一、安装nginx依赖的软件

nginx是C写的，需要用GCC编译；nginx中的rewrite module需要PCRE；nginx中的gzip module需要zlib；nginx中的HTTP SSL module需要OpenSSL。

已安装的GCC版本信息如下：

[root@VM_2_13_centos ~]# gcc -v

Using built-in specs.

COLLECT_GCC=gcc

COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-redhat-linux/4.8.5/lto-wrapper

Target: x86_64-redhat-linux

Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-linker-hash-style=gnu --enable-languages=c,c++,objc,obj-c++,java,fortran,ada,go,lto --enable-plugin --enable-initfini-array --disable-libgcj --with-isl=/builddir/build/BUILD/gcc-4.8.5-20150702/obj-x86_64-redhat-linux/isl-install --with-cloog=/builddir/build/BUILD/gcc-4.8.5-20150702/obj-x86_64-redhat-linux/cloog-install --enable-gnu-indirect-function --with-tune=generic --with-arch_32=x86-64 --build=x86_64-redhat-linux

Thread model: posix

gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC)

1、zlib源码安装：

zlib下载官网：http://www.zlib.net/

下载zlib最新版本1.2.11源码：

[root@VM_2_13_centos stalker]# wget http://prdownloads.sourceforge.net/libpng/zlib-1.2.11.tar.gz

解压并进入zlib代码根目录：

[root@VM_2_13_centos stalker]# tar zxvf zlib-1.2.11.tar.gz

[root@VM_2_13_centos stalker]# cd zlib-1.2.11

配置、编译、安装：

[root@VM_2_13_centos zlib-1.2.11]# ./configure

[root@VM_2_13_centos zlib-1.2.11]# make

[root@VM_2_13_centos zlib-1.2.11]# make install

rm -f /usr/local/lib/libz.a

cp libz.a /usr/local/lib

chmod 644 /usr/local/lib/libz.a

cp libz.so.1.2.11 /usr/local/lib

chmod 755 /usr/local/lib/libz.so.1.2.11

rm -f /usr/local/share/man/man3/zlib.3

cp zlib.3 /usr/local/share/man/man3

chmod 644 /usr/local/share/man/man3/zlib.3

rm -f /usr/local/lib/pkgconfig/zlib.pc

cp zlib.pc /usr/local/lib/pkgconfig

chmod 644 /usr/local/lib/pkgconfig/zlib.pc

rm -f /usr/local/include/zlib.h /usr/local/include/zconf.h

cp zlib.h zconf.h /usr/local/include

chmod 644 /usr/local/include/zlib.h /usr/local/include/zconf.h

[root@VM_2_13_centos zlib-1.2.11]# whereis zlib

zlib: /usr/include/zlib.h /usr/share/man/man3/zlib.3.gz

2、PCRE源码安装：

PCRE官网：http://www.pcre.org/

下载PCRE最新版本8.41源码：

[root@VM_2_13_centos stalker]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.41/pcre-8.41.tar.gz

解压并进入PCRE代码根目录：

[root@VM_2_13_centos stalker]# tar zxvf pcre-8.41.tar.gz

[root@VM_2_13_centos stalker]# cd pcre-8.41

配置、编译、安装：

[root@VM_2_13_centos pcre-8.41]# ./configure

[root@VM_2_13_centos pcre-8.41]# make

[root@VM_2_13_centos pcre-8.41]# make install

查看版本：

[root@VM_2_13_centos pcre-8.41]# pcre-config --version

8.41

说明安装成功。

3、OpenSSL源码安装：

OpenSSL官网：https://www.openssl.org/

下载OpenSSL版本1.0.2n源码：

[root@VM_2_13_centos stalker]# wget https://www.openssl.org/source/openssl-1.0.2n.tar.gz

解压并进入openssl代码根目录：

[root@VM_2_13_centos stalker]# tar zxvf openssl-1.0.2n.tar.gz

[root@VM_2_13_centos stalker]# cd openssl-1.0.2n

配置、编译、安装：

[root@VM_2_13_centos openssl-1.0.2n]# ./config

[root@VM_2_13_centos openssl-1.0.2n]# make

[root@VM_2_13_centos openssl-1.0.2n]# make install

二、源码安装nginx

下载nginx最新稳定版本1.12.2源码：

[root@VM_2_13_centos stalker]# wget wget http://nginx.org/download/nginx-1.12.2.tar.gz

