红帽全球峰会第 2 章 将 3scale 2.5 升级到 2.6
先决条件
- 在项目中部署的 Red Hat 3scale API Management 2.5。
工具先决条件：
- base64
- jq
步骤
要将 3scale API 管理 2.5 升级到 2.6，请转至 3scale 部署的项目。
oc project <3scale-project>
$ oc project <3scale-project>然后，按照以下顺序执行这些步骤：
2.1. 为 3scale 项目创建备份目录
复制链接链接已复制到粘贴板!
使用以下步骤为 3scale 项目创建备份目录。请注意，{BACKUP_DIR} 是 3scale 备份机器上的位置。
步骤
创建备份目录：
mkdir ${BACKUP_DIR}mkdir ${BACKUP_DIR}Copy to Clipboard Copied! Toggle word wrap Toggle overflow 为您的备份创建目录和子目录：
mkdir ${BACKUP_DIR}/system-database ${BACKUP_DIR}/zync-database ${BACKUP_DIR}/system-redis ${BACKUP_DIR}/backend-redis ${BACKUP_DIR}/system-app ${BACKUP_DIR}/openshift mkdir ${BACKUP_DIR}/openshift/configmaps/ ${BACKUP_DIR}/openshift/deploymentConfigs ${BACKUP_DIR}/openshift/imageStreams ${BACKUP_DIR}/openshift/other/ ${BACKUP_DIR}/openshift/routes/ ${BACKUP_DIR}/openshift/secrets/ ${BACKUP_DIR}/openshift/services/mkdir ${BACKUP_DIR}/system-database ${BACKUP_DIR}/zync-database ${BACKUP_DIR}/system-redis ${BACKUP_DIR}/backend-redis ${BACKUP_DIR}/system-app ${BACKUP_DIR}/openshift mkdir ${BACKUP_DIR}/openshift/configmaps/ ${BACKUP_DIR}/openshift/deploymentConfigs ${BACKUP_DIR}/openshift/imageStreams ${BACKUP_DIR}/openshift/other/ ${BACKUP_DIR}/openshift/routes/ ${BACKUP_DIR}/openshift/secrets/ ${BACKUP_DIR}/openshift/services/Copy to Clipboard Copied!

2.1.1. 备份 system-database (MySQL)
复制链接链接已复制到粘贴板!
转储 system-mysql 数据库，并将转储存储在 ${BACKUP_DIR}/system-database/system-mysql-backup.gz 中：
oc rsh $(oc get pods -l 'deploymentConfig=system-mysql' -o json | jq -r '.items[0].metadata.name') bash -c 'export MYSQL_PWD=${MYSQL_ROOT_PASSWORD}; mysqldump --single-transaction -hsystem-mysql -uroot system' | gzip > ${BACKUP_DIR}/system-database/system-mysql-backup.gz
oc rsh $(oc get pods -l 'deploymentConfig=system-mysql' -o json | jq -r '.items[0].metadata.name') bash -c 'export MYSQL_PWD=${MYSQL_ROOT_PASSWORD}; mysqldump --single-transaction -hsystem-mysql -uroot system' | gzip > ${BACKUP_DIR}/system-database/system-mysql-backup.gz2.1.2. backup zync-database
复制链接链接已复制到粘贴板!

oc cp $(oc get pods -l 'deploymentConfig=system-redis' -o json | jq '.items[0].metadata.name' -r):/var/lib/redis/data/dump.rdb ${BACKUP_DIR}/system-redis/system-redis-dump.rdb
oc cp $(oc get pods -l 'deploymentConfig=system-redis' -o json | jq '.items[0].metadata.name' -r):/var/lib/redis/data/dump.rdb ${BACKUP_DIR}/system-redis/system-redis-dump.rdb2.1.4. 备份 backend-redis
复制链接链接已复制到粘贴板!
在 ${BACKUP_DIR}/ 中提取 backend-redis 转储
backend-redis /backend-redis-dump.rdb
oc cp $(oc get pods -l 'deploymentConfig=backend-redis' -o json | jq '.items[0].metadata.name' -r):/var/lib/redis/data/dump.rdb ${BACKUP_DIR}/backend-redis/backend-redis-dump.rdb
oc cp $(oc get pods -l 'deploymentConfig=backend-redis' -o json | jq '.items[0].metadata.name' -r):/var/lib/redis/data/dump.rdb ${BACKUP_DIR}/backend-redis/backend-redis-dump.rdb2.1.5. 备份 system-app 持久性数据
复制链接链接已复制到粘贴板!
在 ${BACKUP_DIR}/ 中复制 system-app 持久性数据：
system-app /
oc rsync $(oc get pods -l 'deploymentConfig=system-app' -o json | jq '.items[0].metadata.name' -r):/opt/system/public/system ${BACKUP_DIR}/system-app/
oc rsync $(oc get pods -l 'deploymentConfig=system-app' -o json | jq '.items[0].metadata.name' -r):/opt/system/public/system ${BACKUP_DIR}/system-app/2.1.6. 备份 DeploymentConfig
