快速安装脚本
1、该脚本可快速一键安装Nginx(适用于CentOS，其他环境可自行调整脚本) 2、脚本内容请自行下载文件并查看 3、Nginx使用淘宝Tengine版本，下载链接，如果安装时有新版本，可以尝试替换下载链接为新版本 4、脚本安装临时目录在/data0/temp/目录，安装完成后可直接删除

yum -y install libjpeg
yum -y install libjpeg-devel
yum -y install freetype
yum -y install freetype-devel
yum -y install libxml2
yum -y install libxml2-devel
yum -y install zlib
yum -y install zlib-devel
yum -y install glibc
yum -y install glibc-devel
yum -y install glib2
yum -y install glib2-devel
yum -y install bzip2
yum -y install bzip2-devel
yum -y install curl
yum -y install curl-devel
yum -y install make
yum -y install gd
yum -y install gd-devel
yum -y install gd2
yum -y install gd2-devel
yum -y install git
yum -y install unzip
yum -y install git
yum -y install cmake
yum -y install patch
yum -y install lrzsz
yum -y install iftop
yum -y install openssl-devel
yum -y install openssl
yum -y nss安装脚本文件解析
注意：以下步骤为帮助读者理解脚本内容，因脚本里面会适用一些前后关联的变量，不能直接运行脚本，完整内容请下载 http://cdn.laohand.com/sh/install_nginx.sh
创建用户、获取系统内存信息
1、downloadFile函数用于下载文件，该方法在文件存在时不会重复下载文件，对于调试脚本多次运行时有帮助，另外在下载文件失败时终止程序 2、注意downloadFile下载文件不完整时，该方法无法检测并且不会重新下载，需要手动清理不完整文件(网络差时可能遇到)
#!/bin/bash
tempPath="/data0/temp/"
mkdir ${tempPath}
cpuNum=$(cat /proc/cpuinfo | grep processor | wc -l)
function downloadFile(){
saveFilename=$1
downloadUrl=$2
if [ ! -f ${saveFilename} ];then
wget -O ${saveFilename} "${downloadUrl}"
if [ ! -f ${saveFilename} ];then
echo "${saveFilename} download fail url=><a class="external" href="" title="查看与 相关的文章" target="_blank"></a>${saveFilename}"
exit
fi
fi
}
groupadd -f www
useradd -g www www安装openssl
如果已经安装openssl，可忽略该步骤，使用https时需要openssl库，强烈建议安装
cd ${tempPath}
downloadFile openssl-1.0.2p.tar.gz https://www.openssl.org/source/openssl-1.0.2p.tar.gz
tar xzf openssl-1.0.2p.tar.gz
opensslDir=${tempPath}/openssl-1.0.2p
cd openssl-1.0.2p
./config --prefix=/usr && make -j ${cpuNum} && make install安装jemalloc
该步骤可选，建议安装jemalloc优化nginx内存分配，如已安装可直接跳过
cd ${tempPath}
downloadFile jemalloc-5.1.0.tar.bz2 https://github.com/jemalloc/jemalloc/releases/download/5.1.0/jemalloc-5.1.0.tar.bz2
tar jxf jemalloc-5.1.0.tar.bz2
jemallocDir=${tempPath}/jemalloc-5.1.0安装Nginx
cd ${tempPath}
downloadFile tengine-2.2.3.tar.gz http://tengine.taobao.org/download/tengine-2.2.3.tar.gz
tar xzf tengine-2.2.3.tar.gz && cd tengine-2.2.3
./configure --prefix=/usr/local/nginx \
--user=www --group=www \
--with-jemalloc \
--with-ld-opt=-lrt \
--with-openssl=${opensslDir} \
--with-jemalloc=${jemallocDir} \
--with-http_stub_status_module \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_gzip_static_module \
--with-pcre
make -j ${cpuNum} && make install配置nginx主配置文件
该配置文件适用于比较通用的场景，如需要特殊配置，请自行修改配置文件

启动、重启Nginx
建议直接用命令维护nginx，以便更能掌握nginx，而且在所有操作系统中都适用
# 启动Nginx
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx/conf
# 检测Nginx配置文件
/usr/local/nginx/sbin/nginx -t
# 重启Nignx
/usr/local/nginx/sbin/nginx -s© 版权声明
