zato建立集群

注：

• SQL ODB和Cluster’s config需要首先依次创建，其他三个次序随意
• 对不熟悉的命令，使用server create *** -h 查看帮助文档

1. SQL  ODB

• Create a user for Zato servers

$ sudo su - postgres # OS X users may skip it
$ createuser --no-superuser --no-createdb --no-createrole zato1
$ createdb --owner=zato1 zato1
$ psql --dbname zato1 --command="ALTER ROLE zato1 WITH PASSWORD ‘l‘"

• (PostgreSQL only) Create a separate schema for Zato

[email protected]:/home/dimite$ psql
psql (9.3.9)
Type "help" for help.

postgres=# CREATE SCHEMA zato_schema;
CREATE SCHEMA

• Make Zato user the owner of the database created or grant it permissions to issue DDL statements
• Issue the zato create odb command

zato create odb postgresql --odb_host localhost --odb_port 5432 --odb_user zato1 --odb_db_name zato1 --postgresql_schema zato_schema

删除的话，把create换成delete

• Revoke any DDL rights given to the Zato user

2. Cluster’s config

zato create cluster --odb_host localhost --odb_port 5432 --odb_user zato1 --odb_db_name zato1 --postgresql_schema zato_schema postgresql localhost 11223 20151 localhost 6379 PROD3 techacc1

3. Web admin

ca

[email protected]:~$ zato ca create ca crypto
OK
[email protected]:~$ cd crypto/
[email protected]:~/crypto$ ls
ca-material  out-cert  out-csr  out-priv  out-pub

ca-web-admin

[email protected]:~$ zato ca create web_admin ~/crypto
OK

web-admin

zato create web_admin --odb_host localhost --odb_port 5432 --odb_user zato1 --odb_db_name zato1 --postgresql_schema zato_schema ./web-admin postgresql ~/crypto/out-pub/web-admin-pub-2015-08-21_03-03-28.pem ~/crypto/out-priv/web-admin-priv-2015-08-21_03-03-28.pem ~/crypto/out-cert/web-admin-cert-2015-08-21_03-03-28.pem ~/crypto/ca-material/ca-cert.pem techacc1

建立新用户

zato create user ~/web-admin

4. Load-balancer

ca-lb

[email protected]:~$ zato ca create lb_agent ~/crypto/ zato_lb_agent1
OK

lb

zato create load_balancer ~/load-balancer ~/crypto/out-pub/lb-agent-pub-2015-08-21_03-25-08.pem ~/crypto/out-priv/lb-agent-priv-2015-08-21_03-25-08.pem ~/crypto/out-cert/lb-agent-cert-2015-08-21_03-25-08.pem ~/crypto/ca-material/ca-cert.pem

5. Servers

ca  server

[email protected]:~$ zato ca create server ~/crypto/ PROD3 server_132
OK

create server

zato create server --odb_host localhost --odb_port 5432 --odb_user zato1 --odb_db_name zato1 --postgresql_schema zato_schema ~/server_132 postgresql localhost 6379 ~/crypto/out-pub/PROD3-server_132-pub-2015-08-21_03-42-20.pem ~/crypto/out-priv/PROD3-server_132-priv-2015-08-21_03-42-20.pem ~/crypto/out-cert/PROD3-server_132-cert-2015-08-21_03-42-20.pem ~/crypto/ca-material/ca-cert.pem PROD3 server_132

Start it using the zato start command

[email protected]:~$ zato start web-admin
OK

注：每个集群由多个共享同一个SQL和Redis数据库的服务器构成。因此在普通的机子上创建server时，只需要安装zato，再创建server。其中的ODB和redis所在机器的ip和port要根据具体情况写。

把server加入到负载平衡中：位置：Clusters -> (pick one from the table) -> Servers -> Add to LB/Remove from LB/Delete
