拉起数据库集群
如何定义并拉起PostgreSQL数据库集群
剧本概览
完成了基础设施部署后，您可以通过pgsql.yml完成数据库集群的部署。
您需要首先在 Pigsty配置文件完成数据库集群的定义，然后通过执行pgsql.yml将变更具现化。
./pgsql.yml # 在所有清单中的机器上执行数据库集群初始化操作（危险！）
./pgsql.yml -l pg-test # 在 pg-test 分组下的机器执行数据库集群初始化（推荐！）
./pgsql.yml -l pg-meta,pg-test # 同时初始化pg-meta与pg-test两个集群
./pgsql.yml -l 10.10.10.11 # 初始化10.10.10.11这台机器上的数据库实例
注意事项
-
使用不带参数的
pgsql.yml虽然很爽，但在生产环境中是一个高危操作强烈建议您在执行时添加
-l参数，限制命令执行的对象范围。 -
您可以将元节点当成普通节点复用，即在元节点上定义并创建PostgreSQL数据库。
默认沙箱环境中，执行
./pgsql.yml会同时完成pg-meta与pg-test的初始化工作。 -
在从库初始化时，您必须确保主库必须已经完成初始化，或者主库与其他从库同时进行初始化亦可。
保护机制
pgsql.yml提供保护机制，由配置参数pg_exists_action决定。当执行剧本前会目标机器上有正在运行的PostgreSQL实例时，Pigsty会根据pg_exists_action的配置abort|clean|skip行动。
abort：建议设置为默认配置，如遇现存实例，中止剧本执行，避免误删库。clean：建议在本地沙箱环境使用，如遇现存实例，清除已有数据库。skip： 直接在已有数据库集群上执行后续逻辑。- 您可以通过
./pgsql.yml -e pg_exists_action=clean的方式来覆盖配置文件选项，强制抹掉现有实例
选择性执行
您可以通过ansible的标签机制，可以选择执行剧本的一个子集。
例如，如果您只想执行负载均衡初始化的部分，则可以通过以下命令进行
./pgsql.yml --tags=haproxy
更多常用选择性执行的命令如下所示：
./pgsql.yml --tags=infra # 完成基础设施的初始化，包括机器节点初始化与DCS部署
./pgsql.yml --tags=node # 完成机器节点的初始化
./pgsql.yml --tags=dcs # 完成DCS：consul/etcd的初始化
./pgsql.yml --tags=dcs -e dcs_exists_action # 完成consul/etcd的初始化，抹除已有的consul agent
./pgsql.yml --tags=pgsql # 完成数据库与监控的部署
./pgsql.yml --tags=postgres # 完成数据库部署
./pgsql.yml --tags=monitor # 完成监控的部署
./pgsql.yml --tags=pg_biz_init,pg_biz_pgbouncer # 修改数据库与用户定义并应用。
./pgsql.yml --tags=proxy # 完成负载均衡器的部署，包括Haproxy与VIP
./pgsql.yml --tags=haproxy # 完成Haproxy的部署
./pgsql.yml --tags=vip # 完成VIP的部署
./pgsql.yml --tags=haproxy_config,haproxy_reload # 修改Haproxy配置并应用。
