第七章中部署方案存在的問(wèn)題：

1. 一次只能選擇一個(gè)微服務(wù)部署
2. 只有一臺(tái)生產(chǎn)者部署服務(wù)器
3. 每個(gè)微服務(wù)只有一個(gè)實(shí)例，容錯(cuò)率低

優(yōu)化方案：

1. 在一個(gè)Jenkins工程中可以選擇多個(gè)微服務(wù)同時(shí)發(fā)布
2. 在一個(gè)Jenkins工程中可以選擇多臺(tái)生產(chǎn)服務(wù)器同時(shí)部署
3. 每個(gè)微服務(wù)都是以集群高可用形式部署

優(yōu)化Jenkins工程中可以選擇多個(gè)微服務(wù)

安裝 Extended Choice Parameter 插件，到項(xiàng)目配置中，可以看到選擇參數(shù)多了一個(gè)選項(xiàng)

優(yōu)化Jenkins工程中可以選擇多臺(tái)生產(chǎn)服務(wù)器

1.在 Manager Jenkins->Configure System->Publish over SSH->在添加服務(wù)器

2.在到項(xiàng)目配置中添加服務(wù)器選擇,和工程中選擇多個(gè)微服務(wù)是類似的
