一、安裝nginx依賴的軟件
nginx是C寫的，需要用GCC編譯；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。
已安裝的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源碼安裝：
zlib下載官網(wǎng)：http://www.zlib.net/
下載zlib最新版本1.2.11源碼：
[root@VM_2_13_centos stalker]# wget http://prdownloads.sourceforge.net/libpng/zlib-1.2.11.tar.gz
解壓并進(jìn)入zlib代碼根目錄：
[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、編譯、安裝：
[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源碼安裝：
PCRE官網(wǎng)：http://www.pcre.org/
下載PCRE最新版本8.41源碼：
[root@VM_2_13_centos stalker]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.41/pcre-8.41.tar.gz
解壓并進(jìn)入PCRE代碼根目錄：
[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、編譯、安裝：
[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
說明安裝成功。
3、OpenSSL源碼安裝：
OpenSSL官網(wǎng)：https://www.openssl.org/
下載OpenSSL版本1.0.2n源碼：
[root@VM_2_13_centos stalker]# wget https://www.openssl.org/source/openssl-1.0.2n.tar.gz
解壓并進(jìn)入openssl代碼根目錄：
[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、編譯、安裝：
[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、源碼安裝nginx
下載nginx最新穩(wěn)定版本1.12.2源碼：
[root@VM_2_13_centos stalker]# wget wget http://nginx.org/download/nginx-1.12.2.tar.gz
解壓并進(jìn)入nginx代碼根目錄：
[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之后的正確信息如下：
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=
按照提示說明，--with-openssl=
[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
這樣就配置正確，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"
編譯安裝：
[root@VM_2_13_centos nginx-1.12.2]# make
[root@VM_2_13_centos nginx-1.12.2]# make install
檢查nginx.conf配置正確性：
[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
啟動nginx：
[root@VM_2_13_centos ~]# /usr/local/nginx/sbin/nginx
在瀏覽器中輸入主機(jī)IP地址看到如下的頁面說明nginx安裝成功
nginx加入到開機(jī)自動啟動
先編輯系統(tǒng)啟動腳本vim /etc/rc.local 這個文件是系統(tǒng)啟動后會自動執(zhí)行的,我們就將啟動命令加入到這個文件中
[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的進(jìn)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
修改全局的環(huán)境變量
[root@VM_2_13_centos ~]# vim /etc/profile
export PATH=$PATH:/usr/local/MySQL/bin:/usr/local/nginx/sbin
Nginx的默認(rèn)安裝位置
/usr/local/nginx
/usr/local/nginx/conf/nginx.conf //nginx的配置文件
/usr/local/nginx/html //默認(rèn)的網(wǎng)頁文件
