搭建OpenResty

openresty官网：http://openresty.org/

安装之前首先要确认系统的基础环境

1. gcc编译器

# yum install -y gcc 

2. curl库

# yum install -y curl

3. pcre、zlib、openssl开发库(其openssl会依赖pcre和zlib)

# yum install -y pcre-devel zlib-devel openssl-devel

4. 如启用postgres模块，还需安装postgresql开发库，否则会报错：ngx_postgres addon was unable to detect version of the libpq library

# yum install -y postgresql-devel

5. 准备OpenResty源码包官网下载连接：https://openresty.org/cn/download.html

① 准备安装openresty，解压源码包

# tar -xvzf openresty-x.x.x.x.tar.gz
# cd openresty-x.x.x.x

② 设置配置选项

# ./configure --prefix=/opt/openresty --with-luajit --with-http_iconv_module --with-http_postgres_module

默认的prefix目录为：/usr/local/openresty，这里指定到/opt/openresty

–with-luajit在1.5.8.1之后已经默认开启，不加也是启用的

③ 编译并安装源码

# make -j4
# make install

6. cd到/opt/openresty/nginx/sbin/，./nginx 来启动nginx，./nginx -s reload 来重启nginx
