  1. Recently, I have been playing Apache mysql redis, etc., so I summarized the pitfalls I encountered. If I still encounter problems with the step-by-step installation, just leave a message at the bottom of the article and communicate together... I don't want to talk anymore, I'm starting to wave...
  3. Install centos 7After the system needs to be configured with IP and other information,
  5. vi /etc/sysconfig/network-scripts/ifcfg-eth0
  7. BOOTPROTO=static
  9. The way the network card obtains the ip address, Static (static ip address) dhcp (obtains the ip through the dhcp protocol)
  11. HWADDR=00:50:56:8E:47:EE network card physical address
  13. IPADDR=10.0.0.193 Network card IP address
  15. IPV6INIT=no Whether to enable IPV6
  17. IPV6_AUTOCONF=no
  19. NETMASK=255.255.255.0 Network mask corresponding to network card
  21. NETWORK=192.168.1.0 The network address corresponding to the network card
  23. ONBOOT=yes Whether to set this network interface when the system is started. When set to yes, this device will be activated when the system is started. Default setting is yes
  25. service network restart Restart the service or/etc/init.d/network restart
  27. What you need to change is IPADDR DNS1 GATEWAY DEVICE , just install your own machine and modify it.
  29. After the modifications are completed, the service network restarts and then ping Baidu to see if you can ping. If you can ping, it means you can surf the Internet.
  31. Next step, turn off the firewall. The wall of centos 7 is firewall
  33. systemctl stop firewall.service #Stop firewall
  34. systemctl disable firewall.service #Disable firewall from booting
  35. firewall-cmd-state #Check the default firewall state (not running is displayed after turning off, running is displayed after turning on)
  37. The next step is to upload the apache-dependent package. First, cd it to the root directory and then create a new tools folder, mkdir tools. Upload the dependent package and apache file to the tools below apr-1.6.3.tar.gz 、apr-util-1.6.1.tar.gz、pcre-8.41.zip、openssl-1.0.2n.tar.gz、httpd-2.4.29.tar.gz。
  39. Start decompressing:
  41. tar -xzvf apr-1.6.3.tar.gz
  43. tar -xzvf apr-util-1.6.1.tar.gz
  45. You need to install uzip yum install -y unzip zip first
  47. unzip pcre-8.41.zip
  49. Install apr-1.6.3
  51. Enter the installation directory
  53. cd /tools/apr-1.6.3/
  55. Install and compile
  57. Install gcc first yum -y install gcc
  59. ./ configure –prefix=/usr/local/apr
  61. rm: cannot remove 'libtoolT': No such file or director appears
  62. cd apr-1.6.3
  63. modify
  64. vi configure
  65. 9365 #RM=$ac_cv_prog_RM
  66. 9355 #ac_cv_prog_RM=“rm”
  68. make && make install will not report errors.
  70. Enter the installation directory
  72. cd /tools/apr-util-1.6.1/
  74. yum install -y libxml2-devel
  76. ./ configure –prefix=/usr/local/apr-util/ –with-apr=/usr/local/apr/bin/apr-1-config
  78. In CentOS7 minimum installation version, compile and install apr-util error:
  80. fatal error: expat.h: No such file or director
  82. Solution: yum install expat-devel
  84. make && make install
  86. Enter the installation directory
  88. cd /tools/pcre-8.41/
  90. Install and compile
  92. yum -y install gcc+ gcc-c++
  94. ./ configure –prefix=/usr/local/pcre
  96. make && make install
  98. Enter the installation directory
  100. tar -xvf openssl-1.0.2n.tar.gz
  102. cd openssl-1.0.2n
  104. yum install perl*
  106. ./ config -fPIC –prefix=/usr/local/openssl –openssldir=/usr/local/openssl
  108. make && make install
  110. Install gcc online
  112. #yum install gcc*
  114. cd /tools will install the package httpd-2.4.29Copy.tar.gz to the/tools directory
  116. #tar zxvf httpd-2.4.29.tar.gz
  118. #cd /tools/httpd-2.4.29
  120. yum install zlib-devel
  122. ./ configure –prefix=/opt/apache/apache-2.4.29 –enable-deflate –enable-expires –enable-headers –enable-ssl –enable-cgi –with-zlib –with-mpm=worker –enable-so –enable-rewrite –enable-module=shared –enable-mods-shared=most ap_cv_void_ptr_lt_long=no –with-apr=/usr/local/apr –with-apr-util=/usr/local/apr-util –with-pcre=/usr/local/pcre –with-ssl=/usr/local/openssl –enable-unique –enable-unique_id
  124. make && make install but an error was reported later

  158. ① Install libxml2-devel
  159. 1 [root@test_01 ~]# yum install -y libxml2-devel
  161. ② Delete the apr-util directory and recompile the installation
  163. 1
  165. 2
  167. 3
  169. 4
  171. 5
  174. [root@test_01 ~]#rm -rf /usr/local/apr-util
  176. [root@test_01 ~]# cd /tools/apr-util-1.6.1/
  178. [root@test_01 apr-util-1.6.1]# make clean
  180. [root@test_01 apr-util-1.6.1]#./ configure –prefix=/usr/local/apr-util –with-apr=/usr/local/apr
  182. [root@test_01 apr-util-1.6.1]#make && make install
  184. Recompile apache and install it will be ok
  186. Enter the post-installation directory:
  188. # cd /opt/apache/apache-2.4.29/bin
  191. Check the process mode:
  193. # ./ apachectl -l
  195. Compiled in modules:
  197. core.c
  199. worker.c
  201. http_core.c
  203. mod_so.c
  206. Start Apache Web Server:
  208. #./ apachectl start
  210. ServerName localhost:80
  212. Then the browser opens the address and it works appears
  214. Open the following to boot apache
  216. Stop Apache Web Server:
  218. #./ apachectl stop
  220. 1. Copy the apachectl file to/etc/init.d, and then add the link to/etc/rc.d/rc5.d.
  221. The order is as follows:
  223. cp /opt/apache/apache-2.4.29/bin/apachectl /etc/init.d/httpd
  226. ln -s /etc/init.d/httpd /etc/rc.d/rc5.d/S85httpd
  228. 2. Running chkconfig-list to find that there is no httpd in the list. Adding it by chkconfig-add httpd may remind you that the httpd service does not support chkconfig and you need to edit/etc/rc.d/init.d/httpd
  230. Add the following comment information:
  232. # chkconfig: 345 85 15
  234. # description: Activates/Deactivates Apache Web Server
  236. 345Represents which linux levels need to be activated httpd, and the activation sequence number is85, the closing sequence number is15
  238. 3. Run chkconfig-list, httpd exists, and you can use service httpd start and service httpd stop to start and stop services
  240. startup
  242. chkconfig –level 2345 httpd on
  244. The tutorial is finished. If you encounter any problems with apache, you can leave messages and communicate with each other...
