如何解决php5.4 系统升级出错问题？
CentOS7 PHP5.4 升级 PHP5.6 缺少libmcrypt问题解决办法
系统为CentOS7.3，安装PHP后，版本为5.4，当进行升级5.6时发生错误：报错缺少libmcrypt.so.4()(64bit)库
需要安装libmcrypt，libmcrypt-devel：
yum install libmcrypt libmcrypt-devel直接输入以上指令，出错！问题为EPEL源未更新到最新版本。
需要升级EPEL源：
命令：yum -y install epel-release
yum -y install epel-releaseLoaded plugins: fastestmirror, langpacksLoading mirror speeds from cached hostfile * base: 100.125.0.40 * extras: 100.125.0.40 * updates: 100.125.0.40 * webtatic: us-east.repo.webtatic.comResolving Dependencies--> Running transaction check---> Package epel-release.noarch 0:7-9 will be updated---> Package epel-release.noarch 0:7-11 will be an update--> Finished Dependency ResolutionDependencies Resolved======================================================================================================== Package Arch Version Repository Size========================================================================================================Updating: epel-release noarch 7-11 extras 15 kTransaction Summary========================================================================================================Upgrade 1 PackageTotal download size: 15 kDownloading packages:Delta RPMs disabled because /usr/bin/applydeltarpm not installed.epel-release-7-11.noarch.rpm | 15 kB 00:00:00Running transaction checkRunning transaction testTransaction test succeededRunning transaction Updating : epel-release-7-11.noarch 1/2 Cleanup : epel-release-7-9.noarch 2/2 Verifying : epel-release-7-11.noarch 1/2 Verifying : epel-release-7-9.noarch 2/2Updated: epel-release.noarch 0:7-11Complete!从7-9 升级至7-11
EPEL最新是7-12，因此再输入一次上面的指令：
yum -y install epel-releaseLoaded plugins: fastestmirror, langpacksepel/x86_64/metalink | 8.6 kB 00:00:00epel | 5.4 kB 00:00:00(1/3): epel/x86_64/updateinfo | 1.0 MB 00:00:00(2/3): epel/x86_64/group_gz | 90 kB 00:00:01(3/3): epel/x86_64/primary_db | 6.9 MB 00:01:00Loading mirror speeds from cached hostfile * base: 100.125.0.40 * epel: mirrors.aliyun.com * extras: 100.125.0.40 * updates: 100.125.0.40 * webtatic: uk.repo.webtatic.comResolving Dependencies--> Running transaction check---> Package epel-release.noarch 0:7-11 will be updated---> Package epel-release.noarch 0:7-12 will be an update--> Finished Dependency ResolutionDependencies Resolved======================================================================================================== Package Arch Version Repository Size========================================================================================================Updating: epel-release noarch 7-12 epel 15 kTransaction Summary========================================================================================================Upgrade 1 PackageTotal download size: 15 kDownloading packages:Delta RPMs disabled because /usr/bin/applydeltarpm not installed.epel-release-7-12.noarch.rpm | 15 kB 00:00:00Running transaction checkRunning transaction testTransaction test succeededRunning transaction Updating : epel-release-7-12.noarch 1/2 Cleanup : epel-release-7-11.noarch 2/2 Verifying : epel-release-7-12.noarch 1/2 Verifying : epel-release-7-11.noarch 2/2Updated: epel-release.noarch 0:7-12完成升级7-12。
再次安装
libmcrypt，libmcrypt-devel：
yum install libmcrypt libmcrypt-devel
yum install libmcrypt libmcrypt-develLoaded plugins: fastestmirror, langpacksLoading mirror speeds from cached hostfile * base: 100.125.0.40 * epel: my.mirrors.thegigabit.com * extras: 100.125.0.40 * updates: 100.125.0.40 * webtatic: uk.repo.webtatic.comResolving Dependencies--> Running transaction check---> Package libmcrypt.x86_64 0:2.5.8-13.el7 will be installed---> Package libmcrypt-devel.x86_64 0:2.5.8-13.el7 will be installed--> Finished Dependency ResolutionDependencies Resolved======================================================================================================== Package Arch Version Repository Size========================================================================================================Installing: libmcrypt x86_64 2.5.8-13.el7 epel 99 k libmcrypt-devel x86_64 2.5.8-13.el7 epel 13 kTransaction Summary========================================================================================================Install 2 PackagesTotal download size: 112 kInstalled size: 302 kIs this ok [y/d/N]: yDownloading packages:(1/2): libmcrypt-2.5.8-13.el7.x86_64.rpm | 99 kB 00:00:00(2/2): libmcrypt-devel-2.5.8-13.el7.x86_64.rpm | 13 kB 00:00:00--------------------------------------------------------------------------------------------------------Total 1.2 MB/s | 112 kB 00:00:00Running transaction checkRunning transaction testTransaction test succeededRunning transaction Installing : libmcrypt-2.5.8-13.el7.x86_64 1/2 Installing : libmcrypt-devel-2.5.8-13.el7.x86_64 2/2 Verifying : libmcrypt-devel-2.5.8-13.el7.x86_64 1/2 Verifying : libmcrypt-2.5.8-13.el7.x86_64 2/2Installed: libmcrypt.x86_64 0:2.5.8-13.el7 libmcrypt-devel.x86_64 0:2.5.8-13.el7Complete!成功！
最后升级PHP，指令：
yum install -y php56w php56w-opcache php56w-xml php56w-mcrypt php56w-gd php56w-devel php56w-mysql php56w-intl php56w-mbstring感谢各位的阅读，以上就是“怎么解决php5.4系统升级出错问题”的内容了，经过本文的学习后，相信大家对怎么解决php5.4系统升级出错问题这一问题有了更深刻的体会，具体使用情况还需要大家实践验证。这里是编程网，小编将为大家推送更多相关知识点的文章，欢迎关注！
