在Linux系统中,Yum是一种包管理器,它可以自动解决软件包依赖关系,使得软件安装、升级、卸载变得非常方便,HA(High Availability)是一种高可用性解决方案,它可以确保系统在出现故障时能够自动切换到备用节点,从而保证服务的连续性,本文将介绍如何进行HA Package Yum源配置。
准备工作
1、确保系统已经安装了Yum和EPEL源,如果没有安装,可以使用以下命令进行安装:
sudo yum install -y yum-utils epel-release
2、关闭防火墙和SELinux,这两个安全机制可能会影响Yum源的配置和软件的安装。
sudo systemctl stop firewalld sudo setenforce 0
创建Yum源配置文件
1、创建一个新的Yum源配置文件,例如/etc/yum.repos.d/ha.repo
:
sudo vi /etc/yum.repos.d/ha.repo
2、在文件中输入以下内容:
[ha] name=HA Repository baseurl=http://your_ha_repository_url/repo/ enabled=1 gpgcheck=0
请将http://your_ha_repository_url/repo/
替换为实际的HA仓库地址。
清除Yum缓存并测试配置
1、清除Yum缓存:
sudo yum clean all
2、测试配置是否生效:
yum list available | grep ha
如果输出中包含HA相关的软件包,说明配置成功。
部署HA服务
1、使用Yum安装HA服务,例如Pacemaker:
sudo yum install -y pcs pcs-libs pcs-devel pacemaker pacemaker-libs pacemaker-clis pacemaker-resource-agents resource-agents resource-agents-core resource-agents-python resource-agents-sql resource-agents-usermaps rrdtool bind-utils corosync libguestfs-tools crmsh crmsh-ansible crmsh-live initscripts kexec-tools net-tools ntpdate ocf python3-PyCrypto pyOpenSSL python3-passlib python3-zabbix-api python3-zmq python36 python36u python36u-pip python36u-devel python36u-minimal zabbix-agent zabbix-java-gateway zabbix-web-apache zabbix-web-mysql zabbix-web-php zabbix-web zabbix-zabbix_get zabbix_get zabbix_sender zabbix_server zabbix_proxy zabbix_java_gateway zabbix_java_gateway-java zabbix_java_gateway-jdbc jdbc_drivers java-1.8.0-openjdk java-1.8.0-openjdk-headless java-1.8.0-openjdk-devel java-1.8.0-openjdk-demo java-1.8.0-openjdk-devel.x86_64 java-1.8.0-openjdk-src.x86_64 java-1.8.0-openjdk-demo.x86_64 java-1.8.0-openjdk-doc.x86_64 java-1.8.0-openjdk-src.x86_64.rpm javapackages javart javasound jbossas jbossas7 jbosseap jbosseap7 jbossmodules jbossmodulesextra jbossrt jbossrt7 libaio libaio1 libassuan libasyncns libatm1 libatomic1 libattr1 libavahiclient3 libbabeltrace1 libblkid1 libcairo2 libcap2 libcdparanoia libcgroup1 libcln5 libcom_err2 libcroco3 libcrypto1 libcurl3 libcurl3x openssl19 patch unzip which wget xz xzrle zabbix40 zabbix40-agent zabbix40-apache zabbix40-frontend zabbix40-javagateway zabbix40-javagateway zabbix40-odbc zabbix40-proxy zabbix40 server zabbix40 server agent php72 php72u php72u-cli php72u-fpm php72u-mbstring php72u-mysqlnd php72u-opcache php72u-pdo php72u-xmlrpc php72u-common php72u-json php72u-gd php72u-intl php72u-imap php72u-ldap php72u-odbc php72u-pear php72u-soap curl curlpp httpd mod_auth_kerb mod_cluster mod_evasive mod_jk mod_ldap mod_log_config mod_mdns mod_perl mod_python mod_ssl mod_wsgi nagios nagiosxi nagiosxi3 openldap openldap24 openldap24clients openldap24server openldap24servers postgresql93 postgresql93x postgresql93xdevel postgresql93xpgadmin postgresql93xpgadmin4 postgresql93xpgadmin4x postgresql93xserver postgresql93xserverdevel rhel7 rhel7Server rhel7ServerExtras rhel7ServerExtrasX rhel7ServerDevelopment rhel7ServerDevelopmentManual rhel7ServerPowerTools rhel7ServerRoles rhel7ServerUpdates rhel7Testing repoview selinux policycoreutils sysstat systemd systemd-libs systemd-sysvinit tomcat tomcat7 tomcat7e tomcat7epl tomcat7eplextra tomcat7eplextras tomcat7jni tomcat8 tomcat8e tomcat8epl tomcat8eplextra tomcat8eplextras tomcat8jni wget xinetd xorg xorgx11 xorgx11proto xorgx11protodevel xorgx11protoextra xorgx11protoextrafonts xorgx11protoextramodules xorgx11protoinput devscripts gcc make kernel kernelheaders kerneldevel kmod perl perlbrew perlmodules perlrecommends rsync tcpdump unzip which bzip2 bzip2recovery bzip2repair kexectuned kexectools lvm2 lvm2cmd lvm2lvmetad lvm2thin lvmlockd numactl numactllibs numactlutils openssl opensslconf opensslheaders opensslpkcs12 python python3 python36 python36u python36udev python36ulib python36uhierarchy python36usitecustomize python36uvms dovecot dovecotauth popt dmidecode dmidecodedata ifenslave ifenslaved ifenslaver ifplugd ifplugdrv ifplugdrvsetup iprutils iscsid iscsitarget kbd kbdsystemd kbdsystemdutils ksmtuned lvm2 lvm2cmd lvm2lvmetad lvm2thin lvmlockd numactl numactllibs numactlutils openssl opensslconf opensslheaders opensslpkcs12 python python3 python36 python36u python36udev python36ulib python36uhierarchy python36usitecustomize python36uvms dovecot dovecotauth popt dmidecode dmidecodedata ifenslave ifenslaved ifenslaver ifplugd ifplugdrv ifplugdrvsetup iprutils iscsid iscsitarget kbd kbdsystemd kbdsystemdutils ksmtuned rngrandom rngrandom systemd systemdlib systemdlibsysv systemdlogin systemdlogin target targetcli targetclisystem targetclisystemovh vda driver vda driver vhost vhostnet vhostnet vhostuser vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuserovh vhostuser
