Loading... ## Step 1: enable `EPEL` The instructions differ depending on whether you are on Red Hat or CentOS. The second step is only necessary on Red Hat. ### Step 1: install `EPEL` package ```bash sudo yum install -y yum-utils sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-$(< /etc/redhat-release tr -dc '0-9.'|cut -d \. -f1).noarch.rpm sudo yum-config-manager --enable epel sudo yum clean all && sudo yum update -y ``` ### Step 2 (RHEL only): enable the `optional` repository Enable the optional repository (rhel-8-server-optional-rpms). This can be done by enabling the RHEL optional [subchannel](https://access.redhat.com/solutions/11312) for RHN-Classic. For certificate-based subscriptions see [Red Hat Subscription Management Guide](https://access.redhat.com/documentation/en-US/Red_Hat_Subscription_Management/1/html/RHSM/entitlements-and-yum.html#supplementary-repos). The following commands may be helpful, but are not thoroughly tested. ```bash sudo subscription-manager register --username $RHN_USERNAME --password $RHN_PASSWORD --auto-attach sudo subscription-manager repos --enable rhel-8-server-optional-rpms ``` ## Step 2: repair potential system issues These commands will fix common issues that prevent yum from installing `Passenger` ```bash # Ensure curl and nss/openssl are sufficiently up-to-date to talk to the repo sudo yum update -y date # if the output of date is wrong, please follow these instructions to install ntp sudo yum install -y ntp sudo chkconfig ntpd on sudo ntpdate pool.ntp.org sudo service ntpd start ``` ### Step 3: install Passenger packages These commands will install Passenger dynamic `Nginx` module through Phusion's YUM repository. > If you want to use our packaged Nginx module, you must use your distro's provided Nginx package. If for example you have the repo provided by NGINX setup, you will instead need to compile a dynamic module compatible with that Nginx. ```bash # Install various prerequisites sudo yum install -y curl # Add our el8 YUM repository sudo curl --fail -sSLo /etc/yum.repos.d/passenger.repo https://oss-binaries.phusionpassenger.com/yum/definitions/el-passenger.repo # Install Passenger dynamic Nginx module sudo yum install -y nginx-mod-http-passenger || sudo yum-config-manager --enable cr && sudo yum install -y nginx-mod-http-passenger ``` ### Step 4: restart Nginx Now that the Passenger Nginx module is installed, restart Nginx to ensure that Passenger is activated: ```bash sudo systemctl restart nginx ``` ### Step 5: check installation After installation, please validate the install by running sudo /usr/bin/passenger-config validate-install. For example: ```bash sudo /usr/bin/passenger-config validate-install * Checking whether this Phusion Passenger install is in PATH... ✓ * Checking whether there are no other Phusion Passenger installations... ✓ ``` All checks should pass. If any of the checks do not pass, please follow the suggestions on screen. Finally, check whether Nginx has started the Passenger core processes. Run sudo /usr/sbin/passenger-memory-stats. You should see Nginx processes as well as Passenger processes. For example: ```bash sudo /usr/sbin/passenger-memory-stats Version: 5.0.8 Date : 2015-05-28 08:46:20 +0200 ... ---------- Nginx processes ---------- PID PPID VMSize Private Name ------------------------------------- 12443 4814 60.8 MB 0.2 MB nginx: master process /usr/sbin/nginx 12538 12443 64.9 MB 5.0 MB nginx: worker process ### Processes: 3 ### Total private dirty RSS: 5.56 MB ----- Passenger processes ------ PID VMSize Private Name -------------------------------- 12517 83.2 MB 0.6 MB PassengerAgent watchdog 12520 266.0 MB 3.4 MB PassengerAgent server 12531 149.5 MB 1.4 MB PassengerAgent logger ... ``` If you do not see any `Nginx` processes or `Passenger` processes, then you probably have some kind of installation problem or configuration problem. Please refer to the [troubleshooting guide](https://www.phusionpassenger.com/docs/advanced_guides/troubleshooting/nginx/troubleshooting/ruby/). ## Step 6: update regularly Nginx updates, Passenger updates and system updates are delivered through the YUM package manager regularly. You should run the following command regularly to keep them up to date: ```bash sudo yum update ``` After an update, you should restart Nginx. Doing so will automatically restart Passenger too. # Reference * [Installing Passenger Red Hat 8 / CentOS 8 (with RPM)](https://www.phusionpassenger.com/docs/advanced_guides/install_and_upgrade/nginx/install/oss/el8.html) 最后修改：2020 年 09 月 22 日 © 允许规范转载 赞 0 如果觉得我的文章对你有用，请随意赞赏
