloud hosts do not have iptables enabled and can be skipped), and grant authorized users are indispensable.

1. You must open port 3306 for Security groups​

Security groups document URL: Alibabacloud Security group

2. Open iptables port 3306​

tip

V2.0 or later, iptables is not enabled, please ignore this step 2

Reference: About iptables firewall

3. Database authorization​

caution

Create a new account for remote connection (the account name cannot be root, the remote database account is not recommended to be root, if you need root remote connection, please update the corresponding row of the mysql.user table).

e.g.: Add a user named db_user, password db_pass，Authorized as % (% Represents all ip can connect, you can set the designated ip) db_name database all authority, the commands are as follows

Exec command
mysql -uroot -p
MySQL [(none)]> grant all privileges on db_name.* to db_user@'%' identified by 'db_pass';
MySQL [(none)]> flush privileges;
MySQL [(none)]> exit;
e.g.: Execute command process
[root@WeiLiu ~]# mysql -uroot -p
Enter password: 

MySQL [(none)]> grant all privileges on db_name.* to db_user@'%' identified by 'db_pass';
Query OK, 0 rows affected, 2 warnings (0.01 sec)

MySQL [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MySQL [(none)]> exit;

How to deploy a java website on a server​

caution

Ftp upload code do not need to modify permissions，default is already www; Download the code in server, you must modify the site root and subdirectories,Directory file permissions are www; If there is a problem with site permissions，Please refer to《About site root permissions》

e.g.: demo.war deployment JAVA website
[root@WeiLiu ~]# ls
demo.war  oneinstack  ReadMe
[root@WeiLiu ~]# cd /data/wwwroot/demo.linuxeye.com
[root@WeiLiu demo.linuxeye.com]# jar xf /root/demo.war
[root@WeiLiu demo.linuxeye.com]# ls -l
total 4
drwxr-xr-x 4 root root 4096 Oct 30 19:26 demo
[root@WeiLiu demo.linuxeye.com]# mv demo/* .
[root@WeiLiu demo.linuxeye.com]# rm -rf demo
[root@WeiLiu demo.linuxeye.com]# chown -R www.www ./
[root@WeiLiu demo.linuxeye.com]# systemctl restart tomcat

** Create deploy JAVA website **

The default mirror is static and dynamic separation, that is, nginx handles static resources (JSS, CCC, pictures, etc.), and the rest goes to Tomcat processing. The default (non binding domain) corresponding to the site root directory /data/wwwroot/default (not webapps), the deployment of code recommendations will pack War (such as example.war, jar xf example.war, unzip: note that permissions must be WWW), the code into the corresponding web site root directory.

  • If you upload the code, the directory structure is /data/wwwroot/default/WEB-INF, and the access address is: http://IP
  • If you upload the code, the directory structure is: /data/wwwroot/default/example/WEB-INF, access the web site address is: http://IP/example.
caution
  • The war package can also be uploaded to the corresponding web root without decompression, but you must pay attention to access paths and static resource directory issues. If you visit the site, the static loading of resources may be the reason is not, do separate static resources directly with nginx, please confirm whether nginx can find relevant static resources (nginx web site root directory: /data/wwwroot/default)
  • If the vhost.sh binds the domain name, such as www.example.com, the tool automatically generates the corresponding root directory: /data/wwwroot/www.example.com, put the code in this directory.
  • Tomcat parameter, please modify: /usr/local/tomcat/bin/setenv.sh

About site root permissions​

Webroot permissions to follow:：

file 644, folder 755, Permissions Users and groups www

If there is a file permissions problem, execute the following three commands:

Exec command
chown -R www.www /data/wwwroot/
find /data/wwwroot/ -type d -exec chmod 755 {} \;
find /data/wwwroot/ -type f -exec chmod 644 {} \;

How to increase the maximum memory size of Redis?​

Edit the Memcached configuration file
vi /lib/systemd/system/memcached.service

Environment=CACHESIZE=256 #Unit MB

Memcached configuration takes effect

Change Redis listening port​

Edit the Redis configuration file
vi /usr/local/redis/etc/redis.conf

bind 127.0.0.1 change to bind 0.0.0.0

tip

systemd is the latest initialization system (init) of the Linux system. Its function is to improve the startup speed of the system, start as few processes as possible, and start as many processes as possible concurrently. The corresponding process management command is systemctl, which is supported by CentOS7 and Ubuntu/Debian. It is recommended to use sytemd to manage services.

Restart Redis to take effect
systemctl restart redis-server

Change Memcached listening port​

Edit the Memcached configuration file
vi /lib/systemd/system/memcached.service

OPTIONS="-l 127.0.0.1" change to OPTIONS=""

Memcached configuration takes effect
systemctl daemon-reload
systemctl restart memcached
