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

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
