使用源码在CentOS 7下安装 apache 2.4.39，之前趟了一遍，简单做个笔记。
STEP 1 安装apr
STEP 1.1 检查是否安装apr
[root@study ~]# yum list apr # 如果没有安装, 则进入STEP 1.2; # 查看apr的位置 [root@study ~]# whereis apr apr: /usr/local/apr
STEP 1.2 安装apr
[root@study ~]# cd source [root@study source]# wget http://DOWNLOAD/apr-1.7.0.tar.gz # DOWNLOAD 替换相应的镜像 [root@study source]# tar -xzvf apr-1.7.0.tar.gz [root@study source]# cd apr-1.7.0 [root@study apr-1.7.0]# ./configure --prefix=/usr/local/apr [root@study apr-1.7.0]# make && make install
STEP 2 安装libxml2
由于apahce 依赖的apr-util.1.6.1依赖libxml2库，如果没有安装libxml2库，则在apache的配置中会有如下错误产生:
usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_GetErrorCode' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_SetEntityDeclHandler' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_ParserCreate' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_SetCharacterDataHandler' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_ParserFree' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_SetUserData' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_StopParser' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_Parse' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_ErrorString' /usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_SetElementHandler' collect2: error: ld returned 1 exit status make[2]: *** [htpasswd] 错误 1 make[2]: 离开目录“/opt/source/apache.httpd/httpd-2.4.39/support” make[1]: *** [all-recursive] 错误 1 make[1]: 离开目录“/opt/source/apache.httpd/httpd-2.4.39/support” make: *** [all-recursive] 错误 1
STEP 2.1 检查是否安装 libxml2
[root@study ~]# yum list libxml2 # 如果没有安装则，进行libxml2安装 [root@study ~]# yum install libxml2-devel
STEP 3 安装expat
如果没有安装expat，可能在安装apr-util中会报如下错误：
xml/apr_xml.c:35:19: 致命错误：expat.h：没有那个文件或目录 #include <expat.h>
STEP 3.1 检查是否安装expat
[root@study ~]# yum list expat # 如果没有安装则进行安装 [root@study ~]# yum install expat-devel
STEP 4 安装apr-util
STEP 4.1 检查是否安装apr-util
[root@study ~]# yum list apr-util # 如果没有安装则进入 STEP 4.2 进行安装 [root@study ~]# whereis apr-util apr-util: /usr/local/apr-util
STEP 4.2 安装apr-util
[root@study ~]# cd source [root@study source]# wget http://DOWNLOAD/apr-util-1.6.1.tar.gz [root@study source]# tar -xzvf apr-util-1.6.1.tar.gz [root@study source]# cd apr-util.1.6.1 [root@study apr-util.1.6.1]# ./configure --prefix=/usr/local/apr-util [root@study aapr-util.1.6.1]# make && make install
STEP 5 安装pcre
STEP 5.1 检查是否安装pcre
[root@study ~]# yum list pcre # 如果没有安装，则进入 STEP 5.2 进行安装 [root@study ~]# whereis pcre pcre: /usr/include/pcre.h /usr/local/pcre /usr/share/man/man3/pcre.3.gz
STEP 5.2 安装pcre
[root@study ~]# cd source [root@study ~]# url=https://jaist.dl.sourceforge.net/project/pcre/pcre/8.43/pcre-8.43.tar.gz [root@study source]# wget ${url} [root@study source]# tar -xzvf pcre-8.43.tar.gz [root@study source]# cd pcre-8.43 [root@study pcre-8.43]# ./configure --prefix=/usr/local/pcre [root@study pcre-8.43]# make && make install
STEP 6 安装apache
[root@study source]# tar -xzvf http-2.4.39.tar.gz [root@study source]# cd httpd-2.4.39 [root@study httpd-2.4.39]# ./configure --prefix=/usr/local/apache24 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre [root@study httpd-2.4.39]# make && make install
STEP 7 设置service文件
[root@study ~]# cd /usr/lib/systemd/system [root@study system]# vim httpd.service [Unit] Description=Apache 2.4.39 After=network.target After=syslog.target [Service] Type=forking ExecStart=/usr/local/apache24/bin/apachectl -k start ExecStop=/usr/local/apache24/bin/apachectl -k stop ExecReload=/usr/local/apache24/bin/apachectl -k restart [Install] WantedBy=multi-user.target Alias=http.service
STEP 8 设置防火墙以及开机启动
# 允许开放http服务 [root@study ~]# firewall-cmd --permanent --add-service=http # 打开http服务的80 tcp端口 [root@study ~]# firewall-cmd --permanent --add-port=80/tcp # 重新加载防火墙规则 [root@study ~]# firewall-cmd --reload # 重新启动apach [root@study ~]# systemctl restart httpd.service # 设置开机启动 [root@study ~]# systemctl enable httpd.service
