1. Build your own yum warehouse, which is network source and local source respectively.
Network Source:
1. First create a yum warehouse:
[centos@localhost ~]$ yum install createrepo
2. Disable the original yum network source.
[root@localhost yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
3. Edit CentOS-Base.repo
[base] name=Base Repo on mirrors.bjtu.edu.cn baseurl=http://mirror.bjtu.edu.cn/centos/$releasever/os/$basearch gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 [updates] name=Base Repo on mirrors.bjtu.edu.cn baseurl=http://mirror.bjtu.edu.cn/centos/$releasever/updates/$basearch gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 [extras] name=Base Repo on mirrors.bjtu.edu.cn baseurl=http://mirror.bjtu.edu.cn/centos/$releasever/extras/$basearch gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 [centosplus] name=Base Repo on mirrors.bjtu.edu.cn baseurl=http://mirror.bjtu.edu.cn/centos/$releasever/centosplus/$basearch gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
Local source:
1. Mount the disc and mirror it locally.
[centos@localhost ~]$ mount -r /dev/cdrom /home/os
2. Modify CentOS-Media.repo
[c7-media] name=CentOS-$releasever - Media baseurl=file:///media/CentOS/ file:///home/os/ file:///media/cdrecorder/ gpgcheck=1 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
3. Disable network yum source
[root@localhost yum.repos.d]# mv CentOS-Base.repo CentOS-Media.repo.Bak
2. Compile and install http2.4 for normal access and submit compilation steps and results.
1. Check if httpd2.4 is installed
[root@nihao ~]# rpm -qa | grep httpd
2. Install development tools
[root@nihao ~]# yum groupinstall 'Development Tools'
3. Download the httpd2.4 installation package
Web site link: https://httpd.apache.org/download.cgi
4. Unzip to Local
[root@nihao sources]# tar xvf httpd-2.4.43.tar.gz
5. Download and install the apr package
[root@localhost ~]# wget http://archive.apache.org/dist/apr/apr-1.7.0.tar.gz [root@localhost download]# tar -xvf ./apr-1.7.0.tar.gz [root@localhost ~]# ./configure prefix=/usr/local/apr [root@localhost download]# make && make install
6. Download and install the apr-util package
[root@localhost ~]# wget http://archive.apache.org/dist/apr/apr-util-1.3.4.tar.gz
[root@localhost download]# tar -xvf ./apr-util-1.3.4.tar.gz
[root@localhost ~]# ./configure prefix=/usr/local/apr --with-apr=/usr/local/apr/bin
[root@localhost download]# make && make install
7. Download the pcre package
Web site link: https://ftp.pcre.org/pub/pcre/
8. Install the pcre package
[root@localhost download]# unzip pcre2-10.35.zip [root@localhost pcre2-10.35]# ./configure prefix=/usr/local/pcre [root@localhost pcre2-10.35]# make && make install
9. Install http2.4
Note: During installation:
exports.c:2436:13: error: redefinition of 'ap_hack_apr_xml_quote_elem' const void *ap_hack_apr_xml_quote_elem = (const void *)apr_xml_quote_elem; ^ exports.c:2048:13: note: previous definition of 'ap_hack_apr_xml_quote_elem' was here const void *ap_hack_apr_xml_quote_elem = (const void *)apr_xml_quote_elem; ^ exports.c:2437:13: error: redefinition of 'ap_hack_apr_xml_insert_uri' const void *ap_hack_apr_xml_insert_uri = (const void *)apr_xml_insert_uri; ^ exports.c:2049:13: note: previous definition of 'ap_hack_apr_xml_insert_uri' was here const void *ap_hack_apr_xml_insert_uri = (const void *)apr_xml_insert_uri; ^ exports.c:2446:13: error: redefinition of 'ap_hack_apu_version' const void *ap_hack_apu_version = (const void *)apu_version; ^ exports.c:2058:13: note: previous definition of 'ap_hack_apu_version' was here const void *ap_hack_apu_version = (const void *)apu_version; ^ exports.c:2447:13: error: redefinition of 'ap_hack_apu_version_string' const void *ap_hack_apu_version_string = (const void *)apu_version_string;
Solution: Installing apr-util1.4.1 or above caused an error when I installed apr-util1.3.4.
[root@localhost httpd-2.4.43]# ./configure --prefix=/usr/local/apache --with-pcre=/usr/local/pcre --with-apr-util=/usr/local/apr-util [root@localhost httpd-2.4.43]# make && make install
10. Start the httpd service to verify successful installation
[root@localhost ~]# /usr/local/apache/bin/apachectl start [root@localhost ~]# curl http://localhost:80 <html><body><h1>It works!</h1></body></html>
3. Create a 2G file system with a block size of 2048byte, 1% free space reserved, file system ext4, volume labeled TEST, which requires that this partition be automatically mounted to the / test directory after booting up, and has the acl mount option by default
1. Create a 2G file system partition
[root@localhost ~]# fdisk /dev/sdb Command (m for help): n Select (default p): p First sector (4196352-20971519, default 4196352): Using default value 4196352 Last sector, +sectors or +size (4196352-20971519, default 20971519): +20G
2. Set block size to 2048 byte, reserve 1% free space, file system ext4, volume labeled TEST
[root@localhost ~]# mke2fs -t ext4 -L 'TEST' -m 1 -b 2048 /dev/sdb1
3. Automatically mount to / test directory after boot-up, with acl mount option by default
[root@localhost etc]# cat /etc/fstab UUID=TEST /home/other ext4 defaults,acl 0 0
4. Create a 20G VG named testvg with at least two PV s; require a PE size of 16MB, and then create a 5G logical volume testlv in the volume group; mount in the / users directory
1. Creating a 20G VG named testvg with two PV s requires a PE size of 16MB
[root@localhost ~]# pvcreate /dev/sdc1 /dev/sdc2 Physical volume "/dev/sdc1" successfully created. Physical volume "/dev/sdc2" successfully created. [root@localhost ~]# vgcreate --physicalextentsize 16M testvg /dev/sdc1 /dev/sdc2 Volume group "testvg" successfully created
2. Create a 5G logical volume testlv; mount to / users directory
[root@localhost ~]# lvcreate -L 5G -n testlv testvg [root@localhost testvg]# mount /dev/testvg/testlv /users/
