哇，我的博客终于在经历db挂掉后回来了，真是太难了，后面具体再来写一次关于db升级的处理吧。今天先写下重装我的环境的心路历程
1. 首先下载安装包
1
| wget http://nginx.org/download/nginx-1.18.0.tar.gz
|
2. 解压安装包
1
| tar -zxvf nginx-1.18.0.tar.gz
|
3. 进入解压后的安装包
4. 执行config

| ./configure \
--user=www \
--group=www \
--prefix=/usr/local/nginx \
--with-http_ssl_module \
--with-http_stub_status_module \
--with-http_realip_module \
--with-threads \
--with-http_v2_module
|
其中 /usr/local/nginx 是对应的安装目录， www是对应的用户及用户组，我在执行的时候会提示某些软件未安装具体的报错如下

| ./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.
|
这里是需要安装pcre-devel、openssl、openssl-devel这三个依赖，具体命令如下
1
| yum -y install pcre-devel openssl openssl-devel
|
5. 接下来就是编译和安装了
6. 验证
1
| /usr/local/nginx/sbin/nginx -V
|
输出如下

| nginx version: nginx/1.18.0
built by gcc 8.3.1 20191121 (Red Hat 8.3.1-5) (GCC)
built with OpenSSL 1.1.1c FIPS 28 May 2019 (running with OpenSSL 1.1.1g FIPS 21 Apr 2020)
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-threads --with-http_v2_module
|
7. 创建软连
1
| ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx
|
8. 开机自启动
