ps : nginx安装在/opt/local/nginx里
1.安装编译安装依赖的类库和包
如果需要编译MySQL和PHP，就安装这些
yum install -y make apr* autoconf automake curl curl-devel gcc gcc-c++ gtk+-devel zlib-devel openssl openssl-devel pcre-devel gd kernel keyutils patch perl kernel-headers compat* cpp glibc libgomp libstdc++-devel keyutils-libs-devel libsepol-devel libselinux-devel krb5-devel libXpm* freetype freetype-devel freetype* fontconfig fontconfig-devel libjpeg* libpng* php-common php-gd gettext gettext-devel ncurses* libtool* libxml2 libxml2-devel patch policycoreutils bison
如果只编译nginx，就安装这些
yum install gcc gcc-c++ autoconf automake zlib zlib-devel openssl openssl-devel pcre-devel
2.编译安装pcre
PS：Pcre版本不能太高，8最好，要不编译不能通过
mkdir /usr/local/pcre #创建安装目录
tar zxvf pcre-8.34.tar.gz
cd pcre-8.34
./configure --prefix=/opt/local/pcre #配置
make && make install
3.配置 Nginx 安装选项

nginx binary file: "/opt/local/nginx/sbin/nginx"
nginx modules path: "/opt/local/nginx/modules"
nginx configuration prefix: "/opt/local/nginx/conf"
nginx configuration file: "/opt/local/nginx/conf/nginx.conf"

nginx http uwsgi temporary files: "uwsgi_temp"

编译完成之后注意nginx path prefix 到 nginx http access log file 这几行配置信息，后面需要用的到。
4.安装 Nginx
make && make install
5.配置 systemd Nginx 服务和设置 Nginx 自启动
centos 7 中采用 systemd 来管理系统，我们来为 nginx 创建服务文件，来实现通过 systemd 来管理 nginx 。 创建 systemd 服务文件： /lib/systemd/system/nginx.service，内容如下：
[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/opt/local/nginx/logs/nginx.pid
ExecStartPre=/opt/local/nginx/sbin/nginx -t
ExecStart=/opt/local/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
这里的 PIDFile 的配置要和前面的 配置保持一致。
设置自启动
systemctl enable nginx
通过 systemd 管理 nginx
systemctl start nginx
systemctl stop nginx
systemctl restart nginx
systemctl reload nginx
