CentOS 安装 nginx-1.19.4 与原版本共存

1、下载nginx

http://nginx.org/en/download.html

wget  http://nginx.org/download/nginx-1.19.4.tar.gz

2、解压，进入目录

tar -zxvf nginx-1.19.4.tar.gz

cd nginx-1.19.4

3、修改nginx http header server显示

vim src/http/ngx_http_header_filter_module.c   

找到

static u_char ngx_http_server_string[] = "Server: nginx" CRLF;
static u_char ngx_http_server_full_string[] = "Server: " NGINX_VER CRLF;
static u_char ngx_http_server_build_string[] = "Server: " NGINX_VER_BUILD CRLF;

修改为

static u_char ngx_http_server_string[] = "Server: XXX" CRLF;
static u_char ngx_http_server_full_string[] = "Server: XXX" CRLF;
static u_char ngx_http_server_build_string[] = "Server: XXX" CRLF;

4、编译安装到/usr/local/nginx119

./configure --prefix=/usr/local/nginx119 --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-pcre --with-http_realip_module --with-stream --with-http_v2_module

报错：./configure: error: the HTTP rewrite module requires the PCRE library.

解决：yum -y install pcre-devel openssl openssl-devel

再次 ./configure --prefix=/usr/local/nginx119  --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-pcre --with-http_realip_module --with-stream --with-http_v2_module

通过

make -j 

make install

5、查看安装是否成功

cd /usr/local/nginx119/sbin

./nginx

6、旧版本配置文件迁移

7、配置新的nginx服务，以nginx119命名

nginx.conf 设置

pid        /var/run/nginx119.pid;

到nginx目录下新生成nginx可执行程序软连接nginx119

ln -s nginx nginx119

生成新的服务脚本

------------------------------------centos 6.x start ------------------------------------------------------------

cd /etc/init.d/

cp nginx nginx119

vim nginx119

修改路径相关内容如下：

nginx="/usr/local/nginx119/sbin/nginx119"
prog="$(basename $nginx)"

sysconfig="/etc/sysconfig/${prog}"
lockfile="/var/lock/subsys/nginx119"
pidfile="/var/run/${prog}.pid"

NGINX_CONF_FILE="/usr/local/nginx119/conf/nginx.conf"

创建sysconfig文件

cd /etc/sysconfig/
cp nginx nginx119
vim nginx119
修改原有内容为：

NGINX_CONF_FILE="/usr/local/nginx119/conf/nginx.conf"

service nginx119 start 

service nginx119 status

service nginx119 stop

测试都没问题

------------------------------------------------centos 6.x end --------------------------------------------

-----------------------------------------------centos 7.x start --------------------------------------------

cd /usr/lib/systemd/system

cp nginx.service nginx119.service

vim nginx119.service

systemctl start nginx119.service

systemctl status nginx119.service

systemctl stop nginx119.service

测试都没问题

-----------------------------------------------centos 7.x end-----------------------------------------------

7、配置开机启动

------------------------------------------------centos 6.x start --------------------------------------------

chkconfig nginx119 on

chkconfig nginx off　　# 关闭原来nginx自动启

chkconfig                    # 查看是否开机启动成功

-----------------------------------------------centos 6.x end --------------------------------------------

------------------------------------------------centos 7.x start --------------------------------------------

systemctl enable nginx119.service

systemctl disable nginx.service　　# 关闭原来nginx自动启

systemctl status nginx119.service    # 查看是否开机启动成功

-----------------------------------------------centos 7.x end --------------------------------------------
