linux如何安装nginx

 　　从官网下载一个nginx 的tar.gz 版。,　　安装方式使用make 安装,　　第一步：解压,　　tar -zxvf nginx-1.7.4.tar.gz,　　第二步：进入nginx-1.7.4，执行./configure 命令,　　----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------,　　[root@localhost nginx-1.7.4]# ./configure,　　checking for OS,　　+ Linux 2.6.32-431.el6.x86_64 x86_64,　　checking for C compiler ... not found,　　./configure: error: C compiler cc is not found,　　出现这个错误。,　　那么就是gcc 包没有安装。安装gcc 吧，骚年。,　　yum -y install gcc,　　----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------,　　再次执行./configure,　　./configure: error: the HTTP rewrite module requires the PCRE library.,　　You can either disable the module by using --without-http_rewrite_module,　　option, or install the PCRE library into the system, or build the PCRE library,　　statically from the source with nginx by using --with-pcre= option.,　　yum install pcre-devel,　　----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------,　　再次执行./configure,　　./configure: error: the HTTP gzip module requires the zlib library.,　　You can either disable the module by using --without-http_gzip_module,　　option, or install the zlib library into the system, or build the zlib library,　　statically from the source with nginx by using --with-zlib= option.,　　yum install zlib-devel,　　----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------,　　再次执行./configure,　　Configuration summary,　　+ using system PCRE library,　　+ OpenSSL library is not used,　　+ using builtin md5 code,　　+ sha1 library is not found,　　+ using system zlib library,　　OK，现在可以执行make 了。如果你想使用openssl 功能，sha1 功能。那么安装openssl ，sha1 吧，骚年。安装opensslyum install openssl openssl-devel安装sha1,　　yum install perl-Digest-SHA1.x86_64,　　开启ssl 模块 执行./configure --with-http_ssl_module,　　启用“server+status"页，执行./configure --with-http_stub_status_module,　　两个都启动，不用我说了。执行./configure --with-http_stub_status_module --with-http_ssl_module,　　----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------,　　那么configre 就通过了。,　　----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------,　　执行make 命令,　　执行make install 命令,　　至此，nginx 执行成功了,　　------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------,　　下来配置环境变量在/etc/profile 中加入：export NGINX_HOME=/usr/local/nginx,　　export PATH=$PATH:$NGINX_HOME/sbin保存，执行 source /etc/profile ，使配置文件生效。执行nginx -v,就能看到版本了，说明nginx 安装成功了,