解压并进入nginx代码根目录：

[root@VM_2_13_centos stalker]# tar zxvf nginx-1.12.2.tar.gz

[root@VM_2_13_centos stalker]# cd nginx-1.12.2

配置：

[root@VM_2_13_centos nginx-1.12.2]# ./configure --with-http_ssl_module --with-pcre=../pcre-8.41 --with-zlib=../zlib-1.2.11

./configure之后的正确信息如下：

Configuration summary

+ using PCRE library: ../pcre-8.41

+ using system OpenSSL library

+ using zlib library: ../zlib-1.2.11

nginx path prefix: "/usr/local/nginx"

nginx binary file: "/usr/local/nginx/sbin/nginx"

nginx modules path: "/usr/local/nginx/modules"

nginx configuration prefix: "/usr/local/nginx/conf"

nginx configuration file: "/usr/local/nginx/conf/nginx.conf"

nginx pid file: "/usr/local/nginx/logs/nginx.pid"

nginx error log file: "/usr/local/nginx/logs/error.log"

nginx http access log file: "/usr/local/nginx/logs/access.log"

nginx http client request body temporary files: "client_body_temp"

nginx http proxy temporary files: "proxy_temp"

nginx http fastcgi temporary files: "fastcgi_temp"

nginx http uwsgi temporary files: "uwsgi_temp"

nginx http scgi temporary files: "scgi_temp"

如果./configure提示OpenSSL找不到：

checking for OpenSSL library ... not found

checking for OpenSSL library in /usr/local/ ... not found

checking for OpenSSL library in /usr/pkg/ ... not found

checking for OpenSSL library in /opt/local/ ... not found

./configure: error: SSL modules require the OpenSSL library.

You can either do not enable the modules, or install the OpenSSL library

into the system, or build the OpenSSL library statically from the source

with nginx by using --with-openssl= option.

按照提示说明，--with-openssl=即可。

[root@VM_2_13_centos nginx-1.12.2]# ./configure --with-http_ssl_module --with-pcre=../pcre-8.41 --with-zlib=../zlib-1.2.11 --with-openssl=../openssl-1.0.2n

这样就配置正确，信息如下：

Configuration summary

+ using PCRE library: ../pcre-8.41

+ using OpenSSL library: ../openssl-1.0.2n

+ using zlib library: ../zlib-1.2.11

nginx path prefix: "/usr/local/nginx"

nginx binary file: "/usr/local/nginx/sbin/nginx"

nginx modules path: "/usr/local/nginx/modules"

nginx configuration prefix: "/usr/local/nginx/conf"

nginx configuration file: "/usr/local/nginx/conf/nginx.conf"

nginx pid file: "/usr/local/nginx/logs/nginx.pid"

nginx error log file: "/usr/local/nginx/logs/error.log"

nginx http access log file: "/usr/local/nginx/logs/access.log"

nginx http client request body temporary files: "client_body_temp"

nginx http proxy temporary files: "proxy_temp"

nginx http fastcgi temporary files: "fastcgi_temp"

nginx http uwsgi temporary files: "uwsgi_temp"

nginx http scgi temporary files: "scgi_temp"

编译安装：

[root@VM_2_13_centos nginx-1.12.2]# make

[root@VM_2_13_centos nginx-1.12.2]# make install

检查nginx.conf配置正确性：

[root@VM_2_13_centos ~]# /usr/local/nginx/sbin/nginx -t

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

启动nginx：

[root@VM_2_13_centos ~]# /usr/local/nginx/sbin/nginx

在浏览器中输入主机IP地址看到如下的页面说明nginx安装成功

CentOS 7.4下安装nginx的步骤是什么

nginx加入到开机自动启动

先编辑系统启动脚本vim /etc/rc.local 这个文件是系统启动后会自动执行的,我们就将启动命令加入到这个文件中

[root@VM_2_13_centos ~]# vim /etc/rc.local

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf & >/tmp/nginx.log 2>&1

查看nginx的进程

[root@VM_2_13_centos ~]# ps -ef | grep nginx

root 16976 16360 0 18:03 pts/2 00:00:00 grep --color=auto nginx

root 25192 1 0 13:25 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx

nobody 25769 25192 0 13:37 ? 00:00:00 nginx: worker process

修改全局的环境变量

[root@VM_2_13_centos ~]# vim /etc/profile

export PATH=$PATH:/usr/local/mysql/bin:/usr/local/nginx/sbin

Nginx的默认安装位置

/usr/local/nginx

/usr/local/nginx/conf/nginx.conf //nginx的配置文件

/usr/local/nginx/html //默认的网页文件
