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
